Struct tox_packet::dht::CryptoHandshake

pub struct CryptoHandshake {
    pub cookie: EncryptedCookie,
    pub nonce: Nonce,
    pub payload: Vec<u8>,
}

Packet used to establish net_crypto connection between two peers.

When Alice establishes net_crypto connection with Bob she should get valid Cookie from him and send CryptoHandshake packet. Connection considered established when both Alice and Bob received CryptoHandshake packet from each other with valid cookies.

Serialized form:

Length	Content
1	0x1a
24	Nonce for the cookie
88	Cookie
24	Nonce for the payload
248	Payload

Fields

cookie: EncryptedCookie

Encrypted cookie used to check that the sender of this packet received a cookie response

nonce: Nonce

Nonce for the current encrypted payload

payload: Vec<u8>

Encrypted payload

Implementations

impl CryptoHandshake

pub fn new(
    shared_secret: &PrecomputedKey,
    payload: &CryptoHandshakePayload,
    cookie: EncryptedCookie
) -> CryptoHandshake

Create CryptoHandshake from CryptoHandshakePayload encrypting it with shared_key and from EncryptedCookie.

pub fn get_payload(
    &self,
    shared_secret: &PrecomputedKey
) -> Result<CryptoHandshakePayload, GetPayloadError>

Decrypt payload with precomputed key and try to parse it as CryptoHandshakePayload.

Returns Error in case of failure:

• fails to decrypt
• fails to parse CryptoHandshakePayload
