Setting the AES encryption key size for the PATROL Agent - Documentation for BMC PATROL Agent 10.7
Daniel Cobb 
Current version of the PATROL Agent is backward compatible with the older encryption mechanisms. By default, current version of the PATROL Agent encrypts the data in AES format. If the pre-existing data is encrypted using older encryption mechanism, such as DES, the data is decrypted and re-encrypted in AES format in the current version.
