DESCRIPTION
Pretty Curved Privacy (pcp1) is a commandline utility which can be used
to encrypt files. pcp1 uses elliptic curve cryptography for encryption
(CURVE25519 by Dan J. Bernstein). While CURVE25519 is not a worldwide
to encrypt files. pcp1 uses eliptc curve cryptography for encryption
(CURVE25519 by Dan J. Bernstein). While CURVE25519 is no worldwide
accepted standard it hasn't been compromised by the NSA - which might be
better, depending on your point of view.
Caution: since CURVE25519 is not an accepted standard, pcp1 has to be

Caution: since CURVE25519 is no accepted standard, pcp1 has to be
considered as experimental software. In fact, I wrote it just to learn
about the curve and see how it works.
Beside some differences it works like GNUPG. So, if you already know how
to use gpg, you'll feel almost at home.
