Hash Generator
Generate SHA-256, SHA-384, and SHA-512 hashes from any text using the Web Crypto API.
How to use
Enter your text, select the hash algorithm, and click "Run Tool". The hash is computed entirely in your browser - no data leaves your device.
Example input
Hello, World!
Example output (SHA-256)

FAQ
What's the difference between SHA-256, SHA-384, and SHA-512?
They produce different length hashes: SHA-256 outputs 64 hex characters, SHA-384 outputs 96, and SHA-512 outputs 128. Longer hashes provide more security but are less common.
Is my data secure?
Yes! All hashing is done locally in your browser using the Web Crypto API. No data is sent to any server.
Can I reverse a hash?
No, cryptographic hashes are one-way functions by design. You cannot recover the original text from a hash.
