In other distributions, a basic configuration file isnât provided at all. The important field in the DN is the Common Name (CN) which should be the FQND (Fully Qualified Domain Name) of the server or the host where we intend to use the certificate with. If we purchase an SSL certificate from a certificate authority (CA), it is very important and required that these additional fields like “Organization” should reflect your organization for details. One config parameter per line is allowed in the configuration file with the parameter name followed by its value or values.

The commands below and the configuration file create a self-signed certificate (it also shows you how to create a signing request). It is used for the OpenSSL master configuration file openssl.cnf andin a few other places like SPKAC files and certificate extension files for the x509 utility. Generate a new CSR using the following command syntax. We can also create CA bundle with all the certificates without creating any directory structure and using some manual tweaks but let us follow the long procedure to better understanding. Creating your first some-domain.cnf. This will create a .key file in the folder that we just created. The ‘-new’ option, indicates that a CSR is being generated.

When OpenSSL is searching for names in the configuration file the named sections are searched first. Also, the ‘.CSR’ which we will be generating has to be sent to a CA for requesting the certificate for obtaining CA-signed SSL. This page aims to provide that. This CSR is the file you will submit to a certificate authority to get back the public cert. The OpenSSL CONF library can be used to read configuration files. Here is a general example for the CSR information prompt, when we run the OpenSSL command to generate the CSR. What we put is: If you have more than one web site address, then you need to put then in the Sample openssl config file. Note: When setting the Open SSL configuration environment variable, do not enclose the file path with quotation marks. OpenSSL Configuration File. The next item in a DN is to provide the additional information about our business or organization. NOTE: This step may not be necessary depending on the OpenSSL distribution used. A CSR is created directly and OpenSSL is directed to create the corresponding private key. From then on your certificates will load just like the commercial ones. Please note that, CSR files are encoded with .PEM format (which is not readable by the humans). $ openssl req -new -sha256 -nodes -newkey rsa:4096 -keyout example.com.key -out example.com.csr The documentation is poor, there are too many ways of doing the same thing, Copy EXAMPLE.cnf to a meaningful name, eg my-family.cnf.

Be sure to make the appropriate changes to the directories. To create, while in the 'sslcert' directory, type: openssl req -new -x509 -extensions v3_ca -keyout \ Installation and configuration of the toolkit makes sure that all needed libraries and configuration files for OpenSSL are in place. This page is the result of my quest to to generate a certificate signing requests for multidomain certificates. This CSR can be used to request an SSL certificate from a certificate authority. Below are the basic steps to use OpenSSL and create a TLS certificate request using a config file and a private key. Below is the command to create a password-protected and, 2048-bit encrypted private key file (ex. Create a text file named myserver.cnf (where myserver is supposed to denote the name/FQDN of your server) with the following content: # OpenSSL configuration file for creating a CSR for a server certificate # Adapt at least the FQDN and ORGNAME lines, and then run # openssl req -new -config myserver.cnf -keyout myserver.key -out myserver.csr # on the command line. It is in the directory SSLConfigs. Adding a CRL extension to a certificate is not difficult, you just need to include a configuration file with one line.
