…ythonGH-8346) (pythonGH-8581) * help(hashlib) didn't work because of incorrect module name in blake2b and blake2s classes. * Constructors blake2*(), sha3_*(), shake_*() and keccak_*() incorrectly accepted keyword argument "string" for binary data, but documented as accepting the "data" keyword argument. Now this parameter is positional-only. * Keyword-only parameters in blake2b() and blake2s() were not documented as keyword-only. * Default value for some parameters of blake2b() and blake2s() was None, which is not acceptable value. * The length argument for shake_*.digest() was wrapped out to 32 bits. * The argument for shake_128.digest() and shake_128.hexdigest() was not positional-only as intended. * TypeError messages for incorrect arguments in all constructors sha3_*(), shake_*() and keccak_*() incorrectly referred to sha3_224. Also made the following enhancements: * More accurately specified input and result types for strings, bytes and bytes-like objects. * Unified positional parameter names for update() and constructors. * Improved formatting.
