How to create an SSL CSR with a 2048 bit key
To Generate a Triple-DES Encrypted key pair and a certificate signing request (CSR) with a 2048 bit key length, firstly you will need to generate a key. For this use the following command, please make a note of the pass phrase as the key and CSR are useless without it:
openssl genrsa -des3 -out servername.key 2048
Next we will use the key to generate a CSR, using the following command:
openssl req -new -key servername.key -out servername.csr
This CSR can now be used to submit to SSL vendors to create strong certificates.
