What are @smithy/util-hex-encoding's main functionalities?

Hex Encoding

This feature allows you to convert a buffer or byte array into a hexadecimal string.

const { toHex } = require('@smithy/util-hex-encoding');
const buffer = Buffer.from('hello');
const hexString = toHex(buffer);
console.log(hexString); // Output: 68656c6c6f

Hex Decoding

This feature allows you to convert a hexadecimal string back into a buffer or byte array.

const { fromHex } = require('@smithy/util-hex-encoding');
const hexString = '68656c6c6f';
const buffer = fromHex(hexString);
console.log(buffer.toString()); // Output: hello
