Options:
--version show program's version number and exit
-h, --help show this help message and exit
-D ID, --device=ID connect to device with the given ID
-U, --usb connect to USB device
-R, --remote connect to remote frida-server
-H HOST, --host=HOST connect to remote frida-server on HOST
-O FILE, --options-file=FILE
text file containing additional command line options
-m MODE, --mode=MODE choose "e" for encrypt, or "d" for decrypt, or "l" for
hot load into device
-p PKG, --pkg=PKG package name or process name in android device to be
attached
--id=INPUT_DIR directory of input files. entry js file(e.g main.js)
will not be recognized if project.json not in this
directory
--od=OUTPUT_DIR directory of output files
--if=INPUT_FILE directory of single input file
--of=OUTPUT_FILE directory of single output file
--isui whether the file to be encrypted specified by -if is
an ui script
- 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
