Hash Generator

Generate SHA-1, SHA-256, SHA-512 hashes

About Hash Generator

Hash Generator computes SHA-1, SHA-256, and SHA-512 hashes of the text you type, using the browser's built-in Web Crypto API — nothing is sent to a server. All three hashes are generated together automatically; there's no algorithm picker, no MD5 (the Web Crypto API doesn't provide it), and no file upload — only pasted or typed text.

How to use Hash Generator

  1. 1Type or paste text into the input box.
  2. 2Click 'Generate Hashes' to compute all three hashes at once.
  3. 3Read the SHA-1, SHA-256, and SHA-512 results below.
  4. 4Click 'Copy' next to any hash to copy it to your clipboard.

Frequently Asked Questions

What is a hash used for?

A hash is a fixed-length fingerprint of input data, used for verifying data integrity, checksums, and (with appropriately slow, salted algorithms — not these general-purpose ones) password storage.

Which algorithms does this tool support?

SHA-1, SHA-256, and SHA-512, computed together every time. MD5 and SHA-384 aren't available, since this tool relies on the browser's Web Crypto API, which doesn't provide MD5.

Is my data uploaded to a server?

No, hashing happens entirely in your browser using the Web Crypto API.

Can I hash a file instead of typed text?

No — only text you type or paste into the box can be hashed; there's no file upload option.

Tips & Tricks

  • ✓Avoid SHA-1 for anything security-sensitive — it's included for compatibility with older systems, but SHA-256 or SHA-512 are the safer general-purpose choices.
  • ✓None of these are appropriate for hashing passwords directly — use a dedicated slow, salted algorithm (like bcrypt or Argon2) for that instead.
  • ✓To hash a file's contents, you'd need to extract the text first, since this tool only accepts typed or pasted text.
  • ✓Even a one-character difference in the input produces a completely different hash — useful for verifying exact text matches.
