Fides

Fides is a library for hashing with blake3, asymmetric cryptography on curve 25519, symmetric cryptography with chacha20poly1305 and merkle tree functions.

Usage

In your Cargo.toml:

[dependencies]
fides = "2.1.1"

In your module:

use fides::{chacha20poly1305, ed25519, hash, merkle_root, x25519};

API

Hashing

let bytes: Vec<u8>;

let blake3_hash: [u8;32] = hash(&bytes);

ChaCha20Poly1305

let key: [u8; 32] = hash(&"password".as_bytes());

let cipher: Vec<u8> = chacha20poly1305::encrypt(&key, &msg);

let plain: Vec<u8> = decrypt(&key, &cipher);

Ed25519

let priv_key: [u8;32] = ed25519::private_key();

let pub_key: [u8;32] = ed25519::public_key(&priv_key);

let signature: [u8; 64] = sign(&message, &priv_key, &pub_key);

let verification: bool = x25519::verify(&message, &public_key, &signature);

x25519

let priv_key: [u8;32] = x25519::private_key();

let pub_key: [u8;32] = x25519::public_key(&priv_key);

let shared_secret_key: [u8;32] = x25519::shared_key(&priv_key, &other_party_pub_key);

Merkle Tree

let objects: Vec<Vec<u8>>;

let root: [u8; 32] = merkle_root(&objects);
