Hash Generator

All tools

Paste text, choose an algorithm, and get the hash instantly. Everything runs locally in your browser.

What is a hash?

A hash is a fixed-length fingerprint of input data. Even a tiny change in input produces a very different output.

Hashes are useful for checksums, integrity checks, caching keys, and quick comparisons. This tool generates hashes locally in your browser.

How to use the Hash Generator

  1. Paste text into the Input field.
  2. Choose MD5, SHA-1, or SHA-256.
  3. Click Generate (or just type — it can update automatically).
  4. Copy the result if needed.

Tips

  • Hashes are one-way; you can’t “decode” them back to the original text.
  • MD5 and SHA-1 are not recommended for security-sensitive uses.
  • For passwords, use dedicated password hashing (bcrypt/argon2), not plain hashes.

Hash Generator FAQ

Is hashing the same as encryption?
No. Hashing is one-way; encryption is reversible with a key.
Why do different tools show different results?
Usually due to different text encodings, hidden whitespace, or line endings.
Is my input sent to the server?
No. Everything runs locally in your browser.
