We currently take files (via FTP) off of a mainframe and save them as a text file on our server. This is done via a script. The next thing that is done to that text file is it gets zipped (using ZIP). This all works fine, but it doesn't appear that ZIP (the free version) has any way to password protect or encrypt the file. Does anyone know of a package or anything that will allow me to either encrypt or password protect the file through my Unix script? I'm sure my company won't want to pay for a product, so if there's any free ones out there, please let me know (and where to find them). Thanks, in advance, for any help you can provide.
