HardwareRestriction

Namespace: Babel.Licensing Assembly: Babel.Licensing.dll

Defines an hardware object. The hardware restriction tie the license to a particular hardware represented by a key string. This class cannot be inherited.

public class HardwareRestriction : Restriction, IObservableObject

Inheritance

object ← Restriction ← HardwareRestriction

Implements

IObservableObject

Inherited Members

Restriction.Validate(ILicenseContext, Type, object), Restriction.Attach(IObjectListener), Restriction.Detach(IObjectListener), Restriction.Notify(params object[]), Restriction.Name, Restriction.License, Restriction.Listeners, Restriction.Id, Restriction.ExpireDate, object.GetType(), object.MemberwiseClone(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()

Examples

C#

// Creates an XML license for a specific hardware 
var license = new XmlLicense();

// Add the hardware key
// The hardware key can be generated using the 
// Babel.Licensing.HardwareId class
HardwareRestriction hardware = new HardwareRestriction();
hardware.HardwareKey = "EFP76-XAJXI-655MU-JAQVX-LGYL6";

license.Restrictions.Add(hardware);

var signer = XmlDigitalSignature.CreateFromKeyFile("Keys.snk");

string licenseXML = license.SignWith(signer)
                           .ToReadableString();

// The same license can be generated using fluent API
var signer = XmlDigitalSignature.CreateFromKeyFile("Keys.snk");
