The flag is encoded and stored in the binary file chall.bin. Your task is to figure out how the flag was encoded and extract the original flag from the file.
Files:
- chall.py: The source code of generating the
chall.binfile. - chall.bin: The binary file containing the encoded flag.
You have a binary file, but how do you know that the ASCII codes are exactly what they should be? Maybe there is an offset!
