OpenSSL create certificate chain requires Root and Intermediate Certificate. In this step you'll take the place of VeriSign, Thawte, etc. Use the Root CA key cakey.pem to create a Root CA certificate cacert.pem. Give the root certificate a long expiry date Create Certificate chain and sign certificates using Openssl Generate Root Certificate key. openssl genrsa -out RootCA.key 4096 Generate Root certificate. openssl req -new -x509 -days 1826 -key RootCA.key -out RootCA.crt Generate Intermediate CA certificate key openssl genrsa -out IntermediateCA.key.
Now we have a valid certificate chain, which will enable us to create a pkcs12 archiv. $ openssl pkcs12 \ -export \ -in myUser.crt \ -inkey myUser.key \ -passin file:userPassfile \ -CAfile myPrivateCA.crt \ -name MyUsercertificate \ -out myUser.pkcs1 You can also generate certificate chains pretty easily with KeyStore Explorer: Create a new key pair, which implies creating a self-signed certificate (the root CA). Right click on root CA certificate and select Sign New Key Pair, this creates the sub CA certificate and key pair
How to create a PEM file with the help of an automated script: Download NetIQ Cool Tool OpenSSL-Toolkit. Select Create Certificates | PEM with key and entire trust chain Provide the full path to the directory containing the certificate files . cat./root/rootca.crt intermediate1.crt > enduser-certs/enduser-example.com.chain Send the following files to the end user
To create a file with the certificate chain you can run: $cat STAR_mydomain.crt TrustedSecureCertificateAuthority5.crt USERTrustRSAAddTrustCA.crt > Certificate_Chain.crt For such services as AWS. What I'd like to do then is create my own cert chain. The whole TLS/SSL stuff is still a bit hazy to me, but as I can see, one first create a master key, with openssl genrsa then create a self-signed certificate using that key with openssl req -x509 -new to create the CA. Then I can create new keys, and certificate signing requests with openssl. To add the root certificate to the keychain open Keychain Access in OSX and drop the rootCA.pem in it from Finder. This will add the certificate to the store but is not yet enough to trust the SSL certificate. In order to trust the SSL certificate it is needed to tell OSX the root certificate is trusted for performing X.509 Basic Policy tasks That chain may or may not be in PEM format and may need to be converted using OpenSSL. For simplicity, let's assume that you may have an easier method to get YOUR chain but I'll show how to build the chain by hand. Above we the the certificate chain for the SSL certificate issued for mysite.lab.local . This means that your web server is sending out all certificates needed to validate its certificate, except the root certificate. This is best practice and helps you achieving a good rating from SSL Labs. In a normal situation, your server certificate is signed by an intermediate CA. With this, your complete certificate chain is composed of the Root CA, intermediate CA and server certificate

subject= /CN=the name of the intermediate CA. This should match with the issuer of the certificate. We can do the same validation on the intermediate certificate, as the issuer on the intermediate. From commandline, openssl verify will if possible build (and validate) a chain from the/each leaf cert you give it, plus intermediate (s) from -untrusted (which can be repeated), and possibly more intermediate (s) to a root (or anchor) in -trusted or -CAfile and/or -CApath or the default truststore, which is usually determined by your system or build but can be overridden with envvars
OpenSSL is an open source toolkit that can be used to create test certificates, as well as generate certificate signing requests (CSRs) which are used to obtain certificates from trusted third-party Certificate Authorities. More Information. Certificates are used to establish a level of trust between servers and clients. There are two types of certificate, those used on the server side, and those which are used by the client to authenticate the session. SocketTools supports both. Create your root CA certificate using OpenSSL. Create the root key Sign in to your computer where OpenSSL is installed and run the following command. This creates an encrypted key Create free Team Teams. Q&A for work. Connect and share knowledge within a single location that is structured and easy to search. Learn more How to export CA certificate chain from PFX in PEM format without bag attributes. Ask Question Asked 4 years ago. Active 4 months ago. Viewed 113k times 51. 20. I have a PKCS12 file containing the full certificate chain and private key. I need to break it. The next most common use case of OpenSSL is to create certificate signing requests for requesting a certificate from a certificate authority that is trusted. openssl req -new -newkey rsa:2048 -nodes -out request.csr -keyout private.key. Similar to the previous command to generate a self-signed certificate, this command generates a CSR. You will notice that the -x509, -sha256, and -days.
