Struct ObfCipher 

pub struct ObfCipher { /* private fields */ }

Rolling AES-CTR key state. In practice Obfuscated2 uses straight XOR with a stream derived from the initial nonce, so we model it as a key stream.

Implementations

impl ObfCipher

pub fn new(key: [u8; 32], iv: [u8; 16]) -> Self

pub fn fill(&mut self)

Extend the keystream buffer using repeated SHA-256 rounds (simplified).

pub fn apply(&mut self, data: &mut [u8])

XOR data in-place with the rolling keystream.
