Package-Level Functions (total 2)


	
		New returns a new hash.Hash computing the MD5 checksum. The Hash also
		implements encoding.BinaryMarshaler and encoding.BinaryUnmarshaler to
		marshal and unmarshal the internal state of the hash.


	
		Sum returns the MD5 checksum of the data.




Package-Level Constants (total 2)


	
		The blocksize of MD5 in bytes.


	
		The size of an MD5 checksum in bytes.