The list of steps to be followed to generate server client certificate using OpenSSL and perform further verification using Apache HTTPS: Create server certificate. Generate server key. Generate Certificate Signing Request (CSR) with server key. Generate and Sign the server certificate using CA key and certificate Generate a CSR from an Existing Certificate and Private key. Here we can generate or renew an existing certificate where we miss the CSR file due to some reason. Here, the CSR will extract the information using the .CRT file which we have. Below is the example for generating - $ openssl x509 in domain.crt-signkey domain.key -x509toreq -out. You can do this by downloading the Apache download link from your SSL.com account, and including both your website certificate and the file named ca-bundle-client.crt in your PFX file. For example: openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile ca-bundle-client.cr Now open up your root certificate and just paste the contents below your intermediate certificate. Save your new certificate to something like verisign-chain.cer. Now fire up openssl to create your .pfx file. The command you need to use is: pkcs12 -export -out your_cert.pfx -inkey your_private.key -in your_cert.cer -certfile verisign-chain.ce Today, let's figure out how to convert a CRT SSL certificate chain to PFX format. First, let's generate a private key and certificate signing request. Run the following command, and answer the questions as accurately as possible. The private key file ( domain.key) should be kept secret and protected. openssl req \ -newkey rsa:2048 -nodes.
This command creates a self-signed certificate ( domain.crt) from an existing private key ( domain.key ): openssl req \ -key domain.key \ -new \ -x509 -days 365 -out domain.crt. Answer the CSR information prompt to complete the process. The -x509 option tells req to create a self-signed cerificate Mac OS X also ships with OpenSSL pre-installed. For Windows a Win32 OpenSSL installer is available. Remember, it's important you keep your Private Key secured; be sure to limit who and what has access to these keys. Certificates. Converting PEM encoded certificate to DER. openssl x509 -outform der -in certificate.pem -out certificate.der Well actually, there's an easier solution. Assuming you have OpenSSL installed (default available on Mac OS X and Linux systems) have a look at the s_client command: openssl s_client -host google.com -port 443 -prexit -showcerts. The above command prints the complete certificate chain of google.com to stdout
This section provides the steps to generate certificate chains and other required files for a secure connection using OpenSSL. A certificate chain is provided by a Certificate Authority (CA). There are many CAs. Each CA has a different registration process to generate a certificate chain. Follow the steps provided by your CA for the process to obtain a certificate chain from them. As a pre. openssl create certificate chain provides a comprehensive and comprehensive pathway for students to see progress after the end of each module. With a team of extremely dedicated and quality lecturers, openssl create certificate chain will not only be a place to share knowledge but also to help students get inspired to explore and discover many. Create a Chain Certificate (Root, Intermediate & Normal Chain) - Step-by-step ----- ROOT CERTIFICATE ----- mkdir /root/ca cd /root/ca mkdir certs crl newcerts private chmod 700 private touch index.txt echo 1000 > serial vim openssl.cnf [ ca ] # `man ca` default_ca = CA_default [ CA_default ] # Directory and file locations. dir = /root/c Moreover, if I create a chain the certificate is also OK. cat /etc/certs/cacert.pem subCA_websites.crt > chain.pem openssl verify -CAfile chain.pem cups1.crt cups1.crt: OK Now, I also want Windows to see these certificates as valid. And here is the problem: Windows does not see the certificate chain
OpenSSL config file.key: Private key (plain text).key.enc: Private key (encryped with passphrase).csr: Certificate Signing Request.crt: Certificate.ca-bundle: CA chain (intermediate + root certificates).p12: Certificate, private key and CA chain in PKCS #12 forma Use the root certificate to create the server certificate. openssl x509 -req -days 365 -sha1 -extensions v3_req -CA root.crt -CAkey root.key -CAcreateserial -in server.csr -out server.crt. Creating MQTT Client certificate. The above procedure followed for the server certificate can be used to create the client certificates. Please use appropriate name for the files. The above certificates are. Steps to create the KeyStore with a certificate chain. Concatenate the server certificate, the intermediate certificate, and root certificate. If they were provided as separate files by the certificate authority. Then the order of these 3 certificates should be : For Unix use. cat myserver.srt intermediate.crt root.crt > cert-chain.txt . For windows use notepad to concaenate certificates. Pack. Checking A Remote Certificate Chain With OpenSSL. If you deal with SSL/TLS long enough you will run into situations where you need to examine what certificates are being presented by a server to the client. The best way to examine the raw output is via (what else but) OpenSSL. 1. First let's do a standard webserver connection (-showcerts. openssl> crl2pkcs7 -nocrl -certfile cert1.crt -certfile cert2.crt -certfile cert3.crt -out outfile.p7b NOTE: The command creates a certificate chain file from the 'cert1.crt, cert2.crt, cert3.crt' files called outfile.p7b. The p7b file contains the entire certificate chain, which can now be supplied to ePO. The order of the chain must have the.
