  1. What I am trying to do is, create a CSR and with a private key that is password protected (the key). In OpenSSL I can create a private key with a password like so: openssl genrsa -des3 -out privkey.pem 2048 Is there some way I can use the key I just created and generate a CSR using the key?
  2. I'm using openssl on Mac OS X 10.9 to generate a self-signed certificate for Windows Server Remote Desktop Services. How to add extended key usage string when generating a self-signed certificate using openssl. If you are just generating a CSR with this command line then use -reqexts 'my server exts' to request that the CA later generate.
  3. As per your comment, if you do not have access to the existing private key then you can create a new private key and CSR: $ openssl req -out codesigning.csr -new -newkey rsa:2048 -nodes -keyout private.key The end results remain the same, you get a CSR and issue a new certificate.

Our OpenSSL CSR Wizard is the fastest way to create your CSR for Apache (or any platform) using OpenSSL.
Fill in the details, click Generate, then paste your customized OpenSSL CSR command in to your terminal.

Information
Making your CSR is easy!
It looks like JavaScript is disabled in your browser. If you enable JavaScript, this panel will show helpful information as you switch from field to field.
Common Name (Server Name)
The fully qualified domain name that clients will use to reach your server.
For example, to secure https://www.example.com, your common name must be www.example.com
or *.example.com for a wildcard certificate.
Although less common, you may also enter the
public IP address of your server.
Department (optional)
You can leave this field blank. This is the
department within your organization that you want
to appear on the certificate. It will be listed in the certificate's subject as Organizational Unit, or 'OU'.
Common examples: Web Administration,
Web Security, or Marketing
City
The city where your organization is legally located.
State or Province
The state or province where your organization is legally located.
Country
We guessed your country based on your IP address, but if we guessed wrong, please choose the correct country. If your country does not appear in this list, there is a chance we cannot issue certificates to organizations in your country.
Organization name
The exact legal name of your organization, (e.g., DigiCert, Inc.)
If you do not have a legal registered organization name, you should enter your own full name here.
Key
RSA Key sizes smaller than 2048 are considered unsecure.
Now just copy and paste this command into a terminal session on your server. Your CSR will be written to ###FILE###.csr.

After you've created a Certificate Signing Request (CSR) and ordered your certificate, you still need to install the SSL certificate on your server. The elder scrolls v skyrim key generator download.

Where do I paste this command?

You can run this command wherever you have OpenSSL available—most likely on your server, but you can also run it on your own computer since macOS comes with OpenSSL installed. Just make sure you keep track of your private key file after you create your CSR; you'll need that private key to install your certificate.

What happens when I run this command?

OpenSSL creates both your private key and your certificate signing request, and saves them to two files: your_common_name.key, and your_common_name.csr. You can then copy the contents of the CSR file and paste it into the CSR text box in our order form.

What kind of certificate should I buy?

If you want an SSL certificate for Apache, your best options are Standard certificates and Wildcard certificates.

A DigiCert Wildcard can protect all server names on your domain (e.g., *.example.com,). Our unlimited server license lets you protect all your servers for just one price. Many of our customers save thousands of dollars per year by using a DigiCert Wildcard certificate.

Standard certificates are able to protect one server name (e.g., mail.example.com). If you only need SSL for one hostname, a Standard certificate will work perfectly.

What If I Need Subject Alternative Names?

Multi-Domain (SAN) certificates allow you to assign multiple host names—known as Subject Alternative Names or SANs—in one certificate.

Using OpenSSL to Add Subject Alternative Names to a CSR is a complicated task. Our advice is to skip the hassle, use your most important server name as the Common Name in the CSR, and then specify the other names during the order process. Our Multi-Domain (SAN) certificate ordering process allows you to specify all the names you need without making you include them in the CSR.
