Client-Side password encryption the 800lb Gorilla is your sysadmin
Nowadays (think HostGator & Ed. Snowden), Systems Administrators cannot be trusted by default. Password security should not depend on their ability to monitor the server traffic. We solve this problem. Problem Statement: Prevent the system administrator (or a malicious root) from accessing in-transit authentication tokens (in-the-middle access). Solution: Use an external semi-dumb asymmetric key hardware token (the Sibyl), with new modifications.
