Generate One Certificate File
To generate the client certificate file and private key file in a single file, use the following command:
openssl pkcs12 -in <certificate authority file>.p12 -out test1.pem -clcerts
The command generates a single certificate file in the PEM format. In the Web Service Consumer application connection, use the single certificate file while configuring both the client certificate file and the private key file. Use the password that you provide after running the OpenSSL command to configure the Web Service Consumer application connection.