Now you can start OpenSSL, type: c:\OpenSSL-Win32\bin\openssl.exe: And from here on, the commands are the same as for my Howto: Make Your Own Cert With OpenSSL. First we generate a 4096-bit long RSA key for our root CA and store it in file ca.key Due that your corporate might generate a self signed certificate and which eventually results in SSL certificate problem: self signed certificate in certificate chain 1 $ vagrant up 2 Bringing machine 'master' up with 'virtualbox' provider.. . To convert certificates use OpenSSL. Openssl is a command line open source SSL client that is mainly used on Unix systems however there is a version for Windows that is able to convert certificate types. Firstly, ensure that you have OpenSSL on.
Create a Self-Signed Certificate openssl req -x509 -sha256 -nodes -newkey rsa:2048 -keyout gfselfsigned.key -out gfcert.pem. The above command will generate a self-signed certificate and key file with 2048-bit RSA. I have also included sha256 as it's considered most secure at the moment. Tip: by default, it will generate a self-signed certificate valid for only one month so you may consider. Step 1: Generate a key pair and a signing request. Create a PEM format private key and a request for a CA to certify your public key. Create a configuration file openssl.cnf like the example below: . Or make sure your existing openssl.cnf includes the subjectAltName extension.; Replace <your.domain.com> with the complete domain name of your Code42 server OpenSSL - CSR content . View the content of CA certificate. We can use our existing key to generate CA certificate, here ca.cert.pem is the CA certificate file: ~]# openssl req -new -x509 -days 365 -key ca.key -out ca.cert.pem. To view the content of CA certificate we will use following syntax JAVA,KEYTOOL,CERTIFICATE CHAIN,CERTIFICATE.JDK provides a command line tool -- keytool to handle key and certificate generation. This tool has a set of options which can be used to generate keys, create certificates, import keys, install Pixelstech, this page is to provide vistors information of the most updated technology information around the world Create a pfx file with a certificate chain. Posted on December 15, 2016 by Computer-Tech-Blog. I ran into an issue where an application would not accept the pfx file that I created for a web server. I used the key file and the certificate file but for some reason it did not work. I had to include the certificate chain which had the root CA and intermediate certificates combined in it. If you.
Creating a PKCS7 (P7B) Using OpenSSL . Search results. March 20th, 2009 Continuing the howto nature of this blog (and its peculiar obsession with OpenSSL), here's a primer on packaging an arbitrary number of certificates into a single PKCS7 container. These files are quite useful for installing multiple certificates on Windows servers. They differ from PKCS12 (PFX) files in that they can't. If you receive the server certificate, intermediate certificate and root certificate separately in DER format, you need to convert them to PEM format and follow the above point C to create the chain certificate. The commands are: openssl x509 -inform der -in certificate.cer -out certificate.pem cat server_cert.pem inter_cert.pem root_cert.pem. Hi, I'm using Certify The Web application for wildcard-certificate renewal on dedicated IIS server. It works great. Now I'm trying to load this certificate to the separate shared hosting, but control panel asks to include a full certificate chain to that wildcard-certificate. I downloaded cert.pfx from IIS Manager server certificates and made cert.pem using openssl tool: openssl pkcs12.
