# IPromise
- Run the decryptIPromise() => got the flag in ecrypted.
# Taylor Swift
- We have key, enc, and xor encrypt => A ^ B = C => A = B ^ C

from base64 import b64decode as d
from pwn import xor
enc = "FRsIAQ8PVBUVEREIVERbBkURFkUIBxVQVkAYFxJfV0FYVkIVQgo="
key = "swifties!"

print(xor(d(enc), key.encode()))

# What's in the box
- You recognize the script was generated using Makeself.
- Makeself is a self-extracting archive file, meaning that you have to create a folder to contain all extracted file from it.
- Open file test:
- Open file python, you will see.
- Overwrite in vsc, then get the flag.
# A Locked Box
- We got a shell script for this challenge generated by Makeself again.
- We see the expected error, not correct hash, but we have the correct value of the hash so let’s change it.
- we see the 2 corrupted bytes, lets fix them with the correct hex values
`0x66 for “f” | 0x37 for “7”`
- I have changed it on visual code but got corrupted, so i fixed them on HxD.
- This is your flag:
