1. A method of decrypting a file on a computer, said method including:
- receiving an electronic zip file archive at an application on a computer,wherein said electronic zip file archive includes an asymmetrically encrypted electronic file,wherein said asymmetrically encrypted electronic file was asymmetrically encrypted using an asymmetric encryption key individually selected for said electronic file by a user using said application from a plurality of available asymmetric encryption keys that are selectable using said application,wherein said electronic .zip file archive has been enhanced to include encryption information relating to said asymmetrically encrypted electronic file, but distinct from said aysmmetrically encrypted electronic file, placed inside a central directory of said electronic .zip file;
retrieving said encryption information from said .zip file archive;
retrieving said asymmetrically encrypted electronic file from said .zip file archive; and
decrypting said asymmetrically encrypted electronic file using said encryption information.
