[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).

Hello,

Thanks for your submission. We can’t package every infosec tool, so we prioritize those with wider adoption and community usage.

Best of luck with your project.
