What is rfc4648?

The rfc4648 npm package provides utilities for encoding and decoding data in Base16, Base32, and Base64 formats, adhering to the specifications outlined in RFC 4648.

What are rfc4648's main functionalities?

Base16 Encoding

This feature allows you to encode data into Base16 (hexadecimal) format. The code sample demonstrates encoding a Uint8Array into a Base16 string.

const rfc4648 = require('rfc4648');
const data = new Uint8Array([72, 101, 108, 108, 111]);
const encoded = rfc4648.base16.stringify(data);
console.log(encoded); // Outputs: 48656C6C6F

Base16 Decoding

This feature allows you to decode Base16 (hexadecimal) strings back into their original data format. The code sample demonstrates decoding a Base16 string into a Uint8Array.

const rfc4648 = require('rfc4648');
const encoded = '48656C6C6F';
const decoded = rfc4648.base16.parse(encoded);
console.log(decoded); // Outputs: Uint8Array(5) [ 72, 101, 108, 108, 111 ]

Base32 Encoding

This feature allows you to encode data into Base32 format. The code sample demonstrates encoding a Uint8Array into a Base32 string.

const rfc4648 = require('rfc4648');
const data = new Uint8Array([72, 101, 108, 108, 111]);
const encoded = rfc4648.base32.stringify(data);
console.log(encoded); // Outputs: JBSWY3DP

Base32 Decoding

This feature allows you to decode Base32 strings back into their original data format. The code sample demonstrates decoding a Base32 string into a Uint8Array.

const rfc4648 = require('rfc4648');
const encoded = 'JBSWY3DP';
const decoded = rfc4648.base32.parse(encoded);
console.log(decoded); // Outputs: Uint8Array(5) [ 72, 101, 108, 108, 111 ]

Base64 Encoding

This feature allows you to encode data into Base64 format. The code sample demonstrates encoding a Uint8Array into a Base64 string.

const rfc4648 = require('rfc4648');
const data = new Uint8Array([72, 101, 108, 108, 111]);
const encoded = rfc4648.base64.stringify(data);
console.log(encoded); // Outputs: SGVsbG8=

Base64 Decoding

This feature allows you to decode Base64 strings back into their original data format. The code sample demonstrates decoding a Base64 string into a Uint8Array.

const rfc4648 = require('rfc4648');
const encoded = 'SGVsbG8=';
const decoded = rfc4648.base64.parse(encoded);
console.log(decoded); // Outputs: Uint8Array(5) [ 72, 101, 108, 108, 111 ]
