🔐 Hash Generator

What is Hash Generator?

The Hash Generator creates SHA-1, SHA-256, SHA-384 and SHA-512 digests for any text you type or any file you pick, all inside your browser with the Web Crypto API. Choose the algorithm and the hex output case, paste a paragraph, and the matching hash appears instantly with a one-click copy. Nothing you hash is ever uploaded — the calculation is fully local and private.

How to Use Hash Generator

1. Type or paste the text you want to hash, or click Random sample
2. Pick an algorithm and choose lowercase or uppercase output
3. Copy the digest with one click, or load a file to hash its contents instead

Why Use Our Hash Generator?

• SHA-1, SHA-256, SHA-384 and SHA-512 support with lowercase or uppercase hex output
• Optional file input so you can hash the exact contents of any local file
• Random sample button and automatic recompute on every keystroke
• 100 percent local hashing with the Web Crypto API — no uploads, no account

Common Use Cases

• Checking a checksum against one you were given for a downloaded file
• Creating a SHA-256 fingerprint of a small local document
• Quickly experimenting with how SHA-1, SHA-256 and SHA-512 outputs differ for the same text

Frequently Asked Questions

• Is hashing my text private?▾
  Yes. Hashing uses the Web Crypto API inside your browser, so your text or file never leaves your device — nothing is uploaded to any server.
• What is the difference between SHA-256 and SHA-1?▾
  SHA-256 returns a 256-bit digest shown as 64 hex characters and is cryptographically far stronger than SHA-1, which returns 160 bits (40 hex characters) and is no longer considered secure for protecting secrets.
• Can I hash an uploaded file?▾
  Yes. Use the optional file input to pick any local file and the tool reads its bytes in the browser and shows the digest for the algorithm you chose.
