You are in: IBM i Technology Updates > IBM i Security > SHA512 password encryption scheme (QPWDLVL 4)
The new password levels use Password-based Key Derivation Function 2 (PBKDF2) with HMAC SHA512
(SHA-2 512 bit) encryption for the scheme.
(SHA-2 512 bit) encryption for the scheme.
New Password Level (QPWDLVL) system value (4)
- When the system is changed to password level 4, the DES (password level 0/1) and SHA-1 (password level 2/3) passwords are removed from the user profile.
- For more information, see the Planning password level changes topic in IBM Documentation.
New System Service Tools (SST) password level 3
- Used for service tools user ID passwords
- For more information, see the Encryption for service tools user ID passwords topic in IBM Documentation.
