In an ancient tomb, under tons of cob webs, we found this bygone system. It seems to be running SSH, but all we get is "Protocol major versions differ: 2 vs. 1".

Next to it there was a floppy disk containing age-old artifacts.

There were people that could talk to this thing?! Looks like somebody recorded their conversation with the system, as well as the first 512 plain text bytes that were fed into cipher_encrypt() on the client.

Can you find a way to decipher the rest of the conversation?
