PHP DES加密解密

<?php
/**
 * Class DES
 * 仅支持秘钥SIZE为8位 模式为ECB
 */
class DES {
	
	public static function encrypt($input, $key)
	{
		$block = mcrypt_get_block_size('des', 'ecb');
		$pad = $block - (strlen($input) % $block);
		$input .= str_repeat(chr($pad), $pad);
		
		return base64_encode(mcrypt_encrypt(MCRYPT_DES, $key, $input, MCRYPT_MODE_ECB));
	}

	public static function decrypt($sStr, $sKey) 
	{
		$decrypted = mcrypt_decrypt(MCRYPT_DES, $sKey, base64_decode($sStr), MCRYPT_MODE_ECB);
		$dec_s = strlen($decrypted);
		$padding = ord($decrypted[$dec_s-1]);
		$decrypted = substr($decrypted, 0, -$padding);
		
		return $decrypted;  
	}
	
}

  使用方法:

  //加密:

  $result = json_encode($data);

  $result = DES::encrypt($result, $key);
  print_r($result);
  

  //解密:
  $result = DES::decrypt($result, $key);
  print_r($result);
