Functions
hash
pub external fn hash(HashAlgorithm, BitString) -> BitString
Computes a digest of the input binary.
secure_compare
pub fn secure_compare(left: BitString, right: BitString) -> Bool
Compares the two binaries in constant-time to avoid timing attacks.
For more details see: http://codahale.com/a-lesson-in-timing-attacks/
strong_random_bytes
pub external fn strong_random_bytes(Int) -> BitString
Generates N bytes randomly uniform 0..255, and returns the result in a binary.
Uses a cryptographically secure prng seeded and periodically mixed with operating system provided entropy. By default this is the RAND_bytes method from OpenSSL.
