Rust Implementation of the PSP Security Protocol

Google have released the PSP (PSP Security Protocol) specification and a reference implementation. That implementation is in C.

The psp_security crate is a Rust port of the reference implementation. It implements PSP encrypt/decrypt functionality using Rust for memory safety.

The implementation consists of a core psp_security library which implements the PSP packet encapsulation, decapsulation, encryption and decryption and also a command line utility that uses this library. This utility is useful for generating test vectors, and encrypting / decrypting content from the command line.
