I'm not a C programmer, but I hacked the 'gb.crypt' source ('c_crypt.c'):
- strcpy(key, "$1$");
+ strcpy(key, "$6$");
I compiled this:
./reconf
./configure
make
and I installed the created 'gb.crypt.so.0.0.0'.
The result:
Exec ["mkpasswd", "-m", "sha-512", "alma", "almaalma"]
Print Crypt.MD5("alma", "almaalma")
Output:
$6$almaalma$MWWhHTP9sVVxJ1olWCRidzfMOSH0nOKVR9cjcHCtqP5LQ/08V18jiwakTNxWSNUWMyIE2lVLKBL.MUBTk460T.

So this method is works, the generated hash is a SHA-512 hash.
Please implement this little plus function, really don't seem too
difficult. :-)
