Sanzan
Sanzan is a simple encryption library to encrypt and decrypt videos while maintaining playability.
It uses NumPy and OpenCV to perform video frame manipulation, while using FFmpeg and Pydub for audio manipulation. Sanzan can be used either from the command line or in a Python program.

Installation
Prerequisite
FFmpeg must be installed and in PATH.
pip install sanzan
Usage
Encryption
sz original.mp4 -k <key> -e -o encrypted.mp4
On a stream
sz https://youtu.be/dQw4w9WgXcQ -k <key> -e -o encrypted.mp4
Decryption
sz encrypted.mp4 -k <key> -d -o decrypted.mp4
With preview
sz encrypted.mp4 -k <key> -d -o decrypted.mp4 -p
- Frames will be displayed as quickly as they are generated.
- Audio will only start playing after the whole stream has been processed.
More Usage
Omit the -k argument to encrypt using randomly generated keyfiles.
Use the -m argument to specify mode: audio, video or full (default).
Use the -q flag for quiet mode.
Audio options
Use the -a argument to specify output audio format: mp3, wav (default), flac, etc.
Use the -l flag to use light encryption/decryption.
Use the -dn flag to apply denoising to the output audio.
Use the -pp flag to disable audio padding.
Video options
Use the -s argument to specify scramble method: rows (default), cols, full.
Use the -f flag to generate a different scramble order every frame.
Python Usage
Alternatively, Sanzan provides a Python interface to programmatically access its functionality.
Encryption
from sanzan import Sanzan
if __name__ == "__main__":
s = Sanzan("original.mp4")
s.set_password("1234")
s.encrypt("encrypted.mp4")
Decryption
from sanzan import Sanzan
if __name__ == "__main__":
s = Sanzan("encrypted.mp4")
s.set_password("1234")
s.decrypt("decrypted.mp4", preview=True, denoise=True)
