CryIf

AUTOSAR Crypto Interface — abstraction between CSM and the underlying crypto driver.

CryIf decouples CSM clients from the specific crypto driver in use (HSM, software). Each crypto primitive is mapped to a channel/key/algorithm triple via CryIf configuration, so changes in the driver layer don't require recompiling consumers.
