Struct SrtpContext 

pub struct SrtpContext { /* private fields */ }

SRTP cryptographic context for a single media session.

Maintains session keys and rollover counter for sequence number tracking.

Implementations

impl SrtpContext

pub fn new(master_key: &[u8], master_salt: &[u8]) -> Result<Self>

Create a new SRTP context from master key and master salt.

The master key must be 16 bytes and master salt must be 14 bytes (AES_CM_128_HMAC_SHA1_80 profile).

pub fn from_base64(b64_key_material: &str) -> Result<Self>

Create from base64-encoded keying material (as used in SDP a=crypto).

pub fn generate() -> Result<(Self, String)>

Generate random keying material and return (context, base64-key).

pub fn protect_rtp(&mut self, rtp_packet: &[u8]) -> Result<Vec<u8>>

Encrypt and authenticate an RTP packet.

pub fn unprotect_rtp(&mut self, srtp_packet: &[u8]) -> Result<Vec<u8>>

Verify and decrypt an SRTP packet.

pub fn protect_rtcp(&mut self, rtcp_packet: &[u8]) -> Result<Vec<u8>>

Encrypt and authenticate an RTCP packet.

pub fn unprotect_rtcp(&mut self, srtcp_packet: &[u8]) -> Result<Vec<u8>>

Verify and decrypt an SRTCP packet.

Trait Implementations

impl Debug for SrtpContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
