Initialize a HMAC CTX with hashing algorithm 'name'
This feature relies on having external libraries enabled:
With ENABLE_OPENSSL: Adds the full range of OpenSSL supported hash algorithms
With ENABLE_GNUTLS: Adds sha256, sha512, sha1, md5, RIPEMD-160, MD2, SHA224, SHA384
See hmacdata(), hmacfile(), hmacfile_fp(), and hmacfile_rw() for one-shot convenience functions. The hmacfile* ones automatically HMAC the file in 32K chunks so it won't try to load the entire file into memory or anything.
- Parameters
-
| name | The name of the hashing algorithm. |
| key | The secret key to use. |
| length | The length of the secret key. |
