SHA-256 and SHA-512 based encryption algorithms support passing number of hashing rounds in the salt string, like:
crypt("password", "$5$rounds=100000$saltsaltsalt")
This was present since introduction of SHA-*-based algorithms in the glibc commit c3266dc0d85ed519ff40d1738aadf7b1280af3ba.
The parameter is explained. Minor wording and formatting fixes done.
Konstantin Shemyak (4):
crypt.3: wfix: encryption is not done with SHA-xxx, but with a
function based on SHA-xxx.
crypt.3: ffix: added missing formatting
crypt.3: wfix: clarified that ending of the salt string with '$' is
optional
crypt.3: Added description of previously undocumented 'rounds'
parameter
