Status: Open
Bug Type: mcrypt related
Operating System: SuSE Linux 9.1
PHP Version: 5.0.2
New Comment:
My error checking for -3 worked so it's setting a negative integer when
I supply an invalid $encryptionKey. However, the problem is with
returning negative integers for "unknown errors" such as an invalid
MCrypt resource. In those situations, it doesn't return a negative
integer like it's supposed to.

Reproduce code:
---------------
$returnValue =
@mcrypt_generic_init($this->encryptionDescriptor, $encryptionKey,
$this->SetRandomIv());
if (0 == intval($returnValue) && -3 !== $returnValue && -4
!== $returnValue) {
throw new Exception("<h1>\n Initialization
Failed\n</h1>\n<strong>Fatal:</strong> mcrypt_generic_init(): An
unknown error occurred : phpwebtk.cryptography.Crypt.Exception
<strong>");
} else if (-3 == $returnValue) {
throw new Exception("<h1>\n Initialization
Failed\n</h1>\n<strong>Fatal:</strong> mcrypt_generic_init(): The key
length was incorrect : phpwebtk.cryptography.Crypt.Exception
<strong>");
} else if (-4 == $returnValue) {
throw new Exception("<h1>\n Initialization
Failed\n</h1>\n<strong>Fatal:</strong> mcrypt_generic_init(): There was
a memory allocation problem : phpwebtk.cryptography.Crypt.Exception
<strong>");
} else {
$ciphertext =
mcrypt_generic($this->encryptionDescriptor, $plaintext);
mcrypt_generic_deinit($this->encryptionDescriptor);
$this->CloseModule();
}
Expected result:
----------------
I expected the $returnValue to be a negative integer since
I gave a bogus $this->encryptionDescriptor and according
to the PHP manual, mcrypt_generic_init is supposed to
return a negative integer on error.
Actual result:
--------------
$returnValue was null despite the fact that
$this->encryptionDescriptor was invalid. It showed the
warning but I want to throw my own custom exception and
use the @mcrypt_generic_init() syntax to hide the default
warning. I cannot do that if a negative integer is not
being returned upon an error.
