Signing CSR which is in PKCS10

mlsario

I have created my own CA in CentOS 7.

I need to sign digital certificates. I have signed SSL certs which working fine in CentOS webservers apache and nginx.

Now I need to sign a CSR which is in pkcs10 format generated from Oracle Wallet Manager for at Oracle 11 g Server. When export OWM csr to my CentOS CA, it is not being signed using openssl tool. it gives error private key not matched.

I don't get which arguments and options to use with openssl to sign pkcs10 csr. Need your help to get it done.
