Digital signatures and Certificates

Who is TryHackMe's HTTPS certificate issued by?

E1

SSH Authentication

I recommend giving this a go yourself. Deploy a VM, like Linux Fundamentals 2 and try to add an SSH key and log in with the private key.

No answer needed

Download the SSH Private Key attached to this room.

What algorithm does the key use?

RSA

Crack the password with John The Ripper and rockyou, what's the passphrase for the key?

run ssh2john idrsa.id_rsa > id.txt and than john --wordlist=/Path/to/wordlist.txt id.txt to get the passphrase and the answer.
