Challenge Description
From the challenge description and name, we can tell that the challenge’s about cryptographic hash functions. But we don’t know which.
Understanding the challenge
After I launched an instance, I was given this command to run:
nc saturn.picoctf.net 62154After using this command to connect to the server, I realised what the challenge was all about. We are given a random text, and we are required to provide the MD5 hash of the text. After submitting 3 correct MD5 hashes of 3 different strings, we are given the flag.
For this challenge, I just used a random online MD5 hash generator to acquire the MD5 hashes. Any works!
