System and method for protecting a multipurpose data string used for both decrypting data and for authenticating a user

摘要

A method and system for protecting a multipurpose data string used for both decrypting data and for authenticating a user utilizes a remote storage element that contains a long random data string or password protected by a short easy to remember access data, such as a personal identification number or other user authentication mechanism. The remote storage element contains data used for both initially encrypting secret private keys and for later decrypting the encrypted secret private keys, or other secret data, so they can be used to decrypt data transferred within a computer network, or be used for digitally signing data transferred within a computer network.
