Function orion::default::hmac

pub fn hmac(
    secret_key: &[u8], 
    data: &[u8]
) -> Result<Vec<u8>, UnknownCryptoError>

HMAC with SHA512.

Exceptions:

An exception will be thrown if:

• The length of the secret key is less than 64 bytes

Note:

The secret key should always be generated using a CSPRNG. The gen_rand_key function in util can be used for this.

Usage example:

use orion::default;
use orion::core::util;

let key = util::gen_rand_key(64).unwrap();
let msg = "Some message.".as_bytes();

let hmac = default::hmac(&key, msg).unwrap();
