Crate universal_hash

Traits for Universal Hash Functions.

Universal hash functions select from a "universal family" of possible hash functions selected by a key. They are well suited to the purpose of "one time authenticators" for a sequence of bytestring inputs, as their construction has a number of desirable properties such as pairwise independence as well as amenability to efficient implementations, particularly when implemented using SIMD instructions.

When combined with a cipher, such as in Galois/Counter Mode or the Salsa20 family AEAD constructions, they can provide the core functionality for a Message Authentication Code (MAC).

Structs

Error	Error type for when the Output of a UniversalHash is not equal to the expected value.
Output	Outputs of universal hash functions which are a thin wrapper around a byte array. Provides a safe Eq implementation that runs in constant time, which is useful for implementing Message Authentication Codes (MACs) based on universal hashing.

Traits

UniversalHash

The UniversalHash trait defines a generic interface for universal hash functions.
