A method, computer program product, and system for selecting and generating a key to perform a cryptographic operation are described. The method includes receiving one or more inputs representing criteria for the key, the one or more inputs excluding an explicit identification of the key and one of the one or more inputs specifying the cryptographic operation; retrieving, from a memory device, information corresponding with the one or more inputs; selecting and generating the key based on the one or more inputs and the information; and performing the cryptographic operation using the key.
