🟨Hash of the Server IP Address
A one-way hash is a cryptographic function that takes an input (or 'message') and returns a fixed-size string of bytes. The output is unique to each unique input, making it impossible to generate the original input from the hash. This property is crucial for applications like password storage, where the hash provides security by ensuring that passwords cannot be easily reversed.
This challenge simple asks you to figure out two things: 1) what is the IP address of the server for ctf.bizity.biz and 2) what is the hash of that ip address.
There are multiple hash algorithms out there and this one asks for the MD5.
MD5, while historically popular, is considered cryptographically broken and unsuitable for further use. Its weaknesses include susceptibility to hash collisions, where two different inputs produce the same hash output. This vulnerability undermines its integrity, making it insecure for digital signatures and certificates. Additionally, MD5 is vulnerable to extensive brute force and dictionary attacks due to advances in computational power. It's recommended to use more secure hashing algorithms like SHA-256 for cryptographic purposes.
