Hi, Thanks for the prompt replies. I agree signature from private key should be present in a CSR. However, as per RFC 2511, Proof Of Possession is optional though it strongly recommends to have it. I was able to create the CSR with only public key. I was unintentionally adding an extra line at the end while writing to a file. That is the reason for the error. However, i have rectified it and now i am able to view the CSR contents with openssl req command. I am yet to check if I can get a valid certificate from my CA. But thanks for the help.
