Usage

import base64

// Encode / Decode (standard)
let encoded = base64.encode("Hello World")   // "SGVsbG8gV29ybGQ="
let decoded = base64.decode(encoded)!        // "Hello World"

// URL-safe (no padding, - and _ instead of + and /)
let url_encoded = base64.encode_url("Hello World")
let url_decoded = base64.decode_url(url_encoded)!

Bytes API

import base64

let encoded = base64.encode_bytes([72, 101, 108, 108, 111])  // "SGVsbG8="
let bytes = base64.decode_bytes("SGVsbG8=")!                  // [72, 101, 108, 108, 111]
