I started looking at this today.
I'm wondering if I'm heading in the right direction since
this is stretching my understanding of the API:
Would it look something like ccm, in that
alloc does
- crypto_grab_skcipher(spawn, "cbc(aes)"
- crypto_skcipher_spawn_alg()
then my alg.cra_init does
- crypto_spawn_skcipher ?
Any advice appreciated. In the meantime I'll read the code
to get a better understanding of how this fits together.
