Add MAC API, with HMAC algorithms. Internally uses HMAC functionality of the
MD module.
[v2]:
- Add documentation for MAC API.
- Change length argument for gcry_mac_read from size_t to size_t* for
returning number of written bytes.
[v3]:
- HMAC algorithm ids start from 101.
- Fix coding style for new files.
