NimbostratusSHA512 iRule to create the same hash as used in the local user database
Hi, I'm scratching my head here having run out of avenues to go down. I am trying to write an iRule which will take the BASIC auth password from an HTTPS request and create a hash to compare against ...

NimbostratusYou have generated a single SHA512 hash from the password (and salt). However the OS uses (by default) 5000 rounds to generate the password.

NimbostratusThanks for answering my query Ronald. I have presumed that the SHA512 hash function carries out the 5000 rounds by default for me before returning the hash but I will experiment with a loop to simulate the rounds.
I think a related issue that I have is that the base64 encode is different on the F5 passwords to the standard b64encode in the iRule. The hash from the standard b64encode seems to use a '/' and a '+' as the extra 2 characters whereas the password hashes stored on the F5 use a '/' and a '.' instead.
