SHA-3
Secure Hash Algorithm 3 based on Keccak
SHA-3 (FIPS 202) is the NIST standard built on the Keccak sponge construction, available here in 224, 256, 384 and 512-bit sizes for both text and files. It is a good choice when you want a modern hash whose design is independent of SHA-2. SHA-3 and the original Keccak use different padding, so their outputs differ.
