Fides

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

Features

• Blake3 Hashing.
• 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 = encrypt(&key, &msg);

```

Symmetric Decryption ```

use fides::chacha20poly1305::decrypt;

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

```

Asymmetric Private Key Generation ```

use fides::Ed25519::private_key;

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

```

Asymmetric Public Key Generation ```

use fides::Ed25519::public_key;

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

```

Asymmetric Shared Key Generation ```

use fides::x25519::shared_key;

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

```

Asymmetric Message Signing

```

use fides::Ed25519::sign;

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

```

Asymmetric Message Verification

```

use fides::Ed25519::verify;

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

```
