type state[link]

type state = struct {
	hash::hash,
	h: [8]u32,
	x: [BLOCKSIZE]u8,
	nx: size,
	ln: size,
};

def BLOCKSIZE[link]

def BLOCKSIZE: size;

The internal block size.

def SIZE[link]

def SIZE: size;

The size, in bytes, of a SHA-256 digest.

fn sha256[link]

fn sha256() state;

Creates a hash::hash which computes a SHA-256 hash. 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.