openssl: This is the command line tool for creating and managing OpenSSL certificates, keys, and other files. req -x509: This specifies that we want to use X.509 certificate signing request (CSR) management. X.509 is a public key infrastructure standard that SSL and TLS adhere to for key and certificate management. -nodes: This tells OpenSSL to skip the option to secure our certificate with a. Creating a self-signed certificate. The program we need to create a self-signed certificate using openSSL is called openssl.exe and is located in C:\OpenSSL-Win64\bin. Make sure to run your console as an administrator in order to be able to create any certificates. If you configured your openSSL directory in your system path, that's fine
openssl pkcs7 -in p7-0123456789-1111.p7b-inform DER -out result.pem -print_certs b) Now create the pkcs12 file that will contain your private key and the certification chain: openssl pkcs12 -export -inkey your_private_key.key-in result.pem -name my_name -out final_result.pf Use the following OpenSSL commands to create a PKCS#12 file from your private key and certificate. If you have one certificate, use the CA root certificate. openssl pkcs12 -export -in <signed_cert_filename> -inkey <private_key_filename> -name 'tomcat' -out keystore.p12 . If you have a chain of certificates, combine the certificates into a single file and use it for the input file, as shown. To create the keystore from an existing private key and certificate, run the following command: openssl pkcs12 \ -export \ -in certificate.pem \ -inkey key.pem \ -out keystore.p12. OpenSSL Option. Description. pkcs12
In this article. The following example creates and installs a nondefault certificate chain engine. The engine is used to build certificate chains for each of the certificates in a certificate store.. This example illustrates the following tasks and CryptoAPI functions:. Preparing to create a nondefault certificate chain engine by declaring and initializing a CERT_CHAIN_ENGINE_CONFIG data. The following examples show how to create a password protected PKCS #12 file that contains one or more certificates. For more information about the openssl pkcs12 command, enter man pkcs12.. PKCS #12 file that contains one user certificate. openssl pkcs12 -export -in user.pem -caname user alias-nokeys -out user.p12 -passout pass:pkcs12 password; PKCS #12 file that contains one user certificate. Now we will start using OpenSSL to create the necessary keys and certificates. First generate the private/public RSA key pair: openssl genrsa -aes256 -out ca.key.pem 2048 chmod 400 ca.key.pem. This encodes the key file using an passphrase based on AES256. Then we need to create the self-signed root CA certificate
Creating OpenSSL x509 certificates. 29. June 2017 There are (still) various servers on the internet that have just an insufficient SSL/TLS configuration or none at all. It is not just web servers (like nginx or Apache) but also XMPP/Jabber servers and mail servers, for example. As the basis of each SSL/TLS configuration, we need keys and certificates and sometimes Diffie-Hellman parameters. Certificate revocation lists. A certificate revocation list (CRL) provides a list of certificates that have been revoked. A client application, such as a web browser, can use a CRL to check a server's authenticity. A server application, such as Apache or OpenVPN, can use a CRL to deny access to clients that are no longer trusted Setup Self-Signed Certificate Chains with OPNsense¶. This how-to describes the process of creating self-signed certificate chains with the help of OPNsense which has all the tools available to do so.. Chains give the possibility to verify certificates where a single one is nothing more than that, a single certificate To install this example.com.crt certificate, we need to create a chain certificate file. The chain certificate file, as the name indicates provides a complete path for trust verification. Chain certificate file is nothing but a single file which contains all three certificates(end entity certificate, intermediate certificate, and root certificate). This can be done by simply appending one.
openssl pkcs12 -export -out certificate.pfx -inkey mykey.key -in mycrt.crt -certfile chaincert.crt. It will ask for a new pin code. The output is a p12 formatted file with the name certificate.pfx. The p12 file now contains all certificates and keys. Now you can create a SAPSSLS.pse with the following command Signing Certificates With Your Own CA. The example in this section shows how to create a Certificate Signing Request with keytool and generate a signed certificate for the Certificate Signing Request with the CA created in the previous section. The steps shown in this section, for generating a KeyStore and a Certificate Signing Request, were already explained under Creating a KeyStore in JKS. openssl pkcs12 -export -inkey pub-sec-key.pem-certfile certificate-chain.pem -out pub-sec-key-certificate-and-chain.p12 -in signed-certificate.pem Erzeugt die PKCS#12-Datei pub-sec-key-certificate-and-chain.p12 für den Import nach MS Windows 2000 oder MS Windows XP zur späteren Nutzung durch den MS Internet Information Server (IIS)
With the openssl req-new command we create the private key and CSR for an email-protection certificate. We use a request configuration file specifically prepared for the task. When prompted enter these DN components: DC=org, DC=simple, O=Simple Inc, CN=Fred Flintstone, emailAddressemail@example.com. Leave other fields empty. 3.2 Create email certificate¶ openssl ca \-config etc/signing-ca.conf. This makes it possible to generate certificates on the fly, tools like Charles Web proxy, Fiddler use this technique for intercepting SSL traffic. So now we will look at how to create a root certificate and then generate a certificate signed using our root certificate. Below is a sample shell script to make it easy to generate these certificates A Simple Step-By-Step Guide To Apache Tomcat SSL Configuration Secure Socket Layer (SSL) is a protocol that provides security for communications between client and server by implementing encrypted data and certificate-based authentication. Technically, the term SSL now refers to the Transport Layer ouSecurity (TLS) protocol, which is based on the original SSL specification Also, a question if you have time, did you ever figure out how to export the entire certificate chain if you do Create() with an issuer cert? When I do an export on that, it only has the final certit does not contain the CAs/Signing CA public info that issued it. Reply. Travis says: 2019-10-25 at 20:26. After further inspection, it looks like the chain might be in there. Generally I examine. Combine the certificate chain (in this example, it is named All-certs.pem) certificates with the private key that you generated along with the CSR (the private key of the device certificate, which is mykey.pem in this example) if you went with option A (that is, you used OpenSSL to generate the CSR), and save the file as final.pem. If you generated the CSR directly from the WLC (option B.
