# Windows certreq full response file [closed]

I'm using the Windows certreq command line tool to submit a CSR for signing to a Windows Server CA.

certreq.exe -attrib "CertificateTemplate:WebServer" -submit webapp.csr webapp.cer webapp.p7b


It's working as expected I'm getting the Base64-encoded certificate webapp.cer and the certificate with the certificate chain webapp.p7b. But the Microsoft documentation specifies that an extra parameter can be used named FullResponseFileOut which generates a Base64-encoded certificate file.

What is the purpose of this "Full Response File Out" and is there any way to display/decode it's content with OpenSSL or any tool?

You can look at them all with certutil.exe and make your own mind up though - simply pipe the outputs to a text file and read at your leisure. If the extra parameter to your command above is webapp.ful the following will allow you to read all of the files with a text editor:
certutil webapp.cer > cer.txt
