Charset descrypt / crypt(3) - Non-printable password? - root2 - 11-29-2016 Hi, I try to find a preimage of a crypt(3) aka "descrypt" hash. I did a bruteforce of 1-8 char length with all 95 printable ASCII characters, but no luck. I now assume that the password consists of non-printable characters, too. While the mask: Code: ?b?b?b?b?b?b?b?b searches from 0x00 to 0xFF (256 values) I only need 0x00 to 0x7F (128 values) as crypt(3) is limited to this keyspace. https://linux.die.net/man/3/crypt How to build such a charset? Currently, my crypt3.hcchr looks like this, is it correct? Code: user@pc:~# cat crypt3.hcchr (A single line, no line breaks at the end) I start hashcat like this Code: ./hashcat64.bin -a 3 -m 1500 --session=mysession myhash.lst --hex-charset --custom-charset1=charsets/crypt3.hcchr masks/mymask.hcmask -o found.cracked RE: Charset descrypt / crypt(3) - Non-printable password? - atom - 11-29-2016 You must have some nice setup over there if you searched through that keyspace. On my 3x1080 I'd expect that to take around a month to finish. Anyway the charset looks good.
