What is a Rainbow Table? 🌈

A rainbow table might sound colorful, but it’s a serious tool in the world of cybersecurity. Essentially, it’s a database that links common inputs (like passwords) to their hashed outputs. For example, passwords like “12345678” or “qwerty” can be easily matched to their SHA256 hash values using a rainbow table. While hashing should keep passwords secure, these precomputed tables make it easy for hackers to reverse-engineer and discover the original passwords from their hashes.

This is why protecting passwords with a salt is so critical! A salt adds a unique random value to each password before hashing, making rainbow tables ineffective. Unfortunately, when companies lose poorly secured password databases, hackers can exploit these tools to gain access. The takeaway? Always use strong, unique passwords and trust platforms with modern security practices to safeguard your data.
