Subject: --subformat for crypt(3)
I just uploaded patch 0020 to the wiki. This one enables use of
--subformat to the generic crypt(3) format, for choosing what type to
benchmark (the default is DES).
$ ./john -test -fo:crypt
Benchmarking: generic crypt(3) [?/64]... DONE
Many salts: 226560 c/s real, 226560 c/s virtual
Only one salt: 228576 c/s real, 228576 c/s virtual
$ ./john -test -fo:crypt -sub=sha512
Benchmarking: generic crypt(3) [?/64]... DONE
Many salts: 238 c/s real, 238 c/s virtual
Only one salt: 238 c/s real, 238 c/s virtual
Now we can see OMP scaling for non-DES hashes too:
$ ./john -test -fo:crypt -sub=sha512
Benchmarking: generic crypt(3) [?/64]... (2xOMP) DONE
Many salts: 448 c/s real, 224 c/s virtual
Only one salt: 448 c/s real, 225 c/s virtual
I added self-tests for MD5, SHA256 and SHA512. This works fine even if
your system does not have the SHA ones (self-test will just fail if you
try to use them). More tests could be added for whatever crypt(3)
variants are out there.
