$ ./sonicrack.py -h
usage: sonicrack.py [-h] [-k KEYS_DIR] [-o OUTPUT_DIR] IMAGE_PATH

A tool to decrypt SonicOSX NSv firmware. Run it against an OVA image first to extract keys, then it can also decrypt SIG images.

positional arguments:
  IMAGE_PATH            Path to encrypted firmware image (supported file extensions: .ova, .sig)

options:
  -h, --help            show this help message and exit
  -k KEYS_DIR, --keys KEYS_DIR
                        Directory path where keys are stored (defaults to ./keys)
  -o OUTPUT_DIR, --output OUTPUT_DIR
                        Directory path where decrypted firmware is saved (defaults to ./)

[-] Keys must be extracted from an OVA image before a SIG image can be decrypted
[-] If already extracted, use --keys to indicate the directory where they are saved
