Check For Revoked Certificate in ASP

[AnuSumesh]

Hi,

I have developed one application which should be accessible only if valid certificate from particular CA is installed on client browser .
I am using VBscript for writing the code.
I am using Request.ClientC ertificate collection to get the details of certificate for validation purpose.
Now i want to make a check that if certificate is revoked by the CA then client should not allowed to access that application.
But i dont know the way of checking for revoked certificate using vbscript.

Can anyone help me please?

Regards,
Anu

I've never used that collection before, but you can easily list everything there with this method:[code=asp]for each x in request.clientc ertificate
response.write x & " : " & request.clientc ertificate(x) & vbNewLine
next[/code]this will at least show you what's available in the collection, odds are something will help, right?

Thanks for reply.

I am using this collection only and able to get all the details.
But this collection does not contain details about Revoked Certificate.
For "Revoked Certificate", I think we have to contact Certificate Authority to get the Certificate revokation List.
But I dont know how to contact CA using ASP(VBScript).
I have searched on google also but no help.

Thanks,
Anu
