csr

The certificate signing request (CSR) for the certificate you want to issue. As an example, you can use the following OpenSSL command to create the CSR and a 2048 bit RSA private key.

openssl req -new -newkey rsa:2048 -days 365 -keyout private/test_cert_priv_key.pem -out csr/test_cert_.csr

If you have a configuration file, you can then use the following OpenSSL command. The usr_cert block in the configuration file contains your X509 version 3 extensions.

openssl req -new -config openssl_rsa.cnf -extensions usr_cert -newkey rsa:2048 -days 365 -keyout private/test_cert_priv_key.pem -out csr/test_cert_.csr

Note: A CSR must provide either a subject name or a subject alternative name or the request will be rejected.
