Encoding a string to Base64

This feature allows you to encode a plain string into its Base64 representation. It's particularly useful for encoding data that needs to be safely transmitted over a network or stored in a way that is not human-readable.

"use strict";
const { toBase64 } = require('@smithy/util-base64');
const encoded = toBase64('Hello, world!');
console.log(encoded); // Outputs: SGVsbG8sIHdvcmxkIQ==

Decoding a Base64 string

This feature enables the decoding of a Base64 encoded string back into its original string format. It's essential for retrieving the original data from a Base64 encoded string, especially when the data needs to be processed or displayed.

"use strict";
const { fromBase64 } = require('@smithy/util-base64');
const decoded = fromBase64('SGVsbG8sIHdvcmxkIQ==');
console.log(decoded); // Outputs: Hello, world!
