No password hashes loaded in JohnTheRipper

I'm trying to crach ssh password with john, but there's an error, and I can't find the answer to solve it

firstly I use ssh2john.py:

python3 ssh2john.py id_rsa > id_rsa.hash

then john:

john --wordlist=/usr/wordlists/rockyou.txt id_rsa.hash

the result is:

No password hashes loaded (see FAQ)

some people say I need to write format like --format=crypt, but it also doesn't work

maybe I need to write another format... please help

Solution

  • I needed to get John from its github. /run gives all of John tools (i.m. ssh2john etc) and John itself.

    so DO NOT do just

    apt install john
