Cryptography Primitives For CryptoNote Based Crypto Currencies

Usage

  1. Cryptonote Chacha8 functions.

a. Generate ChachaKey use cryptonote_crypto::chacha::{ChachaKey}; let key = ChachaKey::generate(String::from("")); let key = ChachaKey::generate(String::from("your password"));

b. Generate Chacha let iv = ChachaIV::new(); let chacha = Chacha::new(key, iv);

c. Cipher a plaintext let plain = *b"hello world!"; let cipher = chacha.encrypt(&plain[..]); let cipher1 = chacha.encrypt(&cipher[..]); assert!(plain == cipher1.as_slice());

  1. Slow Hash

```

use cryptonotecrypto::hash; // Version 6 let a = b"hello world!"; let hash = hash::cnslow_hash(&a[0..], hash::HashVersion::Version6);

// Version 7 // a must be a bytestring with more than 64 bytes long let a = bytestring::stringtou8array("0707cff699d605f7eb4dbdcad3a38b462b52e9b8ecdf06fb4c95bc5b058a177f84d327f27db739430000000363862429fb90c0fc35fcb9f760c484c8532ee5f2a7cbea4e769d44cd12a7f201"); let hash = hash::cnslow_hash(&a[0..], hash::HashVersion::Version7); ```

  1. Fast Hash

use cryptonote_crypto::hash; let a = b"hello world!"; let hash = hash::cn_fast_hash(&a[0..]);
