Auditor asked how passwords are stored in Top Secret Database.
Which hash algorithm is used?
Release : 16.0
Component : CA Top Secret for z/OS
The Top Secret AES algorithm performs thousands of hash operations against the password and random text to generate a key that encrypts the password.
The TSS encryption algorithm uses the CP (central processor) assist for Cryptographic Functions (CPACF) to perform SHA-256 operations.
When the CPACF is not available (older processors such as z900, z800,z990, z890), SHA-256 is performed in software.
