Hi there !
I am "baking" up a new website which will use the Windows Live ID Web
Authentification service in order to access the web site. Based on the
PHP file provided in the SDK, I made my own component which works
fairly well (it still need some optimization).
The only weird thing is that calling the function that derives the
secret key to use the service make the Controller dump disappear. I
tries everything, from changing function names, doing the logic in
startup or with a direct call... and so on. But I found that the
problem is when I try to save the deriviated key to an attribute... To
help you understand here are the two method as they are now :
function set_key()
{
$this->derive( 'SIGNATURE' );
$this->crypt_key = $this->derive( 'ENCRYPTION' );
}
function derive( $prefix = null )
{
if ( is_null( $prefix ) ) {
//THROW ERROR
}
$length = 16;
$key = $prefix . $this->app_key;
$key = mhash( MHASH_SHA256, $key );
if ( !$key || ( strlen($key) < $length ) )
{
//THROW ERROR
}
return substr($key, 0, $length);
}
If you use the code as shown above, the dump is hiden, if you comment
out the second call to derive() in the set_key() function, it is
not... but I really need them to be stored in an attribute !
Any idea on what happens ?
Thanks.
