Struct ObfuscatedCipher 

pub struct ObfuscatedCipher { /* private fields */ }

AES-256-CTR stream cipher pair for MTProto obfuscated transport.

Implementations

impl ObfuscatedCipher

pub fn new(init: &[u8; 64]) -> ObfuscatedCipher

Build cipher state from the 64-byte random init buffer.

pub fn from_keys( tx_key: &[u8; 32], tx_iv: &[u8; 16], rx_key: &[u8; 32], rx_iv: &[u8; 16], ) -> ObfuscatedCipher

Build cipher from explicit key/IV pairs (used when MTProxy secret mixing has already been applied externally via SHA-256).

pub fn encrypt(&mut self, buf: &mut [u8])

Encrypt outgoing bytes in-place (TX direction).

pub fn decrypt(&mut self, buf: &mut [u8])

Decrypt incoming bytes in-place (RX direction).
