We installed the latest Linux 11.4 Agent version and received the error below when job is submitted to the agent;

cybermation.library.communications.CybConversationException: Illegal block size
CA Workload Automation Agent 11.4
CA Workload Automation EE (ESP Edition) 11.4
Mismatch agent's AES encryption key with the EE (ESP) scheduler.

Error in agent's transmitter log like below;

Caused by: javax.crypto.IllegalBlockSizeException: The input was invalid: Invalid input length for decryption. Should be a multiple of the block size - 16.

You can use either of the following;
1. Use the Agent's keygen utility to set the encryption key and cipher on the agent, or
2. Copy the cryptkey.txt file from a Linux agent that is working with ESP scheduler to the agent's cryptkey.txt file location (default location is the agent installation directory).
