Provided examples of what your hashes.txt file might look like (though I’m sure other variations are supported that aren’t covered here yet).Copied example hashes out of the source code for most supported hash types.I thought it might be helpful to compile a cheat sheet to reduce the amount of time I spend grepping and googling. These problems can all be sorted with a bit of googling or grepping through the john source code. Sometimes I gain access to a system, but can’t recall how to recover the password hashes for that particular application / OS.This is inevitable because some hashes look identical.


These are not problems with the tool itself, but inherent problems with pentesting and password cracking in general. I’ve encountered the following problems using John the Ripper. There is plenty of documentation about its command line options.

John the Ripper is a favourite password cracking tool of many pentesters.
