Since I know that these are md5 format, I used --format=md5
option in john.
Unfortunately, I’m getting Unknown ciphertext format name requested
error.
wolf@linux:~$ john --format=md5 md5hash.txt Unknown ciphertext format name requested wolf@linux:~$ wolf@linux:~$ john --format=md5 md5hash_only.txt Unknown ciphertext format name requested wolf@linux:~$
I’ve verified that the format is similar with pentestmonkey cheat-sheet
Any idea what’s wrong here?
