Re: patent issues on keyed MD5?

[colin@nyx10.cs.du.edu (Colin Plumb)]

A possible easy way around (that is cryptographically equivalent) is to
key the initial seed values for MD5 or SHA instead of filling the first
block with key data.

IF the value you add to the default MD5 initial seed values happens to be
the result of Md5Transform on the key data, so what.  It's a pseudo-random
function.  It doesn't matter what you give it as input, as long as it's
well distributed.
