[Description] stegofox is a command-line tool for hiding arbitrary files inside PNG images using least-significant-bit (LSB) steganography. Payloads can optionally be encrypted with AES-256-GCM (key derived via PBKDF2-HMAC-SHA256, 100k iterations) before embedding, so a wrong password fails cleanly via the GCM auth tag rather than producing garbage output. A 4-byte magic signature plus a length header precede the embedded payload so extraction knows exactly how many bytes to read back. Output is always written as PNG to guarantee lossless round-tripping of the embedded bits. The tool also checks embedding capacity against the cover image before writing anything, so oversized payloads fail with a clear error instead of corrupting the image.

[Dependencies] Python >= 3.8, pillow, numpy, pycryptodome

[Similar tools] steghide, stegseek, zsteg, outguess, stegcracker

[Activity] Actively developed; initial release 2026, MIT licensed, test suite included (unit + integration tests covering crypto round-trip, wrong-password/tampered-ciphertext rejection, and embed/extract edge cases).
