PHP 3DES加密

不多说，直接上代码类

然后自行依据实际情况调用即可

PHPclass STD3Des {    public static function encrypt($str, $key='xxx') {        $message = $str;        $iv = '';        $message_padded = $message;        $message_padded = self::pkcs5_pad($message_padded, 8);        if (strlen($message_padded) % 8) {            $message_padded = str_pad($message_padded, strlen($message_padded) + 8 - strlen($message_padded) % 8, "\0");        }        //$message_padded = self::pkcs5_pad($message_padded, 8);//原来是在这打包的，运行了一下发现密文不一样，就改到上面了//        $encrypted_mcrypt = mcrypt_encrypt(MCRYPT_3DES, $key,//                self::pkcs5_pad($message, 8), MCRYPT_MODE_ECB, $iv);        $encrypted_openssl = openssl_encrypt($message_padded, "DES-EDE3", $key, OPENSSL_RAW_DATA | OPENSSL_NO_PADDING);        //return strtoupper(bin2hex($encrypted_mcrypt));        return bin2hex($encrypted_openssl);    }    public static function encrypt_ECB($str, $key) {        $message = $str;        $iv = '';        $message_padded = $message;        $message_padded = self::pkcs5_pad($message_padded, 8);        if (strlen($message_padded) % 8) {            $message_padded = str_pad($message_padded, strlen($message_padded) + 8 - strlen($message_padded) % 8, "\0");        }        //$message_padded = self::pkcs5_pad($message_padded, 8);//原来是在这打包的，运行了一下发现密文不一样，就改到上面了//        $encrypted_mcrypt = mcrypt_encrypt(MCRYPT_3DES, $key,//                self::pkcs5_pad($message, 8), MCRYPT_MODE_ECB, $iv);        $encrypted_openssl = openssl_encrypt($message_padded, "DES-EDE3", $key, OPENSSL_RAW_DATA | OPENSSL_NO_PADDING);        //return strtoupper(bin2hex($encrypted_mcrypt));        //return bin2hex($encrypted_openssl);        return base64_encode($encrypted_openssl);    }    public static function decrypt_ECB($encrypted, $key) {//数据解密        $data = base64_decode($encrypted);//        $data = $encrypted;        $decrypted_openssl = openssl_decrypt($data, 'DES-EDE3', $key, OPENSSL_RAW_DATA);        return $decrypted_openssl;    }    public static function encrypt_CFB8($str, $key, $iv) {        $message = $str;        $message_padded = $message;        $message_padded = self::pkcs5_pad($message_padded, 8);        if (strlen($message_padded) % 8) {            $message_padded = str_pad($message_padded, strlen($message_padded) + 8 - strlen($message_padded) % 8, "\0");        }        $encrypted_openssl = openssl_encrypt($message_padded, "DES-EDE3-CFB8", $key, OPENSSL_RAW_DATA | OPENSSL_NO_PADDING, $iv);        return base64_encode($encrypted_openssl);    }    public static function decrypt($encrypted, $key) {//数据解密        $data = hex2bin($encrypted);//        $data = $encrypted;        $decrypted_openssl = openssl_decrypt($data, 'DES-EDE3', $key, OPENSSL_RAW_DATA);        return $decrypted_openssl;    }    private static function pkcs5_pad($text, $blocksize) {        $pad = $blocksize - (strlen($text) % $blocksize);        return $text . str_repeat(chr($pad), $pad);    }}//$encrypted_openssl =STD3Des::encrypt('0123456789', 'test0123456789');//echo 'encrypted_openssl=='.$encrypted_openssl.'
