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.
