故事起源于逛v站的求职和招人贴,每次都是一长串字符,很疑惑,不知道是邮箱,照样微信号,照样钉钉,照样QQ。
觉得像是base64,又觉得不像,由于我之前只知道图片能转成base64,没想到字符串也能转,群里一问,还确实是base64。
因而风趣的事发生了,同学们纷纭用本身最善于的言语,把base64 字符串编解码完成了一遍…
我把小伙伴们用各种方式完成的要领整顿下,有linux shell,javascript,node,python,php,java,.net。
1.shell (author: Peng Zhao)
解码:echo "a2FsZUBvdWNodGVhbS5jb20=" | base64 -d
编码:echo "kale@ouchteam.com" | base64
2.javascript (author: Kai Gao)
var encodedData = window.btoa('kale@ouchteam.com'); // 编码
var decodedData = window.atob("a2FsZUBvdWNodGVhbS5jb20="); // 解码
console.log(encodedData,decodedData)
3.nodejs (author: Kai Gao)
//base64编码
var b = new Buffer('kale@ouchteam.com');
var s = b.toString('base64')
console.log("邮箱编码:"+s)
//base64解码
var b = new Buffer('a2FsZUBvdWNodGVhbS5jb20=',"base64")
var s = b.toString();
console.log("邮箱解码:"+s)
4.python (author: Peng Zhao)
import base64
base64.b64encode("kale@ouchteam.com")
base64.b64decode("a2FsZUBvdWNodGVhbS5jb20=")
5.php (author: Chuang Shen)
<?php
$a = 'kale@ouchteam.com';
$b = base64_encode($a);//编码
echo $b;
$c = base64_decode($b);//解码
echo $c;
?>
6.java (author: Chuang Shen)
String str = "kale@ouchteam.com";
String encodeStr = new String(Base64.encode(str.getBytes()));
System.out.println(encodeStr);
String decodeStr = Base64.base64Decode(encodeStr);
System.out.println(decodeStr);
7..net (author: Peng Li)
static void Main(string[] args)
{
Console.WriteLine("输入:");
var str = Console.ReadLine();
//加密
byte[] EncryptionByte = Encoding.UTF8.GetBytes(str);
var EncryptionStr = Convert.ToBase64String(EncryptionByte);
Console.WriteLine("加密效果:" + EncryptionStr);
//解密
byte[] DecryptionByte = Convert.FromBase64String(EncryptionStr);
var DecryptionStr = Encoding.UTF8.GetString(DecryptionByte);
Console.WriteLine("解密效果:" + DecryptionStr);
}
哈哈哈 我的小伙伴们都太可爱了!
That’s it ~
