Values
namespace Minilib.Crypto.SHA256
digest
Type: Std::Array Std::U8 -> Std::Array Std::U8
SHA256::digest(bytes) computes SHA-256 secure hash function of bytes.
empty
Type: Minilib.Crypto.SHA256::SHA256
An empty SHA-256 hasher.
finalize
Type: Minilib.Crypto.SHA256::SHA256 -> Std::Array Std::U8
sha256.finalize retrieves a final SHA-256 hash value.
update
Type: Std::Array Std::U8 -> Minilib.Crypto.SHA256::SHA256 -> Minilib.Crypto.SHA256::SHA256
sha256.update(bytes) processes bytes, and updates its internal state.
