Certificate Signing Request (CSR) Generation Instructions - SonicWall SSL Offloaders



This document provides Certificate Signing Request (CSR) Generation instructions for SonicWall SSL Offloaders. If you are unable to use these instructions for your server, GeoTrust recommends that you contact the server vendor or the organization, which supports SonicWall SSL Offloaders.

To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file or your password and generate a new one, your SSL Certificate will no longer match and a replacement has to be made.

Generate a Private Key and CSR

NOTE: A key length of 1024 bit is the default, but GeoTrust recommends the use of a 2048 bit key.

  1. Create a directory called ‘C:\test’.
  2. Launch “OpenSSL”.
  3. Enter the following command to create a private key.
    genrsa -des3 -out c:\test\key.pem 2048

  4. Enter in a passphrase to protect the key (at least six characters).
  5. Enter the following command to create a certificate request:
    req –new –key c:\test\key.pem –out c:\test\req.pem –config openssl_config.txt 

  6. Enter in all the required fields for the certificate you want to generate.
  7. You have just created a key pair and a CSR.
  8. To copy and paste the information into the enrollment form, open the file in a text editor that does not add extra characters (Notepad or Vi are recommended).
  9. Verify your CSR with the GeoTrust CSR Checker
  10. Copy and paste the CSR into the enrollment pages on the GeoTrust website
