Thread: md5(md5($pass).$salt)
Post: RE: md5(md5($pass).$salt)
| This is the algo used by vbulletin, see the --help output:
hashcat supports:
-m 2611 = vBulletin < v3.8.5
and
-m 2711 = vBulletin >= v3.8.5
the difference is mainly the supported salt length (s... |

Thread: MD5: Need Advice
Post: RE: MD5: Need Advice
| well, you could just use -m 3710 = md5($salt.md5($pass)) together with --hex-salt (because you said that the first MD5 is in binary not hex), an example (hashes mask with xxxx):
Code:

Thread: MD5: Need Advice
Post: RE: MD5: Need Advice
| If you are sure that the algorithm is:
md5_hex(md5($salt) . md5_hex($pass))
... where md5 (x) is the binary/raw output and md5_hex (y) is the hexadecimal output...
then it should work.
just try it... |

Thread: MD5: Need Advice
Post: RE: MD5: Need Advice
| Well, I guess if we agree that the algorithm is MD5(MD5_raw ($salt) . MD5_raw ($pass)) you could convert those hashes to just MD5 ($salt_new . MD5_raw ($pass)) where $salt_new is the precomputed MD5 d... |

| a, b, c, d, 0x80 and the remaining buffers are all 0 (that should be very obvious if you think about it, it must get shorter if we do not use hex but binary instead, it will be halved i.e. 32/2 = 16).... |
