Increase hash function block size to accommodate SHA3 HMAC and SHAKE-128 #21
Description
Hello,
In cf_hmac_init() key k and block blk is allocated with CF_CHASH_MAXBLK (144 bytes). However, for SHA3HMAC and SHAKE-128 use block size up to 168 bytes.
With change of macro CF_CHASH_MAXBLK to 168, we can HMAC for these algorithms.
