Hi
I have a requirement where the keys for the crypto cipher algorithms are
already programmed in the h/w pipes/channels and thus the ->encrypt()
and ->decrypt() can be called without set_key being called first.
I see that CRYPTO_ALG_OPTIONAL_KEY has been added to take care of
such requirements for CRC-32. My question is can the usage of this flag
be extended for cipher and other crypto algorithms as well. Can setting
of this flag indicate that the algorithm can be used without calling
set_key first and then the individual drivers can handle cases where
both h/w keys and s/w keys need to be supported.
