This module implements the blake2b password hashing algorithm, bug-for-bug
compatible with the classic OpenBSD implementation. It is not recommended except
in cases of backwards-compatibility with legacy systems.
This is a low-level module which implements cryptographic primitives. Direct use
of cryptographic primitives is not recommended for non-experts, as incorrect use
of these primitives can easily lead to the introduction of security
vulnerabilities. Non-experts are advised to use the high-level operations
available in the top-level crypto module.
Be advised that Hare's cryptography implementations have not been audited.
fn blake2b(key: u8, sz: size) digest;
Creates a hash::hash which computes a BLAKE2b hash with a given key and a
given hash size. The size must be between 1 and 64, inclusive. If this
function is used to hash sensitive information, the caller should call
hash::close to erase sensitive data from memory after use; if not, the
use of hash::close is optional. This function does not provide reset
functionality and calling hash::reset on it will terminate execution.
