Frequently Asked Questions
A hash is a fixed-size fingerprint of data. The same input always produces the same hash, but you cannot reverse a hash back to the original data.
MD5 produces 128-bit hashes (32 hex chars), SHA256 produces 256-bit (64 hex chars). SHA256 is more secure and recommended for modern applications.
Plain hashes (MD5/SHA) are not secure for passwords as they can be cracked via rainbow tables. Use bcrypt or Argon2 for password storage.
