Notes and Comments
- ARM files are encrypted with custom algorithm. Special 256-bytes key is needed for decryption. Key starts with string "mr8".
Decryption algorithm
Below is Python implementation of decryption algorithm:
arm_size = os.path.getsize(in_file_path)
for i in range(arm_size):
arm_byte = struct.unpack("B", arm_file.read(1))[0]
key_file.seek(arm_byte)
out_byte = key_file.read(1)
out_file.write(out_byte)
