56 HMAC is a MAC (message authentication code), i.e. a keyed hash
60 HMAC() computes the message authentication code of the I<data_len> bytes at
71 HMAC does not support variable output length digests such as EVP_shake128() and
74 HMAC() uses the default B<OSSL_LIB_CTX>.
128 HMAC() returns a pointer to the message authentication code or NULL if
