** MD5(Class)

A class to implement MD5 Message-Digest Algorithm by RSA Data
Security, Inc., described in RFC1321.

SuperClass: Object

Class Methods:

   new([str])
   md5([str])

	creates a new MD5 object.  If a string argument is given, it
        is added to the object. (see update.)

Methods:

   clone

	copies the MD5 object.

   digest

	returns have value of the added strings as a 16 bytes string.

   hexdigest

	returns have value of the added strings as an 32 bytes ASCII
	string. This method is equal to:

	def hexdigest
	  ret = ''
	  digest.each_byte {|i| ret << sprintf('%02x', i) }
	  ret
	end

   update(str)

	Update the MD5 object with the string.  Repeated calls are
	equivalent to a single call with the concatenation of all the
	arguments, i.e. m.update(a); m.update(b) is equivalent to
	m.update(a+b).
