1. A secure cryptographic system, comprising:

  • a depository system, remote from a user, having at least one server which stores at least one private key and a plurality of enrollment authentication data, wherein each enrollment authentication data identifies one of multiple users;

    an authentication engine, remote from said user, which compares authentication data received by from one of said multiple users to enrollment authentication data corresponding to said one of multiple users using at least one private key received from the depository system;

    a cryptographic engine which, when the authentication result indicates proper identification of the one of the multiple users, performs cryptographic functions on behalf of the one of the multiple users using the associated one or more different keys received from the depository system; and

    a transaction engine connected to route data from the multiple users to the depository server system, said authentication engine, and said cryptographic engine;

    wherein said secure cryptographic system is remote from said user and said user is connected to the system via a communication link,wherein said depository system further comprises a plurality of data storage facilities, each data storage facility having at least one server storing substantially randomized portion of said private key and a substantially randomized portion of said plurality of enrollment authentication data, andwherein each substantially randomized portion is individually undecipherable.
