About the 3DES encryption problem

I need to talk to you right now. NET, data is encrypted, but now the problem is, I use PHP encryption after processing and after the. NET encryption processing data is not equal, their code there is no problem, this can be confirmed, then my side of the encryption there is a problem, and now the specific problem is not very clear, please the great God, the following is my side of the code:

/**

* 3DES Encryption Processing class
*
* @author Fbbin fbbin@gmail.com
* @version 1.0 Beta
* @created 2014/01/07
* @logs
*/
Class Crypt3des {

/** * Encryption Required key * @var intval */protected static $key = "";/** * Static Construction initialization * * @return crypt3des */public static function I    Nstance ($key = ") {self:: $key = $key; return new Static;} /** * Encrypt String * * @return string */public function Encrypt ($input) {$size = Mcrypt_get_block_size (Mcrypt_3des, Mcryp    T_MODE_ECB);    $input = $this->PADDINGPKCS7 ($input);    $key = Str_pad (self:: $key, 24, ' 0 ');    $TD = Mcrypt_module_open (Mcrypt_3des, ', MCRYPT_MODE_ECB, ');    $iv = @mcrypt_create_iv (Mcrypt_enc_get_iv_size ($TD), Mcrypt_rand);    @mcrypt_generic_init ($TD, $key, $IV);    $data = Mcrypt_generic ($TD, $input);    Mcrypt_generic_deinit ($TD);    Mcrypt_module_close ($TD); Return Base64_encode ($data);}    /** * Decrypt String * * @return string */public function Decrypt ($encrypted) {$encrypted = Base64_decode ($encrypted);    $key = Str_pad (self:: $key, 24, ' 0 ');    $TD = Mcrypt_module_open (Mcrypt_3des, ', MCRYPT_MODE_ECB, '); $iv = @mcrypt_create_iv (Mcrypt_enc_get_iv_size ($TD), MCRYpt_rand);    $ks = Mcrypt_enc_get_key_size ($TD);    @mcrypt_generic_init ($TD, $key, $IV);    $decrypted = Mdecrypt_generic ($TD, $encrypted);    Mcrypt_generic_deinit ($TD);    Mcrypt_module_close ($TD); return $this->pkcs5unpad ($decrypted);} /** * Package Strings according to rules * * @return string */public function paddingPKCS7 ($data) {$block _size = mcrypt_get_block_size (mcrypt    _3des, MCRYPT_MODE_ECB);    $padding _char = $block _size-(strlen ($data)% $block _size);    $data. = Str_repeat (Chr ($padding _char), $padding _char); return $data;}    /** * Unpack the string according to the rules * * @return string */public function Pkcs5unpad ($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);}

}

How to use:

echo Crypt3Des::instance(base64_encode('FD3BCD75678B4BABB6E8948149CA6C91'))->encrypt('1');

The result of my side is: mzbvh6dmuxi=, and the correct value should be: sztimtsd0o;

Thank you for your advice.
