#Imageproxy

Small nodejs server for for proxing http images to https.

Cache is set to 10 days.

Usage:

```

https://imageproxy.local:8080/

```

To generate the encrypted image url you can use the following example code:

```php

class Crypto

{

    private $encryptKey = 'MySecretKey12345';

    private $iv = '1234567890123456';

    private $blocksize = 16;

    public function decrypt($data)

    {

        return $this->unpad(mcrypt_decrypt(MCRYPT_RIJNDAEL_128,

            $this->encryptKey,

            hex2bin($data),

            MCRYPT_MODE_CBC, $this->iv), $this->blocksize);

    }

    public function encrypt($data)

    {

        //don't use default php padding which is '\0'

        $pad = $this->blocksize - (strlen($data) % $this->blocksize);

        $data = $data . str_repeat(chr($pad), $pad);

        return bin2hex(mcrypt_encrypt(MCRYPT_RIJNDAEL_128,

            $this->encryptKey,

            $data, MCRYPT_MODE_CBC, $this->iv));

    }

    private function unpad($str, $blocksize)

    {

        $len = mb_strlen($str);

        $pad = ord( $str[$len - 1] );

        if ($pad && $pad < $blocksize) {

            $pm = preg_match('/' . chr($pad) . '{' . $pad . '}$/', $str);

            if( $pm ) {

                return mb_substr($str, 0, $len - $pad);

            }

        }

        return $str;

    }

}

$crypto = new Crypto();

$url = 'http://i.imgur.com/Ssiz30z.png';

$encrypted = $crypto->encrypt($url);

echo '';

```
