Module srtp 

SRTP (Secure RTP) implementation per RFC 3711.

Provides AES-128-CM encryption with HMAC-SHA1-80 authentication for securing RTP and RTCP media streams using SDES key exchange (RFC 4568).

Example

use rtp_engine::srtp::SrtpContext;

// Generate keying material
let (mut sender, key_material) = SrtpContext::generate().unwrap();
let mut receiver = SrtpContext::from_base64(&key_material).unwrap();

// Encrypt RTP packet
let rtp = vec![0x80, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0xA0,
               0x12, 0x34, 0x56, 0x78, 0xDE, 0xAD, 0xBE, 0xEF];
let srtp = sender.protect_rtp(&rtp).unwrap();

// Decrypt on receiver side
let decrypted = receiver.unprotect_rtp(&srtp).unwrap();
assert_eq!(decrypted, rtp);
