What is Shake-256?

SHAKE256 is an Extendable-Output Function (XOF) from the SHA-3 family, based on the Keccak algorithm. It offers a higher security strength (256 bits) compared to SHAKE128. As an XOF, it can produce an output of any desired length, making it highly versatile for various cryptographic applications including domain separation and stream encryption.

Maximum Security

Provides 256-bit security strength, making it resistant even to future quantum computing threats.

Versatile XOF

Can be used as a hash function, a message authentication code, or a stream cipher component.

NIST Standard

Fully compliant with the FIPS 202 standard for SHA-3 extendable-output functions.
