	Title		: UMAC: Message Authentication Code using Universal Hashing

This specification describes how to generate an authentication tag
   using the UMAC message authentication algorithm.  UMAC is designed to
   be very fast to compute in software on contemporary uniprocessors.
   Measured speeds are as low as one cycle per byte.  UMAC relies on
   addition of 32-bit and 64-bit numbers and multiplication of 32-bit
   numbers, operations well-supported by contemporary machines.

   To generate the authentication tag on a given message, a "universal"
   hash function is applied to the message and key to produce a short,
   fixed-length hash value, and this hash value is then xor'ed with a
   key-derived pseudorandom pad.  UMAC enjoys a rigorous security
   analysis and its only internal "cryptographic" component is a block
   cipher used to generate the pseudorandom pads and internal key
   material.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
