Module crypto 

End-to-end encryption using XChaCha20-Poly1305

This module provides symmetric encryption for tunnel traffic. The encryption key is generated locally and shared via URL fragment, ensuring the relay server cannot decrypt the traffic.

Structs

TunnelCrypto

Provides encryption and decryption using XChaCha20-Poly1305

Wrapper for the 256-bit encryption key

Constants

KEY_SIZE

Size of the encryption key in bytes (256 bits)

NONCE_SIZE

Size of the nonce in bytes (192 bits for XChaCha20)
