假设我有一个简单的文本,一杯不错的奶茶,它将与密钥12345进行XOR密码交换.

这个Java代码：

import sun.misc.BASE64Encoder;

import sun.misc.BASE64Decoder;

public class XORTest {

  public static void main(String args[]){

    String plaintext = "a nice cup of milk tea";
    String key = "12345";
    String encrypted = xor_encrypt(plaintext,key);
    String decrypted = xor_decrypt(encrypted,key);
    System.out.println("Encrypted: "+encrypted);
    System.out.println("Decrypted: "+decrypted);
  }

  public static String xor_encrypt(String message,String key){
    try {
      if (message==null || key==null ) return null;

      char[] keys=key.@R_502_294@arArray();
      char[] mesg=message.@R_502_294@arArray();
      BASE64Encoder encoder = new BASE64Encoder();

      int ml=mesg.length;
      int kl=keys.length;
      char[] newmsg=new char[ml];

      for (int i=0; i502_294@arArray();
      message = new String(decoder.decodeBuffer(message));
      char[] mesg=message.@R_502_294@arArray();

      int ml=mesg.length;
      int kl=keys.length;
      char[] newmsg=new char[ml];

      for (int i=0; i

PHP

$input = "a nice cup of milk tea";
$key = "12345";
$encrypted = XOR_encrypt($input,$key);
$decrypted = XOR_decrypt($encrypted,$key);

echo "Encrypted: " . $encrypted . "
