Node.js API compatibility - Crypto

The crypto API in Node.js provides a set of cryptographic functionalities to help developers secure their applications. It includes methods for hashing, encryption, decryption, and generating secure random values.

/**
 * An example of using the Node.js Crypto API in an Azion Edge Function.
 * Support:
 * - Extended by library `crypto-browserify`
 * - Implemented aditional methods:
 *  - randomUUID (named exported only)
 * @module runtime-apis/nodejs/crypto/main
 * @example
 * // Execute with Azion Bundler:
 * npx edge-functions build
 * npx edge-functions dev
 */
