crypto: engine - replace pr_xxx by dev_xxx

2017-06-19T06:19:54+00:00

By adding a struct device *dev to struct engine, we could store the
device used at register time and so use all dev_xxx functions instead of
pr_xxx.

crypto: akcipher - assume key is already set in maxsize

2017-06-10T04:04:29+00:00

As of now, crypto_akcipher_maxsize() can not be reached without
successfully setting the key for the transformation. akcipher
algorithm implementations check if the key was set and then return
the output buffer size required for the given key.

Change the return type to unsigned int and always assume that this
function is called after a successful setkey of the transformation.
akcipher algorithm implementations will remove the check if key is not NULL
and directly return the max size.

crypto: hmac - add hmac IPAD/OPAD constant

2017-05-23T04:52:05+00:00

Many HMAC users directly use directly 0x36/0x5c values.
It's better with crypto to use a name instead of directly some crypto
constant.

This patch simply add HMAC_IPAD_VALUE/HMAC_OPAD_VALUE defines in a new
include file "crypto/hmac.h" and use them in crypto/hmac.c
