Detailed Description

The actual code of the license class is put into an internal class and made into long functions to make it harder for the crackers to find anything meaningful after the dlls were cracked in November 2005. The obfuscation virtualization is also applied using custom attribute.

Constructor & Destructor Documentation

◆ LicenseCore()

Aspose::Pdf::LicenseCore::LicenseCore ( )

Member Function Documentation

◆ ClearLicense()

static void Aspose::Pdf::LicenseCore::ClearLicense ( )
static

◆ get_EditionType()

Aspose::Pdf::EditionType Aspose::Pdf::LicenseCore::get_EditionType ( )

Gets edition type. You can use this to enable/disable some features depending on the edition type.

◆ get_LicenseExpiry()

System::DateTime Aspose::Pdf::LicenseCore::get_LicenseExpiry ( )

This is for temporary licenses. Setter is only for unit testing.

◆ get_Products()

System::ArrayPtr<System::String> Aspose::Pdf::LicenseCore::get_Products ( )

Gets Aspose product names this license is for. You need to specify value that matches the value specified in AssemblyProduct attribute. This is used to check that the license is suitable for this product.

◆ get_SerialNumber()

System::String Aspose::Pdf::LicenseCore::get_SerialNumber ( )

Unique license number. Used to black list stolen licenses.

◆ get_SubscriptionExpiry()

System::DateTime Aspose::Pdf::LicenseCore::get_SubscriptionExpiry ( )

Gets the last date of the subscription. This is to be checked against custom attribute on the assembly that contains the relase date.

◆ GetLicenseState_ForInternalUse()

static LicenseState Aspose::Pdf::LicenseCore::GetLicenseState_ForInternalUse ( )
static

Call this from your component code to check if running evaluation version or not.

if (Aspose.Words.LicenseCore.GetLicenseState_ForInternalUse() == LicenseState.Evaluation)
InjectWatermark();

◆ GetLicenseState_ForPublicUse()

static LicenseState Aspose::Pdf::LicenseCore::GetLicenseState_ForPublicUse ( )
static

This method has to be exactly the same as GetLicenseState_ForInternalUse. It is created (and duplicated) to make hacking of Aspose licensing a little more difficult. The hacker can easily find this method and attempt to circumvent it, but it will not affect the real decision about watermark injection because it is made in GetLicenseState_ForInternalUse.

The issue was discussed and a solution proposed in https://asposeproductleads.wordpress.com/2015/08/20/license-islicensed-a-potential-security-leak/#comment-22
