• ChaCha20Poly1305 Encryption.
• ChaCha20Poly1305 Decryption.
• Ed25519 Private Key Generation.
• Ed25519 Public Key Generation.
• Ed25519 Message Signing.
• Ed25519 Message Verification.
• x25519 Private Key Generation.
• x25519 Public Key Generation.
• x25519 Shared Key Generation.

Usage

In your Cargo.toml:

[dependencies]
fides = "2.0.0"

API

Hashing

use fides::hash;

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

Symmetric Encryption

use fides::chacha20poly1305::encrypt;

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

Symmetric Decryption

use fides::chacha20poly1305::decrypt;

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

Asymmetric Private Key Generation

use fides::Ed25519::private_key;

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

Asymmetric Public Key Generation

use fides::Ed25519::public_key;

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

Asymmetric Shared Key Generation

use fides::x25519::shared_key;

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

Asymmetric Message Signing

use fides::Ed25519::sign;

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

Asymmetric Message Verification

use fides::Ed25519::verify;

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