有谁知道我如何才能找出用户证书何时到期?我知道我可以使用以下代码获取给定用户的所有证书:
Set objUserTemplate = _
GetObject("LDAP://cn=userTemplate,OU=Management,dc=NA,dc=fabrikam,dc=com")
arrUserCertificates = objUserTemplate.GetEx("userCertificate")
但是,我该如何轮询给定证书的到期日期呢?我确实在这里看到了这个 java 代码:http ://forums.novell.com/novell-developer-forums/dev-ldap/364977-q-retrieving-users-public-key-over-ldap.html ,
X509Certificate cert = ( X509Certificate )it.next();
java.util.Date expires = cert.getNotAfter();
GregorianCalendar calNow = new GregorianCalendar();
GregorianCalendar calExp = new GregorianCalendar();
calExp.setTime( expires );
//issuerDN = cert.getIssuerDN().getName();
int daysTilExp = com.willeke.utility.DateUtils.daysPast( calExp );
long diffDays = com.willeke.utility.DateUtils.diffDayPeriods( calNow,
calExp );
if( diffDays <= 0 )
{
String mex = " Will expire in: " + diffDays + " days!";
但我不确定我是否可以getNotAfter
在 VB 中使用该方法,或者我将如何去做。有没有人有任何想法?如果可能的话,我希望帮助在 VBScript/VB.Net/VBA 等中进行此查询。
我确实在这里找到了这个 VBScript 代码,它似乎正在做我想要完成的事情,但看起来相当复杂,而 java 代码看起来要简单得多。有没有一种更简单的方法可以在某种 VB 中进行此查询?

更新我确实看到我可以将证书导入到 CAPICOM对象中以返回ValidToDate属性,但是根据这里的帖子,显然它存储在 AD 中的格式是错误的格式:http://www.powershellcommunity。 org/Forums/tabid/54/aff/4/aft/1639/afv/topic/Default.aspx
有谁知道 CAPICOM 导入功能需要什么格式?
