Port encode/decode/tools/about routes from stegasoo (2,083 lines)
New file stego_routes.py: - register_stego_routes() mounts all encode/decode routes on the Flask app - Async encode with ThreadPoolExecutor + progress polling - Subprocess isolation for crash-safe stegasoo operations - Image + audio encode/decode with full validation - Encode result display with download - Tools API routes (capacity, EXIF, rotate, compress, convert) - About page with crypto documentation Real templates (replacing stubs): - encode.html (889 lines): full form with carrier upload, passphrase, PIN, RSA key, embed mode selection, async progress bar - decode.html (681 lines): decode form with credential inputs - encode_result.html (242 lines): result display with download - about.html (602 lines): security documentation All routes verified working with auth flow.
