What is a hash and what is it used for?

A hash is a fixed-length string generated from input data using an algorithm like MD5 or SHA-256. It's used to verify file integrity, store passwords securely, and create unique identifiers.

What is the difference between MD5 and SHA-256?

MD5 produces a 32-character hash and is fast but no longer considered cryptographically secure. SHA-256 produces a 64-character hash and is the modern standard for security applications.

Is this hash generator safe to use for passwords?

For verifying file integrity, yes. For password storage, you should use a purpose-built password hashing algorithm like bcrypt or Argon2, not MD5 or plain SHA-256.
