sha256 top-level constant

BlockHashBase<BlockHashSink> const sha256

SHA-256 is a member of SHA-2 family which uses 256-bit internal state to generate a message digest of 256-bit long.

SHA-2 is a family of algorithms designed by the United States National Security Agency (NSA), first published in 2001 and later standardized in FIPS 180-4.

Implementation

const BlockHashBase sha256 = _SHA256();
