Overview/Background: We currently encrypt a file on a Linux Webserver using Blowfish encryption. We encrypt the file with a passphrase, so no need for public/private key implementation. This file is then attached to an email and sent to one of our users using Win95/98/NT/2000/XP. The user will receive the encrypted file as an attachment to an email, and must be able to click on the file, and the decryption must load (achived via file associations) When loaded it must prompt the user for his passphrase, and if correct, decrypt the file. On successful decryption as the user if he would like to view the file, or if it must be saved to disk (similar to what Outlook does when you click on an attachment) Decryption: The decryption will be done via a freeware utility called burp ([url removed, login to view]). The GUI must execute the [url removed, login to view] file with the correct parameters. Alternatively - if you can find a freeware library for Blowfish for your programming language the decryption routines can be done by the program, eliminating the need to execute an external program
