Examples

• decrypt a file

# decrypt ./assets/project/main.js to ./src/main.js
./unpacker.py -U -m d -p com.example.pkg --if ./assets/project/main.js --of ./src/main.js

• encrypt a file

# encrypt ./src/main.js to ./src_en/main.js
./unpacker.py -U -m e -p com.example.pkg --if ./src/main.js --of ./src_en/main.js

• hotload a file

# encrypt and load ./src/main.js to (data)/main.js
# this will encrypt ./src/main.js on your computer and replace with app's cache on your phone, so that you can quickly see the effect of modifying the script.
./unpacker.py -U -m l -p com.example.pkg --if ./src/main.js --of main.js
