Frequently Asked Questions
What is a hash function?
A function that turns any input into a fixed, unique string; it is one-way and used for data integrity and secure password storage.
What is the difference between MD5 and SHA-256?
MD5 is old and broken for security; it is only suitable for quick checksums. SHA-256 is secure and the modern standard for security uses.
Can a hash be reversed?
A hash is one-way by design and not directly reversible; but simple inputs can be guessed with precomputed tables, so passwords use a "salt".
