SHA3-512 Hash Generator

Summary

SHA3-512 is part of the SHA-3 family (NIST FIPS 202) and produces a 512-bit (128 hex character) digest. It uses the Keccak sponge construction, making it structurally different from SHA-2. This tool runs entirely in your browser via the js-sha3 library — no input is ever transmitted to a server.

How it works

1. Type or paste any text into the input field.
2. The SHA3-512 hash is computed instantly as you type.
3. Toggle between lowercase and uppercase hex output with the case button.
4. Click "Copy Hash" to copy the 128-character digest to your clipboard.
5. Use "Clear" to reset both the input and the output.

Use cases

• Verify file integrity by hashing content and comparing digests.
• Generate a deterministic fingerprint for any text or data.
• Test SHA3-512 output during cryptographic library integration.
• Produce checksums for passwords or tokens before storing.
• Compare two strings by checking whether their hashes match.
• Demonstrate the avalanche effect — changing one character flips the entire digest.
