Hi,
I am trying to write an ABLKCIPHER algorithm for my hardware crypto
engine and I have a few questions:
1) In struct ablkcipher_alg, what do these fields do? I see some
implementations use them and some not. Do I need to implement them?
int (*givencrypt)(struct skcipher_givcrypt_request *req);
int (*givdecrypt)(struct skcipher_givcrypt_request *req);
const char *geniv;
2) What is a CRYPTO_ALG_TYPE_GIVCIPHER? What does it do and how does it
interface to other algorithms?
In case, it is important; we are using linux-2.6.28 but we will soon
move to linux-2.6.31. The ultimate goal is to accelerate
authenc(cbc(aes),hmac(sha1)) and I am currently implementing the simpler
algorithms as a learning exercise.
Regards,
Dimitris