If you don't install one or more intermediate SSL certificate, you break the certificate chain. That means you create a gap between a specific (end-user or intermediate) certificate and its issuer. When a device can't find a trusted issuer for a certificate, the certificate and the entire chain, from the intermediate certificate down to the final cerficate, can't be trusted. As a result Verify Openssl Installation Step 2: Create a Local Self-Signed SSL Certificate for Apache. 3. With the Apache web server and all the prerequisites in check, you need to create a directory within which the cryptographic keys will be stored. In this example, we have created a directory at /etc/ssl/private. $ sudo mkdir -p /etc/ssl/private Now create the local SSL certificate key and file using. In this Openssl tutorial session, I will take you through the steps to generate and install certificate on Apache Server in 8 Easy Steps. Openssl is an open source command line tool to generate, implement and manage SSL and TLS certificates. In this openssl tutorial session, we will keep your focus on SSL protocol implementation to enable secure communication between Server and Client Systems.
Use the form below to generate a self-signed ssl certificate and key. Server name: About SSL Certificates. SSL certificates are required in order to run web sites using the HTTPS protocol. For professional web sites, you usually buy such a certificate from Verisign, Thawte or any other ssl certificate vendor. SSL certificates use a chain of trust, where each certificate is signed (trusted) by. How to generate a self-signed or trusted third-party certificate using openssl: Type the pass phrase to protect the key and press [Enter] Re-enter the pass phrase. Enter the pass phrase of the private key created in Step 1. Fill in the Country Name, State or Province Name, Locality Name, Organization Name, Organizational Unit Name, Common Name. All certificates signed by the ECDSA intermediate E1 will come with a chain including an intermediate certificate whose Subject is ISRG Root X2 and whose Issuer is ISRG Root X1. Almost all server operators will choose to serve this chain as it offers the most compatability until ISRG Root X2 is widely trusted. OCSP Signing Certificate . This certificate is used to sign OCSP. openssl pkcs12 -export -in C:\TEMP\shfghdsgfh32356.crt -inkey ucc.key.temp -out ucc.pfx. Create an export password then the PFX file should now be generated to import into IIS. Using MMC > Add Snap-In > Certificates > Local Computer you can now import the PFX file into the Personal Store,you should see a key symbol on the certificate, if you do. Instead of using a root certificate for you application; this post explains why it is better to create a certificate chain containing. Generate a self signed root ssl certificate . First generate a root certificate. This certificate will be used to sign other certificates. # When asked for Common Name fill in something # like 'My Dev Certificate Authority' $ openssl req -new -x509 -extensions.

To get your own copy browse to the following link and download the Win32 OpenSSL v0.9.8y Light or Win64 OpenSSL v1.0.0k Light depending on your Windows version. Once you have installed.
