md5(key)=395D0133C4EA85823B35B0886B1CE0DB<br>the key string is 0x16 long,then used to decrypt the code from the address 401000.We need the code to get the solution.<br>But I can't cracked the md5 value.
TBH I didnt even try this chall but knowing Phas I can assure you it's not a bruteforcer/guessing challenge. Probably you missed something else around.
As the challenge description already states, 309485009821345068724781056 possibilities are too many.<br>So simple BF is not the intended way to solve this.
