Hash Generator
Generate SHA-1, SHA-256, SHA-384 and SHA-512 hashes.
Hashes are computed locally with the Web Crypto API — nothing is sent anywhere.
————About the Hash Generator
Generate cryptographic hashes free — SHA-1, SHA-256, SHA-384, and SHA-512 — from any text, all at once, as you type. Hashes are computed locally with the browser's Web Crypto API, so your input never touches a server: safe for checksums, cache keys, deduplication, and verifying file or string integrity. Copy any digest with one click.
How to use the Hash Generator
- 1Type or paste your text.
- 2All hashes compute instantly.
- 3Copy the hash you need.
Frequently asked questions
Are hashes computed locally?
Yes — they use the browser's Web Crypto API, so your text never leaves your device.
Why no MD5?
MD5 is cryptographically broken and not provided by the Web Crypto API. Use SHA-256 or stronger.
Can a hash be reversed to get the original text?
No — hashing is one-way. But identical inputs always produce identical hashes, which is why passwords need salting, not just hashing.
