CRYPTXOR - a sample runtime loadable encryptor.
------------------------------------------------------------------------

WinPMail v2.20 and later supports the idea of "Runtime-Loadable
Encryptors" - modules that allow third parties to add their own
encryption products seamlessly into Pegasus Mail. For more information on
the interface, consult the CRYPTIF.TXT file in the FORMS subdirectory of
your WinPMail install directory.

CRYPTXOR is a sample of how one might write a runtime-loadable encryptor,
provided in full source code form. CRYPTXOR.C is the shell of the module,
essentially a simple WinPMail Extension. ENCRYPT.C contains the actual
exported encryptor functions that implement the interface described in
CRYPTIF.TXT.

**** WARNING!!!
**** THIS IS IN NO SENSE A VIABLE ENCRYPTOR!!
**** Anyone with any cryptographic skill at all should be able to break
**** this encryption algorithm with relative ease, so you should not use
**** this as a production encryptor - it is provided ONLY as an
**** illustration of how one might write to the interface.
