Abstract

A system for encrypting computer files associates a key file with the encrypted file. Operations performed on the encrypted file are also performed on the key file. The key file includes a list of users to whom the encrypted file is available together with the public key certificates for those users. The symmetric key is held in the key file wrapped with the authorised user certificates.
