Thanks for all of the replies on this topic.. Still not too sure what is the best way of going really.
The reason for encryption is that the files contain personal data which we don't want to pass clear text. In an ideal world the files will unencrypt themselves as the people we are sending the files are idiots ;) so we have to make it as simple as possible for them! The caveat for this is that they us windows so it would need to be an m$ executable file that is created. We already have a tool that can do what I want, but it needs M$ to do the encryption as well, I guess I could experiment using this under dosemu / wine. As the enryption process is done via a script can dosemu be run scripted rather than interactively (ie the program I have prompts for a password, can I feen the password in via the (dosemu) calling script instead?)

Good one. Using uuencode/uudecode the problem is solved even for binaries. The only part missing is the encryption. -- __ / \\ @ __ __ @ Adolfo Bello <[EMAIL PROTECTED]> / // // /\ / \\ // \ // Bello Ingenieria S.A, ICQ: 65910258 / \\ // / \\ / // // / // celular: +58 416 609-6213 /___// // / <_/ \__\\ //__/ // fax : +58 212 952-6797 www.bisapi.com // pager : [EMAIL PROTECTED]
