Fides

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

Usage

In your Cargo.toml:

```

[dependencies] fides = "2.0.0"

```

In your module:

```

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

```

API

Hashing

``` let bytes: Vec;

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

ChaCha20Poly1305

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

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

let plain: Vec = decrypt(&key, &cipher); ```

Ed25519

``` let privkey: [u8;32] = ed25519::privatekey();

let pubkey: [u8;32] = ed25519::publickey(&priv_key);

let signature: [u8; 64] = sign(&message, &privkey, &pubkey); ```

x25519

``` let privkey: [u8;32] = x25519::privatekey();

let pubkey: [u8;32] = x25519::publickey(&priv_key);

let sharedsecretkey: [u8;32] = x25519::sharedkey(&privkey, &otherpartypub_key);

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

Merkle Tree

``` let objects: Vec>;

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