Alternatively, you can generate your own private CA certificate and key, using a tool such as genkey found in the crypto-utils package in Red Hat Enterprise Linux. This certificate and key enables you to create SSL keys and certificates for the CDS, as well as sign the entitlement certificates for the clients to access the CDS instances. How can I find the private key for my SSL certificate. If you just got an issued SSL certificate and are having a hard time finding the corresponding private key, this article can help you to find that one and only key for your certificate.
Aug 01, 2014 This tutorial provides an approach on how to set up Secure Sockets Layer (SSL) communication cryptographic protocol on Apache Web Server installed in Red Hat Enterprise Linux/CentOS 7.0, and generate self-signed Certificates and Keys with the help of a bash script which greatly simplifies the entire process. Step 1: Install and Configure Apache. Can I generate a new private key for my SSL certificate? Since a public key with the additional information (i.e., domain name and administrative contact information) must be signed by a trusted certificate authority in order to make it applicable and legitimate for securing communication with your server, it wouldn’t make much sense if we. I'm adding HTTPS support to an embedded Linux device. I have tried to generate a self-signed certificate with these steps: openssl req -new cert.csr openssl rsa -in privkey.pem -out key.pem o.
CSR stands for ‘Certificate Signing Request’, that is generated on the server where the certificate will be used on. A CSR contains information about to your organization and domain name, locality, and country and a public key that will be included in your certificate.
This article has 3 methods to create CSR (Certificate Signing Request) on Linux systems. You can choose any one of below methods. All methods will do the same task, only they have a detailed explanation.
Method 1 – Using Single Command
We can create CSR using the single command like below. But make sure you have installed OpenSSL package on your system. The below command will first create a private key and then generate CSR. This command will also require few details as input.
Method 2 – Short Instructions
Below are three simple commands to generate CSR. You may also use detailed instructions to do it.
Method 3 – Detailed Instructions
Step 1: Install Required Packages.
In order to generate CSR, you required OpenSSL to be installed on your system. If it is not already installed use below command to install it.
Step 2: Generate Key for your Domain.
Firstly you required root access to generate a key file. So login as root and use below command to generate a key.
Sample output:
At the end of the command, it showing 2048, which is the length of the key in bits. Most of CA required 2048 bit length keys. Above command will create a key file tecadmin.net.key, which is used in step 3.
Step 3: Generate CSR for your Domain using Key.
After generating a key, next steps are to generate CSR for the domain. Use below command to generate CSR file, This command will prompt for your organization and common name, locality, email, and country. Common Name must be the same as your domain name.
Sample Output:
Above command will generate a file tecadmin.net.csr in the current directory, Use this file to order your SSL from CA (Certificate Authority).

SSL (Secure Sockets Layer) is a cryptographic protocol that allows secure data flow between a server and its clients using symmetric/asymmetric keys by using a digital certificate signed by a Certificate Authority (CA).
Requirements
This tutorial provides an approach on how to set up Secure Sockets Layer (SSL) communication cryptographic protocol on Apache Web Server installed in Red Hat Enterprise Linux/CentOS 7.0, and generate self-signed Certificates and Keys with the help of a bash script which greatly simplifies the entire process.
Step 1: Install and Configure Apache SSL
1. To enable SSL on Apache HTTP Server use the following command to install SSL Module and OpenSSL tool-kit which is needed for SSL/TLS support.
Install SSL Module
2. After SSL module has been installed, restart HTTPD daemon and add a new Firewall rule to ensure that SSL port – 443 – it’s opened to outside connections on your machine in listen state.
3. To test SSL connection, open a remote browser and navigate to your server IP address using HTPS protocol on https://server_IP.
Test SSL Connection
Step 2: Create SSL Certificates and Keys
4. The previous SSL communication between the server and client was done using a default Certificate and Key automatically generated on installation. In order to generate new private keys and self-signed certificates pairs create the following bash script on a executable system path ($PATH).
For this tutorial /usr/local/bin/ path was chosen, make sure the script has executable bit set and, then, use it as a command to create new SSL pairs on /etc/httpd/ssl/ as Certificates and Keys default location.

Use the following file content.
5. Now make this script executable and launch it to generate a new pair of Certificate and Key for your Apache SSL Virtual Host.
Fill it with your information and pay attention to Common Name value to match your server FQDN or in case of Virtual Hosting to match the Web address you will be accessing when connecting to a secure website.
Enter SSL Information
6. After the Certificate and Key are generated, the script will present a long listing of all your Apache SSL pairs stored in /etc/httpd/ssl/ location.

7. Other approach on generating SSL Certificates and Keys is by installing crypto-utils package on your system and generate pairs using genkey command, which can impose some problems especially when used on a Putty terminal screen.
So, I suggest to use this method only when you are directly connected to a screen monitor.

8. To add the new Certificate and Key to your SSL website, open your website configuration file and replace SSLCertificateFile and SSLCertificateKeyFile statements with the new pairs location and names accordingly.

9. If the Certificate is not issued by a trusted CA – Certification Authority or the hostname from certificate does not match the hostname who establish the connection, an error should appear on your browser and you must manually accept the certificate.

That’s it! Now you can use apache_sslas a command line on RHEL/CentOS 7.0 to generate as many pairs of self-signed Certificates and Keys you need, and all will be kept on /etc/httpd/ssl/ path with the Key file protected with 700 permissions.
