Module fcp_cryptoauth::handshake_packet

Contains the HandshakePacket structure, and a HandshakePacketBuilder to construct it field by field.

Example

use fcp_cryptoauth::handshake_packet::{HandshakePacketBuilder, HandshakePacket, HandshakePacketType};
let packet = HandshakePacketBuilder::new()
        .packet_type(&HandshakePacketType::Key)
        .auth_challenge(&[1u8; 12])
        .random_nonce(&[2u8; 24])
        .sender_perm_pub_key(&[3u8; 32])
        .msg_auth_code(&[4u8; 16])
        .sender_encrypted_temp_pub_key(&[5u8; 32])
        .encrypted_data(&vec![6u8, 7u8, 8u8])
        .finalize()
        .unwrap();
assert_eq!(packet.packet_type(), Ok(HandshakePacketType::Key));
assert_eq!(packet.auth_challenge(), [1u8; 12]);
assert_eq!(packet.random_nonce(), [2u8; 24]);
