SHA-256 and SHA-512 based encryption algorithms support passing number of
hashing rounds in the salt string, like:
crypt("password", "$5$rounds=100000$saltsaltsalt")
This was present since introduction of SHA-*-based algorithms in the
glibc commit c3266dc0d85ed519ff40d1738aadf7b1280af3ba.
The parameter is explained. Additional minor corrections done.
Patch 2/4 from the series reported as "applied" in the first version is
not re-sent.
Konstantin Shemyak (3):
crypt.3: encryption is not done with SHA-xxx, but with a function
based on SHA-xxx
crypt.3: clarified that ending of the salt string with '$' is optional
crypt.3: added description of previously undocumented 'rounds'
parameter
