Package Exports

@chainsafe/as-chacha20poly1305
@chainsafe/as-chacha20poly1305/lib/src/index.js

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 (@chainsafe/as-chacha20poly1305) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

as-chacha20poly1305

AssemblyScript implementation of chacha20poly1305, it's 20% - 60% faster compared to stablelib with no memory allocation in the middle.

This was ported from the typescript version https://github.com/StableLib/stablelib/tree/master/packages/chacha20poly1305

Usage

yarn add @chainsafe/as-chacha20poly1305

const ctx = newInstance();
const asImpl = new ChaCha20Poly1305(ctx);
const key = new Uint8Array(crypto.randomBytes(KEY_LENGTH));
const nonce = new Uint8Array(crypto.randomBytes(NONCE_LENGTH));
const plainText = new Uint8Array(crypto.randomBytes(512));
const ad = new Uint8Array(crypto.randomBytes(32))
const asSealed = asImpl.seal(key, nonce, plainText, ad);
// overwrite sealed to save memory allocation
const plainText2 = asImpl.open(key, nonce, sealed, true, ad);
expect(plainText2).to.be.deep.equal(plainText);
