Abstract
A method and system is provided for communicating encrypted user passwords from a client to a server. During new environment negotiations, the server communicates to the client a server random seed value. The client then generates a client random seed value and, using the client random seed value, the server random seed value, and the user variable name, an encrypted user password. The client then communicates to the server the client random seed, the user variable name and the encrypted user password. Then the server validates the encrypted user password using the server random seed, the client random seed and the user variable name.
