Generate CSR: Apache (w/OpenSSL, MODSSL, or ApacheSSL)

Follow these instructions to generate a Private Key and CSR.

You must have OpenSSL installed on your server. OpenSSL is a free, open-source tool, used from the command-line, to generate CSR's, private keys, and other cryptographic functions. In most cases OpenSSL is already installed on your operating system. To verify that you have OpenSSL installed type openssl --help from the command line. If the shell returns command not found OpenSSL is either not installed or you are not authorized to use that command. If OpenSSL is not installed on your system you may need to download OpenSSL.

Note: The examples below use the following naming conventions: "Your Private Key" = "domainname.key"; "Your Web Server Certificate" = "domainname.crt".

1. Create an RSA private key for your Apache server, with triple-DES encryption and PEM-formatted: openssl genrsa -des3 -out domainname.key 1024 You will be prompted to enter and re-enter a pass phrase. Please read the first tip below before you issue this command.
   Warning: Backup this key and its passphrase.

   Tip: If you choose to use triple des encryption, you will be prompted for the password each time you start your web server from a cold start. (When using the restart command, you will not be prompted for the password). Some of you may find this password prompt to be a nuisance, especially if you need to boot the system during off-hours. Or, you may believe that your system is already sufficiently secure. So, if you choose not to have a password prompt (hence no triple des encryption), use the command in step 2 below.

   Tip: Your private key will be created in the current directory unless otherwise specified. The private key needs to end up in the /etc/httpd/conf/ssl.key directory if you installed Apache using the RPM or /usr/local/apache/conf/ssl.key directory if you installed Apache using the source files. You can copy the private key to the proper directory or move into that directory before executing the openssl commands. Please note that 'ssl.key' is a directory that contains your 'domainname.key' file. When your GeoTrust SSL certificate is delivered it will need to be copied to /etc/httpd/conf/ssl.crt or /usr/local/apache/conf/ssl.crt directory.

2. You could also create a private key without triple-DES encryption: openssl genrsa -out domainname.key 1024 You can view the contents of the private key by using the following command: openssl rsa -noout -text -in domainname.key The private key text should begin with -----BEGIN RSA PRIVATE KEY----- and end with -----END RSA PRIVATE KEY-----.
3. Now create a Certificate Signing Request (CSR) using the RSA private key created above (output will be PEM format): openssl req -new -key domainname.key -out domainname.csr * Note: You will be prompted for your PEM passphrase if you included the "-des3" switch above.
4. You will be asked for several pieces of info which will be used by GeoTrust to create your new SSL certificate. These fields include the Common Name (aka domain, FQDN), organization, country, key bit length, etc. Use the CSR Legend in the right-hand column of this page to guide you when asked for this information. The following characters should not be used when typing in your CSR input: < > ~ ! @ # $ % ^ / \ ( ) ? , &
5. You will be prompted for extra attributes (i.e., a challenge password and optional company name); we recommend you leave these attributes empty (just hit Enter).
6. You can verify the contents of your CSR by using the following command: openssl req -noout -text -in domainname.csr
7. Save a copy of your CSR. The CSR will be needed during the online order process. You'll be asked to copy-and-paste your CSR into a special CSR box.
   
   Below is an example of what your CSR will look like. This is a example only and cannot be used to generate your SSL certificate.
