Welches ist die äquivalente Ver-/Entschlüsselungsfunktion in PHP?

Question

Ich habe diesen Code in Java, ich brauche das Äquivalent in PHP, ich habe diesen Code in. NET auch und funktioniert perfekt, aber ich brauche in PHP.

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"); 
}

ich schon weiß es nicht sicher ist, diese Methode zu verwenden, aber dies ist die Lösung:

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); 
    } 
}
