Get-RevokedRequest

Get-RevokedRequest

Synopsis

Retrieves revoked certificate requests from Certification Authority (CA) database.

Syntax

Get-RevokedRequest [-CertificationAuthority] <CertificateAuthority[]> [[-RequestID] <Int32[]>] [[-Property] <String[]>] [[-Filter] <String[]>] [<CommonParameters>]

Description

Retrieves revoked certificate requests from Certification Authority (CA) database.

Since a CA server may contain many revoked certificates, you may specify various filters by using 'RequestID' or 'Filter' parameters.

Parameters

-CertificationAuthority <CertificateAuthority[]>

Specifies the Certification Authority to process. This object can be retrieved by running Get-CertificationAuthority command.

Required? True
Position? 0
Default value  
Accept pipeline input? true (ByValue, ByPropertyName)
Accept wildcard characters? False

-RequestID <Int32[]>

Use this parameter if you know desired request ID or IDs. You may specify more than one ID and command will return only failed requests with matching IDs.

If this parameter is used, 'Filter' parameter is ignored.

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

-Property <String[]>

By default, the command returns only common certificate request properties (database columns). Use this parameter to show additional properties if necessary. List of possible properties depends on CA server operating system version. To retrieve valid property list run Get-CASchema command.

In order to display all properties for output objects set this parameter to asterisk '*'. However, all property retrieval may affect Certification Authority's performance.

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

-Filter <String[]>

Specifies the query filter to restrict output objects to ones that matches query filter rule. Query filter rule consist of three components: <RequestProperty>, <comparison operator> and <value>. Query filter is composed in the following format: "<RequestProperty> <comparison operator> <value>" where:
<RequestProperty> - is a certificate request property name. To retrieve valid property list run Get-CASchema command.
<comparison operator> - specifies the logical operator of the data-query qualifier for the column.
<value> - specifies the data query qualifier applied to the certificate request property.

Possible operators are:
-eq (equal to) - the value in the <value> field equals to a value stored in the certificate request property.
-le (less or equal to) - the value in the <value> field is less or equal to a value stored in the certificate request property. See below about operator behavior with string qualifiers.
-lt (less than) - the value in the <value> field is less then a value stored in the certificate request property. See below about operator behavior with string qualifiers.
-ge (greater or equal to) - the value in the <value> field is greater or equal to a value stored in the certificate request property. See below about operator behavior with string qualifiers.
-gt (greater than) - the value in the <value> field is greater than a value stored in the certificate request property. See below about operator behavior with string qualifiers.

There are special rules when processing the following operators: '-ge', '-gt', '-le' and '-lt' with string qualifiers. In this case, CA server performs binary comparison between strings (column value and qualifier value). For example, "A" is less than "B" ("A" is placed before "B", therefore "B" is greater than "A"), "AC" is greater than "AB", "ABC" is less than "BRC".
If column value length is larger than qualifier string, a wild card is virtually added to the query qualifier value. For example, column value is "a large string" and qualifier value is "a large", then column value is greater than qualifier value. In other words, "AA" > "A" and "A" < "AA".

An example of the filter: Request.RequesterName -eq domain\username
this filter returnes requests that were requested by 'domain\username' user account. See examples section for more filter examples.

You can specify multiple filters. All filters are applied to requests with logical AND operator. This means that output requests must match all filters.

Note: wildcard characters are not supported.

Note: if 'RequestID' parameter is specified, all filters are ignored.

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

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, InformationAction, InformationVariable,
WarningAction, WarningVariable, OutBuffer, PipelineVariable and OutVariable.
For more information, see about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).

Inputs

PKI.CertificateServices.CertificateAuthority

Outputs

PKI.CertificateServices.DB.RequestRow

You can pipe this object to Remove-DatabaseRow to delete specified objects from CA database.

Examples

Example 1

PS C:\> Get-CertificationAuthority -Name "company-CA" | Get-RevokedRequest

Retrieves all revoked certificate requests from MyCA certification Authority.

Example 2

PS C:\> Get-CertificationAuthority -Name "company-CA" | Get-RevokedRequest -Property "CertificateTemplate", "RawCertificate" -Filter "RequestID -ge 100","Request.RequesterName -eq domain\administrator"

Retrieves revoked requests with RequestID greater or equal to 100 and that was submitted by 'Domain\Administrator' user account. Also this command will add CertificateTemplate and RawCertificate properties.

Example 3

PS C:\> Get-CertificationAuthority "ca01" | Get-RevokedRequest -Filter "NotAfter -lt $(Get-Date)" | Remove-Request

The command will retrieve all expired revoked certificates from CA server hosted on 'ca01' server and pipes them to Remove-Request. This example can be useful, when you CA's database size is very large and you want to reduce it's size by removing already expired revoked certificate. However you must be careful and do not remove revoked signing certificates (which were used to sign data).
