A program to determine what SSH keys a server accepts. See https://www.agwa.name/blog/post/whoarethey for background. Inspired by whoami.filippo.io.
If you have the latest version of Go installed, you can run:
go install src.agwa.name/whoarethey@latest
Specify the host/port of the SSH server, the username to try logging
in as, and one or more keys, which can specified as the name of an
authorized_keys-formatted file, or a GitHub username prefixed with
github::
whoarethey HOST:PORT USERNAME KEYSFILE|github:USERNAME...
The program outputs a list of the keys which were accepted by the server.
To determine if @AGWA or @FiloSottile can log in as root on 192.0.2.4:
$ whoarethey 192.0.2.4:22 root github:AGWA github:FiloSottile
github:AGWA
