Imagine you have a file or a password, and you want to make sure it stays exactly the same, with no tampering. That’s where SHA-256 comes in. Short for Secure Hash Algorithm 256-bit, it’s a way to turn any data—text, files, or passwords—into a unique 256-bit code, often called a "hash" or "digital fingerprint." If even a single letter in your data changes, the hash will be completely different. This makes SHA-256 a powerful tool for checking data integrity.
SHA-256 is part of the SHA-2 family, designed by the National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) in 2001. It’s considered highly secure and is used in many areas, such as: -
