If you want to convert your website from HTTP to HTTPS, you need to get a SSL certificate from a valid organization like Verisign or Thawte. You can also generate self signed SSL certificate for testing purpose.
In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with mod_ssl.
Reasons for importing keys include wanting to make a backup of a private key (generated keys are non-exportable, for security reasons), or if the private key is provided by an external source. This document will guide you through using the OpenSSL command line tool to generate a key pair which you can then import into a YubiKey.
I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. This makes it easier to identify and maintain.
First, generate a private key on the Linux server that runs Apache webserver using openssl command as shown below.
The generated private key looks like the following.
Using the key generate above, you should generate a certificate request file (csr) using openssl as shown below.
Generating a new SSH key. Open Terminal Terminal Git Bash. Paste the text below, substituting in your GitHub email address. $ ssh-keygen -t rsa -b 4096 -C ' [email protected] '. This creates a new ssh. When you're prompted to 'Enter a file in which to save the key,' press Enter. Generating a new SSH key. Open Terminal Terminal Git Bash the terminal. Paste the text below, substituting in your GitHub Enterprise email address. $ ssh-keygen -t rsa -b 4096 -C ' [email protected] '. When you're prompted to 'Enter a file in which to save the key. Github windows generate ssh key.
Adding your SSH key to the ssh-agent. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source. Apr 02, 2019 The above command kicks off the SSH Key installation process for users. The -o option instructs ssh-keygen to store the private key in the new OpenSSH format instead of the old (and more compatible PEM format). It is highly recommended to use the -o option as the new OpenSSH format has an increased resistance to brute-force password cracking. Ssh-keygen defaults to RSA therefore there is no need to specify it with the -t option. It provides the best compatibility of all algorithms but requires the key size to be larger to provide sufficient security. Minimum key size is 1024 bits, default is 3072 (see ssh-keygen(1)) and maximum is 16384. If you wish to generate a stronger RSA key pair (e.g. To guard against cutting-edge. Generate ssh public key. SiteGround uses key-based authentication for SSH. This has proven more secure over standard username/password authentication. More information on SSH keys can be found here. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account.
For testing purpose, you can generate a self-signed SSL certificate that is valid for 1 year using openssl command as shown below.
You can use this method to generate Apache SSL Key, CSR and CRT file in most of the Linux, Unix systems including Ubuntu, Debian, CentOS, Fedora and Red Hat.
Instead of signing it youself, you can also generate a valid trial SSL certificate from thawte. i.e Before spending the money on purchasing a certificate, you can also get a valid fully functional 21 day trial SSL certificates from Thawte. Once this valid certificate works, you can either decide to purchase it from Thawte or any other SSL signing organization.
This step is optional and not really required. For testing purpose, you can always use the self-signed certificate that was generated from the above step.
Go to Thwate trial certificate request page and do the following:
Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
