Error in Certificate Request....

Hi Experts,

I am facing problem in creating an certificate. I have created a certificate request in the notepad as below:

[NewRequest]
Subject ="CN=crm2007.vj.com"
Exportable = TRUE
KeySpec = 1
MachineKeySet = TRUE
[EnhancedKeyUsageExtension]
OID = 1.3.6.1.5.5.7.3.1

saved this file as bcmcert.inf. Now I ran the command in the command prompt....
certreq -new bcmcert.inf bcmcert.req.
This command has created bcmcert.req without any issues. Now I stared local Microsoft Certificate Services, and clicked on "Request a Certificate" -> "advanced certificate request" -> "submit a certificate request by using a base 64-encoded CMC...", copied the content of bcmcert.req into the text box, and clicked on submit. I got the below error........

Try the code below for your .inf file. If you use templates, you can add the following at the end (replace WebServer with correct template name - not template friendly name - no spaces):
[RequestAttributes]
CertificateTemplate = WebServer

Here is a link that explains everything if you need it:
http://technet.microsoft.com/en-us/library/bb663762.aspx

My example also increases your key strength from 1024 to 2048, which you should be doing these days anyways.

I assume that "certreq -new bcmcert.inf bcmcert.req. " did not have a period at the end as in the example?

Also, you might try using pkiview.msc (PKI Health Tool - available in 2003 resource kit, comes standard in 2008 renamed as Enterprise PKI). This will allow you to diagnose a number of PKI related issues quickly.

[Version]
 Signature="$Windows NT$"
[NewRequest] 
 Subject ="CN=crm2007.vj.com"
 Exportable = TRUE
 KeySpec = 1	; Valid for signing and encryption - standard for TLS / SSL
 KeyLength = 2048
 MachineKeySet = TRUE	; Stores in local computer store
 UseExistingKeySet = FALSE
 SMIME = FALSE
 PrivateKeyArchive = FALSE
 UserProtected = FALSE	; Must be set to false
 ProviderName = "Microsoft RSA SChannel Cryptographic Provider"
 ProviderType = 12
 RequestType = CMC	; Try changing this to PKCS10 instead of CMC if still having problems
[EnhancedKeyUsageExtension] 
 OID = 1.3.6.1.5.5.7.3.1	; OID for Server Authentication

Thanks for the reply. I have followed the same steps, and it is nto working. This is due different scenario I had. Let me explain you the situation.

I have installed an SAP application on my personal laptop. This application is running at 192.xx.xx.1. This application has also installed a web site on IIS 6.0 with virtual address 192.XX.XX.2 on the same laptop. Now I am calling website from IE with address http://192.XX.XX.2/default.htm. Here the IE has to start application with an SSL certificate. I created the SSL certificate serveral ways and failed. Finally, what I understood is that I am creating an SSL creating with the subject as

Subject = "CN=crm2007.vj.com", O=TRAINING....

where crm2007.vj.com is my computer name, and Workgroup name is WORKGROUP.

From documentation, I understood that CN should be the DNS or NetBIOS name. Where my system is standalone system with workgroup defined as WORKGROUP.

Have I specified the correct value to CN parameter? If not, what is the value that I should specify? Can I create SSL certificate for a workstation? If yes, how? I need help on this very badly, and I can call you and share my desktop if required. my personal mail id is chphaniv@gmail.com

Request your inputs, and Thanks for your time.

Regards,
Phani.

The CN can be netbios name, DNS name, IP address, or canonical name. DNS is most common. However, it must match what you are calling.

Since you are calling it as 192.x.x.2 that is what you need for the CN. You can get a SAN cert from many commercial CAs or from your own CA (need to enable SAN on your own CA first) - some commercial CA's don't like to issue to internal IP addresses though. I think Comodo will, but I'm not positive offhand, godaddy I've heard does not.

Also, make sure you are calling it as https:// instead of http:// since it is an SSL page.

It is generally best to use a CA signed certificate, however you can also use a self-signed cert - makecert.exe you can download from microsoft as part of the Platform SDK. Command reference is here:
http://msdn.microsoft.com/en-us/library/bfsktky3(VS.80).aspx

Download SDK here if you don't already have it:
http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=e6e1c3df-a74f-4207-8586-711ebe331cdc

example command:
makecert -n "CN=192.x.x.1" -pe -sr localmachine -ss CA -a sha1 -r CertName.cer

Since you are accessing this on the local box, you may need to look into this - not sure if it applies since it is a different IP address at least:
