C# 클래스 ComponentFactory.Krypton.Workspace.EncryptedLicenseProvider

Defines a .NET LicenseProvider that uses encrypted licenses generated by the Infralution Licensing System.

The Infralution Licensing System provides a secure way of licensing .NET controls, components and applications. Licenses are protected using public key encryption to minimize possibility of cracking.

Components or controls use the LicenseProviderAttribute to specify this class as the LicenseProvider

GenerateKey ( string password, string productInfo, UInt16 serialNo ) : string	Generate a new encrypted license using the given password If there is no installed license for the Infralution Licensing System then the only allowed password is "TEST" and the only allowed serial numbers are 1 or 0. To use the licensed version of this method ensure that the file Infralution.Licensing.EncryptedLicenseProvider.lic exists in the same directory as the Infralution.Licensing.dll and contains a valid license key for the Licensing System.

InstallLicense ( Type type, string licenseKey ) : EncryptedLicense	Install a license for the given type. This method is used by client applications to allow customers to register license for components. The generic Infralution.Licensing.LicenseInstallForm uses this method to install licenses. Client components may implement their own registration forms that call this method. You must call SetParameters before using this method.
SetParameters ( string licenseParameters ) : void	Set the parameters used to validate licenses created by this provider. This must be called by the client software prior to obtaining licenses using the EncryptedLicenseProvider. The parameters are generated using the Infralution License Key Generator and pasted into the calling client code.
ValidateLicenseKey ( string licenseKey ) : EncryptedLicense	Validate that the given license key is valid for the current licensing parameters This method provides a mechanism to validate that a given license key is valid prior to attempting to install it. This can be useful if you want to check the EncryptedLicense.ProductInfo before installing the license. You must call SetParameters before using this method.

GetLicenseDirectory ( System.ComponentModel.LicenseContext context, Type type ) : string	Return the directory used to store license files
GetLicenseFilePath ( System.ComponentModel.LicenseContext context, Type type ) : string	Called by GetLicenseKey to get the file path to obtain the license from (if there is no runtime license saved in the context) This can be overridden to change the file used to store the design time license for the provider. By default the the license file is stored in the same directory as the component executable with the name based on the fully qualified type name eg MyNamespace.MyControl.lic

ArrayEqual ( byte a1, byte a2 ) : bool	Are the contents of the two byte arrays equal
ArraySize ( int length ) : int	Return the array size to use when declaring an array of the given length. This is used to account for the difference between declaring VB and C# arrays and permit automatic conversion of the code to VB
FromHex ( string hex ) : byte[]	Converts a hexadecimal string into a byte array.
GetEncryptionKey ( string password ) : byte[]	Generate an 8 byte DES encryption key using the given password Only the first 7 bytes of the key returned are used. This enables us to reduce the size of the final license keys by 8 bytes.
