Generate CSR including certificate template information
OpenSSL. The following sections describe how to use OpenSSL to generate a CSR for a single host name. If you want to generate a CSR for multiple host names, we recommend using the Cloud Control Panel or the MyRackspace Portal. Install OpenSSL. Check whether OpenSSL is installed by using the following command: CentOS® and Red Hat® Enterprise openssl req -new -newkey rsa:1024 -nodes -keyout key.pem -out req.pem Lets review the command: req activates the part of openssl that deals with certificate requests signing-new generate a new request-newkey generate a new private key; rsa:1024 1024 is the bit length of the private key. Alternative you can use 2048 and 512, for larger or The OpenSSL command below will generate a 2048-bit RSA private key and CSR: openssl req -newkey rsa:2048 -keyout PRIVATEKEY.key -out MYCSR.csr. Let’s break the command down: openssl is the command for running OpenSSL. req is the OpenSSL utility for generating a CSR.-newkey rsa:2048 tells OpenSSL to Dec 02, 2018 · openssl req -out sslcert.csr -newkey rsa:2048 -nodes -keyout private.key -config san.cnf This will create sslcert.csr and private.key in the present working directory. You have to send sslcert.csr to certificate signer authority so they can provide you a certificate with SAN.

openssl x509 issues a certificate from a CSR. This is where -days should be specified. But: openssl req -x509 combines req and x509 into one; it generates a CSR and signs it, issuing a certificate in one go. That's why req supports the -days flag, as it passes it internally to the x509 command.
