crypto: hmac - add hmac IPAD/OPAD constant
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 Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
