# Magician (Web)
This web challenege had an input field where it was asking for us to input the string whose md5 hash will be equal to the given one meaning a hash collision where hashes of different file or string are similar

I tried to give some random text and in the bottom it should be the md5 hash of that string

But we need to put a string whose hash will be the same like this `0e365027561978452045683563242341` I tried to crack this md5hash using crackstation and hashcat but failed ,so I googled for this hash

So we just have to submit this string `QNKCDZO` and we will pass the condition
