Struct CryptoHandshake

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

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:

LengthContent
10x1a
24Nonce for the cookie
88Cookie
24Nonce for the payload
248Payload

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§

Source§

impl CryptoHandshake

Source

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

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

Source

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
