[ic] Usertag encrypt

[Ed LaFrance]

Here is another goodie for the community -

Usertag encrypt - for the encryption of arbitrary data within Interchange 
catalog pages, for emailing, database storage, etc.  Just think of all the 
fun you could have, playing secret agent man :-)

- Ed L.

P.S. Best installed at the server level.  Might work at the catalog level 
if the catalog in question is listed in AllowGlobal in interchange.cfg, but 
I have not tried it.

Usertag encryp  Documentation <<EOD

usage: [encrypt cmd='/usr/bin/encryptprog -opts key'*]Stuff to 
encrypt[/encrypt]

* = optional parameter

Allows the encryption of arbitrary data.  The [encrypt][/encrypt] pair can
be surrounded with [seti name][/seti] to store the results in a scratch 
variable,
written to a database field, emailed etc. The cmd parameter is optional and
can be used to specify a encryption command specifically for use with this tag;
otherwise the value from the EncryptProgram or PGP catalog directives will
be used.
