The node:crypto module provides cryptographic functionality that includes a set of wrappers for OpenSSL’s hash, HMAC, cipher, decipher, sign, and verify functions.

A subset of the node:crypto module is available in Workers. All APIs in the tables below with a ✅ are supported, and unless otherwise noted, work the same way as the implementations in Node.js.

The WebCrypto API is also available within Cloudflare Workers.
