The HMAC hardware module allows performing NIST HMAC algorithms as standardized in the FIPS 198-1. The module is coupled with one of the NIST standard secure hash algorithm, SHA-1, SHA-256, ... The ...

HMAC supports any combination of SHA-2 algorithms, bit-length keys and messages. XTS-AES supports 128, 192 and 256-bit key sizes; whole block ciphering; and provides length-preserving encryption. The ...

* MD5-based HMAC algorithms will be disabled by default. In the just-released version 7.0, there are a number of cryptographic changes, as well.
