+ ## Implementation Notes
+ 
++  * It is possible to configure which 3rd party (ie openssl/nss/etc) crypto backend
++    libSRTP will be built with. If no 3rd party backend is set then libSRTP provides
++    an internal implementation of AES and Sha1. The internal implementation only
++    supports AES-128 & AES-256, so to use AES-192 or the AES-GCM group of ciphers a
++    3rd party crypto backend must be configured. For this and performance reasons it
++    is highly recommended to use a 3rd party crypto backend.
++  
+   * The `srtp_protect()` function assumes that the buffer holding the
+     rtp packet has enough storage allocated that the authentication
+     tag can be written to the end of that packet. If this assumption
