Struct Kmac

Source
pub struct Kmac { /* private fields */ }
Expand description

The KMAC pseudo-random functions defined in SP800-185.

The KECCAK Message Authentication Code (KMAC) algorithm is a PRF and keyed hash function based on KECCAK. It provides variable-length output, and unlike SHAKE and cSHAKE, altering the requested output length generates a new, unrelated output. KMAC has two variants, KMAC128 and KMAC256, built from cSHAKE128 and cSHAKE256, respectively. The two variants differ somewhat in their technical security properties.

§Usage

[dependencies]
tiny-keccak = { version = "2.0.0", features = ["kmac"] }
