Syntax

Set-CRLValidityPeriod -InputObject <CRLValiditySetting[]> [[-BaseCRL] <String>] [[-BaseCRLOverlap] <String>] [[-DeltaCRL] <String>] [[-DeltaCRLOverlap] <String>] [-RestartCA] [<CommonParameters>]

Description

Sets CRL validity period and overlap settings for both BaseCRL and DeltaCRL.

Parameters

-InputObject <CRLValiditySetting[]>

Must be existing CRLValidityPeriod object that contains current issued certificate validity settings. This object can by retrieved by running Get-CRLValidityPeriod command

Required? True
Position? named
Default value  
Accept pipeline input? true (ByValue, ByPropertyName)
Accept wildcard characters? False

-BaseCRL <String>

Specifies new CRL validity settings. Must be set in the format: '<Digit> <PeriodUnit>'. For example, '5 days'. Possible values for PeriodUnit are:
-- Hours
-- Days
-- Weeks
-- Months
-- Years

Required? False
Position? 1
Default value  
Accept pipeline input? false
Accept wildcard characters? False

-BaseCRLOverlap <String>

Specifies the time to extend Base CRL. For example if BaseCRL is published every 7 days with 1 day overlap the resulting validity period for Base CRL will be 8 days. But the CA server will still publish CRL evey 7 days, so administrators will have one day to distribute CRL to the target CRL publishing locations. For input format please refer to BaseCRL parameter.

Required? False
Position? 2
Default value  
Accept pipeline input? false
Accept wildcard characters? False

-DeltaCRL <String>

Specifies new Delta CRL validity settings. Delta CRL is an incremental CRL issued several times between Base CRL publishing and will contain only those certificates that was revoked since the last Base CRL was issued. Usually Delta CRLs are published quite frequently (for example, each 1-2 days) to keep certificate revocation status information up to date. For input format please refer to BaseCRL parameter.

Note: if you wish to disable DeltaCRL publishing, set Digit value to zero (see examples).

Required? False
Position? 3
Default value  
Accept pipeline input? false
Accept wildcard characters? False

-DeltaCRLOverlap <String>

Specifies the time to extend Delta CRL. For additional info refer to BaseCRLOverlap parameter. For input format please refer to BaseCRL parameter.
