BEGIN PGP PUBLIC KEY BLOCK (Alice and Bob worked for the NSA all along) is a recording of a PGP Key – specifically my Public Key, which is what the part of the key shared with other people so that they can encrypt emails sent to me. The track's format is based on that of number stations, cryptic Cold War shortwave broadcasts commonly attributed to espionage. In particular, it uses the call sign of the Lincolnshire Poacher.
