XXH3 class

This is an implementation of 64-bit XXH3 hash algorithm of xxHash family derived from https://github.com/Cyan4973/xxHash

XXH3 is a new high-performance variant XXHash algorithm that is designed to be fast, with a low memory footprint, and to produce high-quality hash values with good distribution and low collision rates.

One of the main improvements in XXH3 compared to XXHash is its use of a new mixing function that provides better mixing of the input data and results in improved distribution of the resulting hash values.

WARNING: It should not be used for cryptographic purposes.

Methods

bind(Stream<List<int>> stream) → Stream<HashDigest>

Transforms the byte array input stream to generate a new stream which contains a single HashDigest

inherited

byteStream(Stream<int> stream, [int bufferSize = 1024]) → Future<HashDigest>

Consumes the entire stream of byte array and generates a HashDigest.

inherited

cast<RS, RT>() → StreamTransformer<RS, RT>

Provides a StreamTransformer<RS, RT> view of this stream transformer.

inherited

convert(List<int> input) → HashDigest

Process the byte array input and returns a HashDigest.

inherited

createSink() → XXH3Sink64bit

Create a HashDigestSink for generating message-digests

override

hex(List<int> input) → String

Process the byte array input and returns a hash in hexadecimal.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pbkdf2(List<int> salt, {PBKDF2Security security = PBKDF2Security.good, int? iterations, int? keyLength}) → PBKDF2

Available on BlockHashBase<BlockHashSink>, provided by the PBKDF2onBlockHashBase extension

Generate a secret using PBKDF2 hash algorithm.

string(String input, [Encoding? encoding]) → HashDigest

Process the input string and returns a HashDigest.

inherited

stringStraem(Stream<String> stream, [Encoding? encoding]) → Future<HashDigest>

Consumes the entire stream of string and generates a HashDigest.

inherited

toString() → String

A string representation of this object.

inherited

withSecret(List<int> secret) → XXH3

Get an instance of xxh3 with a secret

withSeed(int seed) → XXH3

Get an instance of xxh3 with an specific seed

Operators

operator ==(Object other) → bool

The equality operator.
