   The documentation on DIGEST() (in UniData) is as follows:
   DIGEST
   Syntax
   DIGEST(algorithm, data, dataLoc, result)
   Description
   The DIGEST function generates a message digest of supplied data. A message
   digest is the result of a one-way hash function (digest algorithm) performed
   on the message. Message digest has the unique properties that alight change
   in the input results in a significant difference in the resulting digest.
   Therefore, the probability of two different messages resulting in the same
   digest (collision) is very unlikely. It is also virtually impossible to
   reverse to the original message from a digest. Message digest is widely used
   for digital signatures and other purposes.
   The desired digest algorithm is specified in algorithm. UniData supports the
   MD5 (Message Digest 5, 128-bit) and SHA1 (Secure Hash Algorithm 1, 160-bit)
   algorithms. You specify data and its location are with data and dataLoc,
   respectively.  UniData puts the arrived digest into a dynamic array in
   result. Since digest is short and has a fixed length, it is always put into
   a string, and no file option is provided. The result can be in either binary
   or hex format.
   Parameters
   The following table describes each parameter of the syntax.
   Parameter.....
   Description.....................................................
   algorithm       A string containing the digest algorithm name
                   (either bMD5b or bSHA1b).
   data            Data or the name of the file containing the data to be
   digested.
   dataLoc         1 - Data in a string
                   2 - Data in a file
   result          A string to store the digest result.
   The following table describes the status of each return code.
   Return Code.    Status
   0               Success
   1               Unsupported digest algorithm
   2               The data file cannot be read
   3               Message digest cannot be obtained
   4               Invalid parametersdata.
   I can't be certain, but, Rex Gozar supplied a straightforward example of
   what you appear to be looking for.
   HTH,
   Bill

I know someone already mentioned it but since there are so many
responses trying to do something more difficult I figured I'd throw it
out there again.

Won't the DIGEST() function do what you're looking for?

Thanks. These seem to only handle symmetrical encryption, not one-way
hashing
(like MD5), but maybe I am missing something. Still reading...!

I'm only aware of RC5 and some des. See ENCRYPT function in Basic Ref.

Does anyone know how to cause MD5 hashing in Universe? UV 10.2.3 on
Win2003
server. I am hoping for a Basic command that I can run on a desired
piece of
data. Reading documentation so far hasn't helped, am I wanting to do
something
that is not available to me?

Thanks in advance!
