    The private key is stored on the user's computer hard disk or on an external device such as a USB token. The user retains control of the private key; it can only be used with the issued password. The public key is disseminated with the encrypted information. The authentication process fails if either one of these keys in not available or do not match. This means that the encrypted data cannot be decrypted and therefore, is inaccessible to unauthorized parties.
