Hash Generator — SHA-256, SHA-512 in your browser
Compute SHA-1, SHA-256, SHA-384 and SHA-512 hashes from text, instantly.
This tool runs entirely in your browser. Your files are never uploaded — they stay on your device.

MD5 is not offered: it is not part of the browser’s Web Crypto standard. Only platform-supported algorithms (SHA-1, SHA-256, SHA-384, SHA-512) are computed here.
Paste or type any text and this tool computes its cryptographic hash using the browser’s built-in Web Crypto API. You get SHA-1, SHA-256, SHA-384 and SHA-512 digests side by side, each ready to copy with a single click.
Nothing is ever uploaded. The text you enter never leaves your device — every digest is calculated locally, which makes this safe for tokens, secrets and other sensitive strings.
How to use Hash Generator
- Type or paste your text into the box above.
- Hashes update automatically as you type, in SHA-1, SHA-256, SHA-384 and SHA-512.
- Click the copy button next to any hash to copy it to your clipboard.
- Clear the input to start over with new text.
Frequently asked questions
Is my text uploaded to a server?
No. Hashes are computed entirely in your browser with the Web Crypto API. Your text never leaves your device, so it is safe to hash sensitive strings.
Why is MD5 not available?
MD5 is not part of the browser’s Web Crypto standard, so it cannot be computed natively without adding a third-party library. We only offer the algorithms supported directly by the platform: SHA-1, SHA-256, SHA-384 and SHA-512.
Which hash should I use?
SHA-256 is a strong, widely used default for checksums and integrity checks. SHA-384 and SHA-512 offer longer digests. SHA-1 is included for legacy compatibility but is no longer considered secure for cryptographic purposes.
What character encoding is used?
The text is encoded as UTF-8 before hashing, which matches the behaviour of most command-line and server-side hashing tools.
