deno_crypto

This crate implements the Web Cryptography API.

Spec: https://www.w3.org/TR/WebCryptoAPI/

Usage Example

From javascript, include the extension's source, and assign CryptoKey, crypto, Crypto, and SubtleCrypto to the global scope:

import * as crypto from "ext:deno_crypto/00_crypto.js";

Object.defineProperty(globalThis, "CryptoKey", {
  value: crypto.CryptoKey,
  enumerable: false,
  configurable: true,
  writable: true,
});

Object.defineProperty(globalThis, "crypto", {
  value: crypto.crypto,
  enumerable: false,
  configurable: true,
  writable: false,
});

Object.defineProperty(globalThis, "Crypto", {
  value: crypto.Crypto,
  enumerable: false,
  configurable: true,
  writable: true,
});

Object.defineProperty(globalThis, "SubtleCrypto", {
  value: crypto.SubtleCrypto,
  enumerable: false,
  configurable: true,
  writable: true,
});

Then from rust, provide: deno_crypto::deno_crypto::init_ops_and_esm(Option<u64>) in the extensions field of your RuntimeOptions

Where the Option<u64> represents an optional seed for initialization.