An SSL certificate was required for one of our customers. The SSL certificate was to be used with a Tomcat server, but I decided to give the customer the flexibility to re-use this certificate on a different webserver if needed. This meant I used openssl to generate the certificate and then created a pkcs12 keystore Certificate Services Support. In order to create your PKCS#7 file, you must have the original certificate or .cer file. 1. Double click on the certificate .cer file to open it. 2. Click the Certification Path tab. Make sure the full chain of the certificate is showing. There should be 3 or full levels depending on the type of certificate you have Creating Certificate Signing Requests with Subject Alternate Names. Creating a CSR with Subject Alternate Names (SANs) requires creating a configuration file with the specifics. Then you call it with OpenSSL. Create a file, name.req.config: [ req ] default_bits = 2048 distinguished_name = req_distinguished_name req_extensions = req_ext [ req_distinguished_name ] countryName = Country Name (2. Creating a Certificate Signing Request (CSR) After generating your private key, create a certificate signing request (CSR) which will specify the details for the certificate. $ sudo openssl req -new -days 365 -key private.key -out request.csr. OpenSSL will ask you to specify the certificate information that have to be completed in this way
# yum install openssl. If you are using Ubuntu / Debian you can use apt-get like this: # apt-get install openssl Creating your own CA. To create your own CA you can use the script that comes with the openssl package, for this first go to an empty directory and then run the script like this 2. Create CSR for official certificate 3. Use a self signed one with hmailserver 4. Testing This is a manual of configuring and installing certificates on hMailserver (5.4) with chain. Note that you will need to have hMailserver 5.4 or higher to make use of a chain certificate. overall configuration To create a self-signed certificates, run the commands below: openssl req -newkey rsa:4096 -x509 -sha256 -days 3650 -nodes -out example.crt -keyout example.key. Details of the commands above: -newkey rsa:4096 - create a new certificate request with RSA 4096 bit. Default is 2048. -x509 - creates a X.509 Certificate
Create certificate signing requests (CSR) In the commands below, replace [digest] Use -showcerts flag to show full certificate chain, and manually save all intermediate certificates to chain.pem file: openssl s_client -showcerts -host example.com -port 443 </dev/null. Read OCSP endpoint URI from the certificate: openssl x509 -in cert.pem -noout -ocsp_uri. Request a remote OCSP responder. Create a CSR using OpenSSL & install your SSL certificate on your Apache server. Use the instructions on this page to use OpenSSL to create your certificate signing request (CSR) and then to install your SSL certificate on your Apache server Create a self-signed certificate with OpenSSL. The commands below and the configuration file create a self-signed certificate (it also shows you how to create a signing request). Note: The Common Name (CN) is deprecated - the hostname will be matched against available names in the Subject Alternate Name (SAN) field. So enter the main hostname as CN and list it together with the rest of your.
This will create a .key file in the folder that we just created. When this process is done, we can delete the original keypair file: rm keypair.key Step 3: Creating a Certificate Signing Request (CSR) File. With the key, we can create a special .csr file that we can either sign ourselves or submit to a Certificate Authority. It's. PKCS#12 (also known as PKCS12 or PFX) is a binary format for storing a certificate chain and private key in a single, encryptable file. PKCS#12 files are commonly used to import and export certificates and private keys on Windows and macOS computers, and usually have the filename extensions .p12 or .pfx. What is OpenSSL? OpenSSL is a very useful open-source command-line toolkit for working. When I have tried to use the cert import command I get the message Private key must be accompanied by certificate chain. I generated the key with openssl and created a pkcs12 file with openssl as well. I saw in another post that openssl pkcs12 isn't compatible with OpenAS2 but the answer was vague. I have tried the following: openssl pkcs12 -> keytool import openssl pkcs12 -> cert. If we are curious, we can inspect the certificates returned by the client with OpenSSL using the x509 command: openssl x509 -in 0001_chain.pem -noout -text. Enter fullscreen mode. Exit fullscreen mode. Alas, we will discover, as described above, that Let's Encrypt has signed our certificate with a SHA256 signature OpenSSL will generate 2 files which consist of a private key and a public key. Even though most people refer to an SSL/TLS certificate in the singular sense, it is the combination of the private key and the public key that makes a certificate. Before running the OpenSSL command to generate a self-signed certificate, I'm going to create a.
cert-chain.pem: the generated certificate chain which is used by istiod; root-cert.pem: the root certificate; You can replace cluster1 with a string of your choosing. For example, with the argument cluster2-cacerts, you can create certificates and key in a directory called cluster2 EFT supports full certificate chains, which is a single file with a combination of all certificates in the chain. Usually, you will receive this file from a signing authority. Otherwise, you can create the chain manually, as described below, or ask the Globalscape Technical Support team to create one for you Create a text file named myserver.cnf (where myserver is supposed to denote the name/FQDN of your server) with the following content: # OpenSSL configuration file for creating a CSR for a server certificate # Adapt at least the FQDN and ORGNAME lines, and then run # openssl req -new -config myserver.cnf -keyout myserver.key -out myserver.csr.
