+  cryptography - USER GUIDE (Android Python STB) - Generated by RIMI
+================================================================================
+
+  Package:     cryptography
+  Description: Cryptographic primitives and recipes for Python (static OpenSSL).
+  Extension:   cryptography.pyd
+  Language:    C+CFFI
+  Dependencies: cffi
+
+================================================================================
+  1. OVERVIEW
+================================================================================
+
+cryptography is the most popular Python library for cryptography. It
+provides cryptographic recipes and primitives to developers. This build
+uses a statically linked OpenSSL backend for maximum portability on
+Android STB devices.
+
+================================================================================
+  2. INSTALLATION
+================================================================================
+
+From Android shell or Termux:
+
+    pip install /path/to/cryptography-*.whl
+
+Or from within a build environment:
+
+    python -m pip install --no-build-isolation cryptography
+
+================================================================================
+  3. VERIFICATION
+================================================================================
+
+After installation, verify the package loads correctly:
+
+    python -c "import cryptography; print('OK')"
+
+Run the pre-built test script (if available):
+
+    python Scripts/test_cryptography.py
+
+================================================================================
+  4. USAGE EXAMPLE
+================================================================================
+
+    from cryptography.fernet import Fernet
+
+    key = Fernet.generate_key()
+    f = Fernet(key)
+    token = f.encrypt(b"Secret message")
+    decrypted = f.decrypt(token)
+
+================================================================================
+  5. TROUBLESHOOTING
+================================================================================
+
+  - If import fails with "cannot find shared library" the wheel was not
+    built with a static linking strategy. Rebuild with the correct
+    build script.
+  - cffi must be installed before using this package.
+  - Ensure OpenSSL was built with all required features enabled.
+  - Ensure your Android Python STB environment matches the ABI that
+    the wheel was compiled for (typically arm64_v8a / aarch64).
