This game kind of brings home how far we've come with cryptography. It is now possible for pretty much anyone to have instant access to truly unbreakable encryption. For instance, even if I spot you a few thousand years, you won't be able to get my credit card number out of this message encrypted with my public key:
-----BEGIN PGP MESSAGE-----
Version: GnuPG v2
-----END PGP MESSAGE-----
ETA: For those interested, it's encrypted with a 384-bit ECC key. The encryption was done on my private server over an 256-bit-AES-encrypted SSH session over a 256-bit AES-encrypted VPN tunnel. Both SSH and VPN authentication is via 2048-bit RSA key.
