How does node-forge.util work?

node-forge is a cryptographic library for Node.js and the browser, and node-forge.util provides a variety of utility functions. It includes functions for converting between different data formats, encoding and decoding data to and from various formats, generating random bytes, encoding and decoding base64, hex, and binary data, and parsing and generating ASN.1 structures. These functions can be used to help with cryptographic operations such as generating keys, encrypting and decrypting data, and signing and verifying digital signatures.

const forge = require("node-forge");

const str = "Hello, World!";

const encodedStr = forge.util.encode64(str);

console.log(encodedStr); // 'SGVsbG8sIFdvcmxkIQ=='

In this example, we first require the node-forge library. We then define a string that we want to encode in base64. We use the forge.util.encode64() function to encode the string, and store the result in the encodedStr variable. Finally, we log the encoded string to the console.
