We are looking at implementing support for 256-bit AES encryption of passwords/password phrases.
This note was pointed out to me:
Important! A security file that has 256-bit AES encryption enabled cannot be shared with CA Top Secret r15 (and earlier) systems. If you want 256-bit AES encryption while sharing the file, ensure that all shared systems are at least Version 16.
I don't think our production and test LPARs share files. The only sharing I'm aware of is via CPF (the password propagation).
Should we wait until all LPARs are converted to r16, or can we implement the 256-bit AES encryption in test with r16 before we have upgraded production to R16?
