However, this looks like a hex-encoded raw MD5 hash. Out of the box, John supports only FreeBSD-style MD5-based crypt(3) hashes, which are very different. Hex-encoded raw MD5 support for John is available with a contributed patch - or you can just use the jumbo patch which includes this functionality too. > I also tried: > > login: username hash:97c8e6d0d14f4e242c3c37af68cc376c > > And > > hash:l97c8e6d0d14f4e242c3c37af68cc376c These are wrong. > I'm using the OS X version of John if that matters. Well, you'll need to pick the source code distribution plus a suitable patch (either the raw MD5 support patch or the jumbo patch) and build from source (with the macosx-... "make" target that matches your system). P.S. You do not need to specify the "--format" explicitly. In fact, it's better to not do that, letting John autodetect the hash type for you (out of ones supported in the given build of John). This option should only be used when there are multiple hash types present in the password file(s) that you pass to John. -- Alexander Peslyak <solar at openwall.com> GPG key ID: B35D3598 fp: 6429 0D7E F130 C13E C929 6447 73C3 A290 B35D 3598 http://www.openwall.com - bringing security into open computing environments Was I helpful?
