How to Use

About Hash

A hash is a fixed-length string generated from any data. The same input always produces the same hash, but the original data cannot be recovered.

Features

  • 5 AlgorithmsSupports MD5, SHA-1, SHA-256, SHA-384, and SHA-512.
  • Text & File SupportCalculate hashes for both text and any file type.
  • One-click GenerationGenerate all algorithm hashes with a single button click.
  • Privacy ProtectedAll processing happens in your browser. Data is never sent to servers.

Use Cases

  • Verify downloaded file integrity
  • Hash passwords
  • Detect duplicate data
  • Detect file tampering
  • Generate cache keys

Hashes pair nicely with password management and ID generation. Try our Password Generator for strong passwords, the Password Strength Checker to test them, and the UUID Generator for unique identifiers. Learn how hashing works and how the algorithms differ in our guide to hash functions.

FAQ

Is the hash generator free?
Yes, it is completely free. No registration required.
What is the difference between MD5 and SHA-256?
MD5 generates 128-bit hashes, SHA-256 generates 256-bit. SHA-256 is more secure.
Can I recover the original data from a hash?
No, hashes are one-way functions. The original data cannot be recovered.
Are my files safe?
All processing happens locally in your browser.
Can it handle large files?
Yes, within browser memory limits.
Can I generate multiple algorithms at once?
Yes. Enter text or a file and click Generate to calculate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes all at once. Copy each hash individually with its row button, or use "Copy All" to grab them together.
Can I display hashes in uppercase?
Yes. Turn on the "Uppercase" checkbox to show all hash values in uppercase (A–F). Toggling the format updates instantly without regenerating.
