Converts binary buffers to and from lowercase hexadecimal encoding
Package description
@aws-sdk/util-hex-encoding is a utility package from AWS SDK for JavaScript that provides functions to encode and decode hexadecimal strings. This can be particularly useful for handling binary data in a readable format.
Hex Encoding
This feature allows you to convert a Buffer or Uint8Array to a hexadecimal string. The code sample demonstrates encoding the string 'Hello, World!' into its hexadecimal representation.
const { toHex } = require('@aws-sdk/util-hex-encoding');
const buffer = Buffer.from('Hello, World!');
const hexString = toHex(buffer);
console.log(hexString); // Outputs: 48656c6c6f2c20576f726c6421Hex Decoding
This feature allows you to convert a hexadecimal string back into a Buffer. The code sample demonstrates decoding the hexadecimal string back into the original 'Hello, World!' string.
const { fromHex } = require('@aws-sdk/util-hex-encoding');
const hexString = '48656c6c6f2c20576f726c6421';
const buffer = fromHex(hexString);
console.log(buffer.toString()); // Outputs: Hello, World!The 'hex' package provides simple functions to encode and decode hexadecimal strings, similar to @aws-sdk/util-hex-encoding. It is lightweight and easy to use but does not offer the additional AWS SDK integrations.
The 'crypto-js' package offers a wide range of cryptographic functions, including hex encoding and decoding. It is more feature-rich compared to @aws-sdk/util-hex-encoding, providing additional cryptographic utilities like hashing and encryption.
The 'buffer' package is a Node.js core module that provides a way to handle binary data. It includes methods for hex encoding and decoding, similar to @aws-sdk/util-hex-encoding, but also offers a broader range of functionalities for binary data manipulation.
