+OpenPGP as defined by RFC 4880 as well as some extensions (e.g., RFC 6637,
+which describes ECC cryptography) for OpenPGP.  This includes support for
+unbuffered message processing.
+
+A few features that the OpenPGP community considers to be deprecated (e.g.,
+version 3 compatibility) have been left out.  The developers have also updated
+some OpenPGP defaults to avoid foot guns (e.g., they selected modern algorithm
+defaults).
+
+This Guix package is built to use the nettle cryptographic library.")
