Use SHA-3 & Extended Hash Generator

Compute SHA-3, SHAKE, SHA-224, SHA-512 variants and CRC-16/ARC from text or bytes. Start with the sample, select the options and run the tool. Copy or download the result after reviewing it.

Behavior and limits

Input is UTF-8 text, hex bytes or Base64; output is lowercase hex. SHAKE supports an explicit output length. CRC-16/ARC is a checksum, not a cryptographic hash. Plain digests are not password hashing and this tool does not compute HMAC.

Example input

abc
