OK.

The functions in hex-util.el are used by hmac-md5.el, sasl-cram.el,
sasl-digest.el, and sha1.el in Gnus CVS.  Further, at least rfc2104.el
contain re-implementation of the functionality in hex-util.el.
Changing the calls in hmac-md5.el and sasl*.el to call sha1 functions
seem wrong.

Is there a "hex" coding system, or some more native way to hex encode
some data?

If not, I believe hex-util.el do make sense.
