Can you use PGP after you buy ViaCrypt? After all, you paid for ViaCrypt, and since it's supposedly the same as PGP, can you simply use PGP and mention that you have purchased ViaCrypt? The other thing you could do is get a PC hooked up via appletalk to your Mac network (or via ethernet, etc.) You could send batch files for it to execute somehow, and it should run in full speed. Something like all the Macs on the network have a shared directory with the PC which runs PGP... On the PC end, there's a program that looks in this directory, reads a batch file, executes it, deletes the batch file. You'll also need some sort of file locking method. The simplest of these is to just rename the file... say, write a file called LOCKED XXXX940318132811 which the PC should ignore because it won't look like the file it wants... then when the file is closed, it can be renamed XXXYYYY.PGP which the server on the PC end will simply shell out to and then delete... the XXX in the file name could be the Mac station ID... The output of these batch files could go to a file called XXXYYY.RES for result. The batch file can include the message to sign, look at, etc... How? You can use the echo command to redirect to a file, or you can put input/output files in other directories... Shouldn't take more than a few days worth of work to implement...
