LsbImage

shadowforge_lib::adapters::stego

Struct LsbImage

pub struct LsbImage;

Expand description

LSB image steganography adapter for PNG/BMP.

Embeds payload in the least significant bits of RGB channels only (alpha channel is untouched). Header encodes 32-bit big-endian payload length.

Implementations§

impl LsbImage

pub const fn new() -> Self

Create a new LSB image embedder.
