Question:

We are implementing XCOM SSL implementation and will be distributing the upgraded XCOM level with all SSL modules to our production systems. What is the random.pem file meant for? Is this a standard file which we can use on all LPARs without modification?
If not what actions are needed to create this file?

Answer:

The file random.pem contains a randomly-generated seed-number, which will be used after SSL-session initiation to build a randomly-generated symmetric-key, which in turn will then be used for encryption-decryption during the rest of the duration of the SSL-session.
