基于CryptoNote的加密货币的原生密码库

简介

原生密码库旨在为C/C++提供基于Rust的加密实现。目前，该库已实现了cryptonote基金会在其参考币锻造代码库中提供的所有哈希函数。

现在这个库提供了以下接口

1. 哈希
   Hash::slow -> cn_slow_hash
   Hash::fast -> cn_fast_hash
   Hash::check_with_difficulty -> cryptonote::check_hash

2. Chacha（带有ChachaKey，ChachaIV生成器）
   Chacha::generate -> chacha8

3. 密钥
   Key::generate_private_key -> generate_private_key
   Key::secret_to_public -> secret_key_to_public_key
   Key::generate_key_pair -> generate_keys
   Key::check_public_key -> check_public_key
   Key::generate_key_derivation -> generate_key_derivation
   Key::derive_public_key -> derive_public_key
   Key::underive_public_key -> underive_public_key
   Key::derive_secret_key -> derive_secret_key
   Key::generate_signature -> generate_signature
   Key::check_signature -> check_signature
   Key::generate_key_image -> generate_key_image

4. 环
   Ring::generate_signature -> generate_ring_signature Ring::check_signature -> check_ring_signature

5. 标量
   EllipticCurveScalar::random -> random_scalar
   EllipticCurveScalar::check -> check_scalar
   EllipticCurveScalar::to_hash -> hash_to_scalar
   EllipticCurveScalar::from_hash -> hash_to_ec
   EllipticCurvePoint::from_hash -> hash_to_point

用法

用法可以在测试中找到。

    // 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());
