I have a class which has following __construct.
final class mydecoder {
private $td;
public function __construct($key){
/* Open the cipher */
$this->td = mcrypt_module_open(MCRYPT_BLOWFISH, '', 'ecb', '');
/* Create the IV and determine the keysize length, use MCRYPT_RAND
* on Windows instead */
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($this->td), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size($this->td);
/* Create key */
$key = substr(md5($key), 0, $ks);
/* Intialize encryption */
mcrypt_generic_init($this->td, $key, $iv);
}
}
When I call it like:
$encoder = new myfish('mykey1');
$encoder = new myfish('mykey2');
I have following problems.
Opening page for first time
construct #1 execution time: 5s
construct #2 execution time: 0s
Pressing F5
construct #1 execution time: 0s
construct #2 execution time: 14s
Pressing F5
construct #1 execution time: 5s
construct #2 execution time: 14s
Mashing F5 for 3 times (to queue)
construct #1 execution time: 15s
construct #2 execution time: 45s
It looks like it queues? How does it work? Maybe I'm not using it properly? I don't have much experience with cryptography since I never needed it before :)
