Abstract: A method, programmed medium and system are provided for enabling a user to choose a user-preferred encryption type from among a plurality of encryption types listed in a user's Kerberos configuration file. During the ticket granting process in a Kerberos system, a user is requested to select a preferred encryption type to be used in the Kerberos communication from among encryption types contained in the user's Kerberos configuration file. The user-selected encryption type is then implemented for use in encrypting a session ticket (as well as generating the session key of user requested encryption type) for use by the user machine in communicating securely with an Kerberized application server when being communicated by that particular user. Thus, the system allows different users to simultaneously communicate with the same Kerberized application server using a supported encryption type of the user's own choice.
