This challenge combines forensics, crypto and programming. A 4096 bit RSA key is used to encrypt the flag and both the encrypted key and the encrypted flag are hidden inside the jpeg. Python scripts are also provided to help decrypt the RSA key which is xor'd with bytes from the jpeg. These same Python scripts can be used as part of solving my 100 point Scope challenge. Good Luck! You may want to solve my MountainMan challenge first if you are having difficulty finding the key and flag hidden in the jpeg.
