Package Exports

keccak-wasm

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (keccak-wasm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

keccak-wasm

This is a WebAssembly implementation of the Keccak hashing functions. This library supports keccak224, keccak256, keccak384, and keccak512

This module will return Buffers as its results should a global Buffer object exists. If one doesn't, it will return Uint8Arrays

Usage and example:

const {InitializeKeccak, Keccak, keccak224, keccak256, keccak384, keccak512} = require("keccak")
await InitializeKeccak(); // This must be called before using this library.

//keccak256(data, hexString = true);
keccak256("Hello, hello! Testing testing"); // "3cf7012953f4e04a80da00065c1f12ce47bdd24633879c29e35bb12e5f6f54a8"
keccak256("Hello, hello! Testing testing", true); // "3cf7012953f4e04a80da00065c1f12ce47bdd24633879c29e35bb12e5f6f54a8"
keccak256("Hello, hello! Testing testing", false); // "Buffer <3cf7012953f4e04a80da00065c1f12ce47bdd24633879c29e35bb12e5f6f54a8>"

// Constructor can take the values 224, 256, 384, and 512
keccak = new Keccak(256);

// keccak.update(data (Uint8Array or string), paranoia = true)
// When paranoia is true, data will be wiped from its internal memory after being processed
keccak.update("Hello, hello! Testing testing");

// keccak.final(hexString = true, destroy = true, paranoia = false)
// When destroy is true, the Keccak object cannot be reused.
// Paranoia defaults to false since the given data is wiped by default in keccak.update
keccak.final() // "3cf7012953f4e04a80da00065c1f12ce47bdd24633879c29e35bb12e5f6f54a8"
