A pure-rust implementation of the CryptoNight digest algorithm. The

implementation is based on the specification in

[CryptoNote standard 8](https://cryptonote.org/cns/cns008.txt).

The crate is compiled with support for AES CPU extensions if the

platform supports it, currently only on x86 and x86_64. It is possible

to disable this by disabling the default features.

## Features

- [`digest`](https://crates.io/crates/digest)-compatible implementation

  of the CryptoNight digest.

- No non-rust dependencies.

- Support for SSE2 and AES CPU extensions.

- Full fallback implementation for other platforms.

- Performance comparable to competing implementations.

## Compared to others

There are already different crates that also implement this digest

algorithm, but there are some differences. In decreasing order of

downloads (as of 2019-10-25):

- [cryptonight-rs](https://crates.io/crates/cryptonight-rs) simply

  wraps the function from the original Monero C code. It also claims

  to be unstable.

- [yellowsun](https://crates.io/crates/yellowsun) implements the digest

  completely in Rust but does so in a way that requires using AES CPU

  extensions. If your platform doesn't have those, you can't use it.

- [cryptonight](https://crates.io/crates/cryptonight) requires SSE (but

  not AES) extensions for the hash. It indirectly depends on some C-code

  to implement the secondary hashes.

  

Aside from the differences above, this crate is the only one that can

easily compute hashes incrementally and that can operate with the

traits in the `digest` crate.

## Wish list

- [x] Support CPU extensions for key generation

- [ ] `nostd` support
