what sphinx?
------------

Sphinx is a mixnet packet format.
Read the Sphinx paper:

**Sphinx: A Compact and Provably Secure Mix Format**
by George Danezis and Ian Goldberg

- http://www0.cs.ucl.ac.uk/staff/G.Danezis/papers/sphinx-eprint.pdf

status
------

This package is binary compatible with the python library:

- https://github.com/david415/sphinxmixcrypto

Although the two libraries are binary compatible and share test vectors to prove it,
go-sphinxmixcrypto is still a work-in-progress and does not yet have full feature
parity. In particular the client's use and creation of SURBs has not yet been written,
nor has the Nymserver's cryptographic components.

dependencies
------------

You can see a list of dependencies on godocs:

- https://godoc.org/github.com/david415/go-sphinxmixcrypto?imports

Currently this library depends on my own LIONESS wide block cipher implementation:

The other external dependencies include:

- https://git.schwanenlied.me/yawning/chacha20
- https://github.com/minio/blake2b-simd
