ABSTRACT:
Cryptographic provider failover is performed. Upon receipt of a first security request, an integrated cryptographic provider constructs a table including a list of underlying cryptographic providers for service type algorithm pairs. The integrated cryptographic provider is one of the underlying cryptographic providers in the list. The underlying cryptographic providers are registered as hardware and software cryptographic providers in the list. The integrated cryptographic provider is registered as a routing cryptographic provider in the list. The list is arranged so that the integrated cryptographic provider has the highest priority. The integrated cryptographic provider specifies fai lover support for all registered service type algorithm pairs using one or more of the underlying cryptogaphic providers. In response to a subsequent security request, the integrated cryptographic utilizes the list of the underlying cryptographic providers to identify a second cryptographic provider to which the request will be routed if a first cryptographic provider fails.
