A technique of providing a cryptographic service on a computer having a processor includes deploying an executable cryptographic agent set on the computer, each executable cryptographic agent from the executable cryptographic agent set being a set of instructions executed on the processor. The technique also includes activating an executable cryptographic agent on the computer, each executable cryptographic agent being constructed and arranged to generate cryptographic codes which change over time in response to activation of the agent. The technique further includes providing, to an application running on the computer, access to the executable cryptographic agent through a Personal Computer/Smart Card (PC/SC) interface of the computer.
