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?
