Frequently asked questions
What is an MD5 hash used for?
MD5 generates a fixed-length fingerprint of any input text - commonly used to verify a file or string hasn't been altered (checksums), or historically for storing password hashes (no longer recommended for that use).
Can I reverse an MD5 hash back to the original text?
No - MD5 is a one-way function by design. You can't decode a hash back to its original input, though short/common inputs can sometimes be found via precomputed lookup tables ("rainbow tables").
Is MD5 still secure for passwords?
No - MD5 is considered cryptographically broken for security-sensitive use like password storage. Modern applications should use bcrypt, scrypt, or Argon2 instead; MD5 is fine for simple checksums and non-security use cases.
