Package saltpack is an implementation of the saltpack message format. Saltpack is a light wrapper around Dan Berstein's famous NaCl library. It adds support for longer messages, streaming input and output of data, multiple recipients for encrypted messages, and a reasonable armoring format. We intend Saltpack as a replacement for the PGP messaging format, as it can be used in many of the same circumstances. However, it is designed to be: (1) simpler; (2) easier to implement; (3) judicious (perhaps judgmental) in its crypto usage; (4) fully modern (no CFB mode here); (5) high performance; (6) less bug- prone; (7) generally unwilling to output unauthenticated data; and (8) easier to compose with other software in any manner of languages or platforms.
