Base64 Encode & Decode

In javascript you can easily perform base64 encode & decode using built-in functions. Javascript has 2 functions used to convert into base64 encoding or decoding.

Base64 Encoding using javascript

input = "myipv4address.com";
base64_encoded = btoa(input);
console.log(base64_encoded);

Output: bXlpcHY0YWRkcmVzcy5jb20=

Base64 Decoding using javascript

input = "bXlpcHY0YWRkcmVzcy5jb20=";
base64_decoded = atob(input);
console.log(base64_decoded);

Output: myipv4address.com

In PHP base64 encoding & decoding can performed using built-in functions.

Base64 Encoding in PHP

<?php
$str = 'myipv4address.com';
echo base64_encode($str);
?>
output: bXlpcHY0YWRkcmVzcy5jb20=

Base64 Decoding in PHP

<?php
$str = 'bXlpcHY0YWRkcmVzcy5jb20=';
echo base64_decode($str);
?>
output: myipv4address.com

Python also has built-in functions to perform base64 encode & decode.

Base64 Encode using python

import base64

message = "myipv4address.com"
base64_bytes = base64.b64encode(message.encode('ascii'))
base64_encoded = base64_bytes.decode('ascii')

print(base64_encoded)

Base64 Decode using python

import base64

message = "bXlpcHY0YWRkcmVzcy5jb20="
base64_bytes = base64.b64decode(message.encode('ascii'))
base64_decoded = base64_bytes.decode('ascii')

print(base64_decoded)

Dart also has built-in functions to convert base64 encoding & decoding.

import 'dart:convert';
import 'package:crypto/crypto.dart';

main() {
var str = "myipv4address.com";
var bytes = UTF8.encode(str);
var base64 = CryptoUtils.bytesToBase64(bytes);
print(base64);
}
