You've managed to intercept two transmissions from other space ships - each contains a password-protected archive and a ciphertext. They look like packages from the server that corrects autopilot configuration settings to avoid space garbage. Unfortunately, you can't communicate with this server. Apparently, both ciphertexts are actually the same message encrypted with different RSA public keys. As for the message, it might be the key for archive. Knowing the source of both transmissions, you do have public keys that might be used to encrypt the archive key. Is it possible to get the content of the archive? You will get the space junk out of your way!
