BlowFish is a small, easy to use, file encryption utility. Simply drag and drop files and folders to quickly protect your sensitive documents, and then enter an encryption key to encode and decode the files you want to protect from prying eyes. Files can be quickly encrypted and decoded directly from the Windows Explorer by using the pop-up context menu. It uses the Blowfish encryption algorithm. Can be configured to optionally place its program icon in the taskbar notification tray.
