SHA-3 Text Hash Generator

Switch between SHA3-224, SHA3-256, SHA3-384, and SHA3-512 to mirror your checksum workflows. All hashing runs in-browser, and nothing touches a server. Need file hashing instead? →

Text SHA-3 Hash

Compute SHA3-224, SHA3-256, SHA3-384, or SHA3-512 digests for any text. Everything runs locally so your secrets never leave this browser tab.

Variant

Output: 256-bit digest with 64 lowercase hexadecimal characters. Switch variants anytime to compare lengths.

Input text

Current length: 0 characters

Text SHA3-256 hash

Enter text above to generate a SHA3-256 digest.

Hash validation

Enter a target hash to validate.

Hash overview

SHA-3 is the Keccak-based successor to SHA-2. It offers sponge-based permutations and supports multiple digest lengths so you can align with legacy 224/256-bit workflows or jump to 384/512-bit integrity guarantees.

All hashing stays on-device—refreshing the page clears the buffer and clipboard helpers.
