Subject: DES crypt hashes containing commas

Alexander,

I was wondering if you could comment on the following code from
DES_std.c:

        if (ciphertext[13]) return DES_atoi64[ARCH_INDEX(ciphertext[5])] |
                ((ARCH_WORD)DES_atoi64[ARCH_INDEX(ciphertext[6])] << 6) |
                ((ARCH_WORD)DES_atoi64[ARCH_INDEX(ciphertext[7])] << 12) |
                ((ARCH_WORD)DES_atoi64[ARCH_INDEX(ciphertext[8])] << 18);

Specifically, what are these hashes with commas at the end, and what
is the stuff after the commas for?  It looks like something salt and
something rounds?
