Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-512 hashes for text and files

About this tool

The Hash Generator produces MD5, SHA-1, SHA-256, and SHA-512 fingerprints for text or files. Hashes are widely used to verify downloads, compare file contents, and generate deterministic identifiers. All hashing happens in your browser.

How to use

  1. Choose whether to hash text input or a dropped file.
  2. Pick the hash algorithm from the selector.
  3. Paste text or drop the file in the input area.
  4. Copy the resulting hash with one click.
  5. Compare two hashes by pasting the expected value into the verification field.

Common use cases

  • Verifying that a downloaded installer matches its published SHA-256.
  • Producing a deterministic key from a string for caching.
  • Checking that two files are identical without opening them.
  • Validating the integrity of a backup archive.
  • Generating a fingerprint of a password hint for comparison.

Frequently asked questions

Should I hash passwords with this tool?

No. Raw MD5 or SHA-256 should never store passwords. Use a password-hashing function like Argon2 or bcrypt on a server instead.

Is MD5 still safe?

MD5 is broken for cryptographic use but still fine for non-security checks like file fingerprints.

Does the tool upload my file?

No. Files are read with the browser File API and hashed in place. Nothing is sent to a server.

Why does the same text sometimes produce different hashes across tools?

Hashes are extremely sensitive to whitespace and encoding. Even a trailing newline will change the result.
