 // How will libsrtp select this module?
 // Libsrtp defines authentication function types identified by an unsigned
 // integer, e.g. SRTP_HMAC_SHA1 is 3. Using authentication ids, the
 // application can plug any desired authentication modules into libsrtp.
 // libsrtp also provides a mechanism to select different auth functions for
 // individual streams. This can be done by setting the right value in
 // the auth_type of srtp_policy_t. The application must first register auth
 // functions and the corresponding authentication id using
 // crypto_kernel_replace_auth_type function.
