This crate provides a fast replay cache for detecting Sphinx packet replays
and is intended to be used with my Sphinx cryptography crate which you can find here:

* https://crates.io/crates/sphinxcrypto


NOTE: If you are unfamiliar with the Sphinx cryptographic packet format then you can read the Sphinx paper,
**Sphinx: A Compact and Provably Secure Mix Format** by George Danezis and Ian Goldberg.
See https://cypherpunks.ca/~iang/pubs/Sphinx_Oakland09.pdf
