Profanity65

Anyone can use PGP to make their e-mail more secure. Using a pair of public and private keys, you either encrypt the entire message for a user, or add a signature to your e-mail for others to verify that it is your original content.

Unfortunately, PGP signatures usually look kinda boring:

-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.15 (Darwin)

Let's make them more interesting!

Concept

profanity.json includes a list of swears which map to valid PGP characters, a-z, A-Z, 0-9, +, /, and =

Using OpenPGP.js, messages are encrpyted or signed using the same globally-trusted GPG client. Then Profanity65 replaces the message's characters with a much more profane system:
