RequestedPastKeyReserveTime Property (ManagedSecurityGroupParameters)



OpcLabs.BaseLib Assembly > OpcLabs.BaseLib.Security.KeyManagement.Configuration Namespace > ManagedSecurityGroupParameters Class : RequestedPastKeyReserveTime Property
Amount of reserve time for which past security keys will be requested. In milliseconds.
Syntax
'Declaration
 
<DefaultValueAttribute(0)>
<UnitAttribute("ms")>
Public Property RequestedPastKeyReserveTime As Double
'Usage
 
Dim instance As ManagedSecurityGroupParameters
Dim value As Double
 
instance.RequestedPastKeyReserveTime = value
 
value = instance.RequestedPastKeyReserveTime
[DefaultValue(0)]
[Unit("ms")]
public double RequestedPastKeyReserveTime {get; set;}
[DefaultValue(0)]
[Unit("ms")]
public:
property double RequestedPastKeyReserveTime {
   double get();
   void set (    double value);
}
Remarks

Normally, RequestedPastKeyReserveTime <= MinimumPastKeyReserveTime. This is inverted in comparison to future key reserve times, but it makes sense: The past key reserve grows with time, so we can request less, but eventually it will reach the minimum reserve time.

Requirements
