<p class="MsoNormal">Hi,<br>
I have the public key of the client but not the private key. I am required<br>
to generate a CSR with only public key. I understand private key is required<br>
for Proof of Possession. However, as per my requirement I am supposed to<br>
create CSR only with public key and my CA would create a certificate. <br>
<br>
I was able to create a CSR with CX509CertificateRequestCertificate and<br>
CX509Enrollment classes using the available public key. When I try to read<br>
the contents the of CSR in openssl (i used this command: openssl req -in<br>
client.csr -noout -text) i get "unable to load X509 request". <br>
<br>
Is this happening because the CSR does not contain the signature of private<br>
key or the CSR is faulty.<br>
<br>
Kindly help me.<br>
<br>
Regards,<br>
Bharathi<br>
