Hash Generator
Generate SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text — instantly and privately in your browser.
Algorithm
Note: MD5 is intentionally not offered — it's cryptographically broken. SHA-256 or higher is recommended for security purposes.
🔒 Hashed on your device — never sent anywhere
How to generate a hash
- Pick an algorithm. SHA-256 is a great default.
- Type or paste text. The hash updates instantly.
- Copy the hash. One click copies the full digest.
Frequently asked questions
Is my text uploaded?
No. Hashing happens in your browser using the Web Crypto API — your text never leaves your device.
Which algorithm should I use?
SHA-256 is a solid default. Use SHA-384 or SHA-512 for extra strength. SHA-1 is included for legacy checks but isn't recommended for security.
Why isn't MD5 available?
MD5 is cryptographically broken and unsafe for security use, so it's intentionally left out. Use SHA-256 or higher instead.
What is a hash used for?
A hash is a fixed-length fingerprint of your data — useful for verifying file integrity, storing password digests and checksums.
