raw-crypto Library For CryptoNote Based Crypto Currencies

Intro

Raw Crypto Library is to provide crypto implementations in C/C++ with rust. Currently the library has implemented all hash functions provided by the cryptonote foundation in it's referential coin forging code base.

Now this library provide the follow interfaces:

1. Hash
   Hash::slow -> cnslowhash
   Hash::fast -> cnfasthash

2. Chacha(with ChachaKey, ChachaIV generators)
   Chacha::generate -> chacha8

3. Key
   Key::generateprivatekey -> generateprivatekey
   Key::secrettopublic -> secretkeytopublickey
   Key::generatekeypair -> generatekeys
   Key::checkpublickey -> checkpublickey
   Key::generatekeyderivation -> generatekeyderivation
   Key::derivepublickey -> derivepublickey
   Key::underivepublickey -> underivepublickey
   Key::derivesecretkey -> derivesecretkey
   Key::generatesignature -> generatesignature
   Key::checksignature -> checksignature
   Key::generatekeyimage -> generatekey_image

4. Ring

Ring::generatesignature -> generateringsignature Ring::checksignature -> checkringsignature

1. Scalars
   EllipticCurveScalar::random -> randomscalar
   EllipticCurveScalar::check -> checkscalar
   EllipticCurveScalar::tohash -> hashtoscalar
   EllipticCurveScalar::fromhash -> hashtoec
   EllipticCurvePoint::fromhash -> hashto_point

Usage

Usage can be found in tests.

``` // Generate key let key = ChachaKey::generate(String::from(""));

// Generate iv
let iv = ChachaIV::from([0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18]);

// Generate chacha object
let chacha = Chacha::new(key, iv);

// Prepare plain text
let plain = *b"hello world!";

// Encrypt with chacha8
let cipher = chacha.encrypt(&plain[..]);

// Encrypt again will get the original plain text
let recipher = chacha.encrypt(&cipher[..]);

// they should be equal
assert!(plain == recipher.as_slice());

```
