Any proper encryption program is capable of encrypting ANY stream of bytes, and recovering the original. Postscript is a page layout language -- it too could be encrypted... Heck, as a Turing complete programming language (for which typesetting is just its prime focus) the decryption algorithm could even be embedded into the Postscript file -- just needing the recipient to provide it with the proper key. No Ada involved... As for LaTeX -- anyone with a copy of PGP (or its spawn: GPG) can already do what you describe... A "new" program written in Ada isn't needed. If you really want Ada involved -- rather than keep pushing your mysterious, unvetted, algorithm -- why not rewrite GPG using Ada. The result will have to be able to process anything GPG can; which means it can encrypt in forms that GPG can decrypt, and vice versa. When you can demonstrate a viable GPG fork written in Ada, 100% compatible with GPG, then you have a basis to start adding new algorithms and persuading folks to check it out. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
