The f5mku utility: Reference

The
f5mku
utility is a cryptographic tool for managing passwords and passphrases. The available command options that display when you type
f5mku -h
at a system prompt are listed below.
F5 recommends not using the f5mku utility on a BIG-IQ system.
F5 strongly recommends that you avoid using the
-r
option to reset a master key. Using
-r
without first decrypting the passwords or passphrases on configuration objects will cause any subsequent configuration load operation to fail. Use the TMOS Shell (
tmsh
) command
modify /sys master-key prompt-for-password
instead.
