這是在php中的等效加密/解密函數？

Question

我在java中有這樣的代碼，我需要在PHP中的等效，我也有這個代碼在.NET中，並且工作完美，但我需要在PHP中。

public static String decrypt(String pValor) throws UnsupportedEncodingException { 

    byte vBytesDecodificados[] = null; 

    try { 

     KeySpec vClave = new DESKeySpec("MyKey".getBytes("UTF-8")); 
     SecretKey vClaveSecreta = SecretKeyFactory.getInstance("DES").generateSecret(vClave); 

     IvParameterSpec iv = new IvParameterSpec(Hex.decodeHex("1234567890ABCDEF".toCharArray())); 

     Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding"); 
     cipher.init(Cipher.DECRYPT_MODE, vClaveSecreta, iv); 

     vBytesDecodificados = cipher.doFinal(Base64.decodeBase64(pValor.getBytes())); 

    } catch (Exception e) { 

    } 

    return new String(vBytesDecodificados, "UTF-8"); 
} 

public static String encrypt(String pValor) throws UnsupportedEncodingException { 

    byte vBytesCodificados[] = null; 

    try { 

     KeySpec vClave = new DESKeySpec("MyKey".getBytes("UTF-8")); 
     SecretKey vClaveSecreta = SecretKeyFactory.getInstance("DES").generateSecret(vClave); 

     IvParameterSpec iv = new IvParameterSpec(Hex.decodeHex("1234567890ABCDEF".toCharArray())); 

     Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding"); 
     cipher.init(Cipher.ENCRYPT_MODE, vClaveSecreta, iv); 

     byte[] utf8 = pValor.getBytes("UTF8"); 
     byte[] enc = cipher.doFinal(utf8); 
     vBytesCodificados = Base64.encodeBase64(enc); 

    } catch (Exception e) { 

    } 

    return new String(vBytesCodificados, "UTF-8"); 
}

我已經知道它不是安全地使用這種方法，但是這是解決方案：

class Encriptacion { 
    private $iv = '1234567890ABCDEF'; 
    private $key = 'MyKey'; 

    function encode($str) { 
     $size = mcrypt_get_block_size(MCRYPT_DES, MCRYPT_MODE_CBC); 
     $str = $this->pkcs5Pad($str, $size); 
     $aaa = mcrypt_cbc(MCRYPT_DES, $this->key, $str, MCRYPT_ENCRYPT, $this->hex2bin($this->iv)); 
     $ret = base64_encode($aaa); 
     return $ret; 
    } 

    function decode($str) { 
     $str = base64_decode($str); 
     $str = mcrypt_cbc(MCRYPT_DES, $this->key, $str, MCRYPT_DECRYPT, $this->hex2bin($this->iv)); 
     $str = $this->pkcs5Unpad($str); 
     return $str; 
    } 

    function hex2bin($hexData) { 
     $binData = ""; 
     for ($i = 0; $i < strlen($hexData); $i += 2) { 
      $binData .= chr(hexdec(substr($hexData, $i, 2))); 
     } 
     return $binData; 
    } 

    function pkcs5Pad($text, $blocksize) { 
     $pad = $blocksize - (strlen($text) % $blocksize); 
     return $text . str_repeat(chr($pad), $pad); 
    } 

    function pkcs5Unpad($text) { 
     $pad = ord($text {strlen($text) - 1}); 
     if ($pad > strlen($text)) 
      return false; 

     if (strspn($text, chr($pad), strlen($text) - $pad) != $pad) 
      return false; 

     return substr($text, 0, - 1 * $pad); 
    } 
}
