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:

text [dependencies] fides = "2.3.0"

In your module.rs:

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

API

Hashing

```text let object: Vec;

let object_hash = hash(&object[..]); ```

ChaCha20Poly1305

```text let message: Vec;

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

let cipher: Vec = chacha20poly1305::encrypt(&key, &message[..])?;

let plain: Vec = chacha20poly1305::decrypt(&key, &cipher[..])?; ```

Ed25519

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

let signature: [u8; 64] = ed25519::sign(&message, &priv_key);

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

let verification: bool = ed25519::verify(&message, &pub_key, &signature); ```

x25519

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

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

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

Merkle Tree

```text let hashes: Vec<[u8; 32]>;

let root = merkle_root(hashes); ```
