Thread: Finding Algo/Hash Type
Post: RE: Finding Algo/Hash Type
| It's not open source, but it's free to use.
Note also that I've removed the hashes from your post - posting full hashes with non-known plains is against the forum rules. |

Thread: Finding Algo/Hash Type

| No, --force would have no effect on not skipping a given platform. Only -D and -d will do that. |

Thread: md5($salt1,password,$salt2) ?
Post: RE: md5($salt1,password,$salt2) ?
| That should be irrelevant. Only how special characters (like "?") are escaped on the OS-native command line (not a hashcat issue) should vary between the platforms. |
