v0.1.0 — Initial release

v0.1.0 — Initial release

Encrypted LSB steganography CLI: hide any file inside a PNG image,
optionally protected with AES-256-GCM before embedding.

Fixed during development

• The core embed command crashed on every single call under any
  current NumPy install (NumPy 2.x rejects ~1, a Python int,
  against a uint8 array) — verified and fixed before this was ever
  usable.
• A successfully-extracted empty payload was silently reported as
  failure due to a truthiness check on bytes.

Requirements

Python >= 3.8, pillow, numpy, pycryptodome.
