Implementations

impl Sha256

pub fn hash(input: &[u8]) -> [u8; 32]

Digest input in a single operation.

pub fn new() -> Self

Create a new context for incremental hashing.

pub fn update(&mut self, input: &[u8])

Hash the contents of input.

pub fn digest(self) -> [u8; 32]

Finish the hashing and return the digest.
