Project description:
"I want a compact Python script that can take a text string supplied on the command line, encrypt it with AES-256, and hide the resulting ciphertext inside a JPEG’s metadata. When run in “reveal” mode, the same script should extract the data and decrypt it back to the original message.

Key points
• Encryption must be AES-256 (CBC, GCM or another secure mode is fine).
• Only the following libraries are allowed: cryptography, rsa, pycryptodome or pycryptodomex—nothing else.
• The metadata channel is flexible. If EXIF, XMP or IPTC is convenient, feel free to pick one; I have no preference as long as it works across common image viewers.
• All interaction happens through the console:
python [login to view URL] hide [login to view URL] [login to view URL]
python [login to view URL] reveal [login to view URL]

Deliverables
1. [login to view URL] with clear, commented code. (highly detailed comments and code rationale explanation
2. A short README showing install steps and sample commands.
3. One sample JPEG demonstrating successful hide → reveal round-trip.

I will test by compiling a fresh virtual environment, running the commands above, and checking that the original text survives the full cycle unchanged." (client-provided description)
