Enum ProtectionProfile 

#[repr(u8)]
pub enum ProtectionProfile {
    Aes128CmHmacSha1_80 = 1,
    Aes128CmHmacSha1_32 = 2,
    Aes256CmHmacSha1_80 = 3,

}

ProtectionProfile specifies Cipher and AuthTag details, similar to TLS cipher suite

Variants

Aes128CmHmacSha1_80 = 1

SRTP_AES128_CM_HMAC_SHA1_80: AES-128 counter mode with an 80-bit HMAC-SHA1 tag.

The profile every WebRTC implementation supports.

Aes128CmHmacSha1_32 = 2

SRTP_AES128_CM_HMAC_SHA1_32: as above with a truncated 32-bit tag, trading authentication strength for 6 bytes per packet.

Aes256CmHmacSha1_80 = 3

SRTP_AES256_CM_HMAC_SHA1_80: AES-256 counter mode with an 80-bit HMAC-SHA1 tag.

Aes256CmHmacSha1_32 = 4

SRTP_AES256_CM_HMAC_SHA1_32: AES-256 counter mode with a 32-bit HMAC-SHA1 tag.

AeadAes128Gcm = 7

SRTP_AEAD_AES_128_GCM: AES-128 in GCM, which authenticates as part of encryption rather than with a separate HMAC.

AeadAes256Gcm = 8

SRTP_AEAD_AES_256_GCM: AES-256 in GCM.

Implementations

impl ProtectionProfile

pub fn key_len(&self) -> usize

The master key length in bytes for this profile.

pub fn salt_len(&self) -> usize

The master salt length in bytes for this profile.

pub fn rtp_auth_tag_len(&self) -> usize

The authentication tag length appended to each SRTP packet, in bytes.

pub fn rtcp_auth_tag_len(&self) -> usize

The authentication tag length appended to each SRTCP packet, in bytes.

pub fn aead_auth_tag_len(&self) -> usize

The AEAD tag length in bytes, for the GCM profiles; 0 for the HMAC-SHA1 ones.

pub fn auth_key_len(&self) -> usize

The HMAC authentication key length in bytes; 0 for the AEAD profiles, which derive authentication from the cipher itself.
