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 { core } from "ext:core/mod.js";

const crypto = core.loadExtScript("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(Option<u64>) in the extensions field of your RuntimeOptions

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

Dependencies

  • deno_webidl: Provided by the deno_webidl crate
  • deno_web: Provided by the deno_web crate

Surface

All WebCrypto entry points are implemented as methods on the Crypto / SubtleCrypto / CryptoKey cppgc-wrapped classes registered under the extension's objects = [...] list. There are no standalone ops; the per-algorithm helpers in subtle_*.rs are pure-Rust and called directly from those method bodies.
