Args: data (byte string/byte array/memoryview): Optional. The very first chunk of the message to hash. It is equivalent to an early call to :meth:`BLAKE2s_Hash.update`. digest_bytes (integer): Optional. The size of the digest, in bytes (1 to 32). Default is 32. digest_bits (integer): Optional and alternative to ``digest_bytes``. The size of the digest, in bits (8 to 256, in steps of 8). Default is 256. key (byte string): Optional. The key to use to compute the MAC (1 to 64 bytes). If not specified, no key will be used. update_after_digest (boolean): Optional. By default, a hash object cannot be updated anymore after the digest is computed. When this flag is ``True``, such check is no longer enforced.
