1. Jul 09, 2019  Normally, the CSR/RSA Private Key pairs on Linux-based operating systems are generated using the OpenSSL cryptographic engine, and saved as files with “.key” or “.pem” extensions on the server. But no specific extensions are mandatory for text files in Linux, so the key file may have any name and extension, or no extension at all.

  3. This command creates a new CSR (domain.csr) based on an existing private key (domain.key): openssl req -key domain.key-new -out domain.csr. Answer the CSR information prompt to complete the process. The -key option specifies an existing private key (domain.key) that will be used to generate a new CSR.

The following instructions will guide you through the CSR generation process on Apache OpenSSL. To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.

The following instructions will guide you through the CSR generation process on Nginx (OpenSSL). To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.

1. Log In

Log in to your server’s terminal via Secure Shell (SSH).

2. Run CSR Generation Command

Generate a private key and CSR by running the following command:Here is the plain text version to copy and paste into your terminal:

Note: Replace “server” with the domain name you intend to secure.

3. Enter your Information

Enter the following CSR details when prompted:

  1. Common Name: The FQDN (fully-qualified domain name) you want to secure with the certificate such as www.google.com, secure.website.org, *.domain.net, etc.
  2. Organization: The full legal name of your organization including the corporate identifier.
  3. Organization Unit (OU): Your department such as ‘Information Technology’ or ‘Website Security.’
  4. City or Locality: The locality or city where your organization is legally incorporated. Do not abbreviate.
  5. State or Province: The state or province where your organization is legally incorporated. Do not abbreviate.
  6. Country: The official two-letter country code (i.e. US, CH) where your organization is legally incorporated.

Note: You are not required to enter a password or passphrase. This optional field is for applying additional security to your key pair.

4. Copy the CSR text from the file

Locate and open the newly created CSR in a text editor such as Notepad and copy all the text including:

Note 1: Your CSR should be saved in the same user directory that you SSH into unless otherwise specified by you. Note 2: We recommend saving or backing up your newly generate “.key” file as this will be required later during the installation process.

5. Generate the order

Return to the Generation Form on our website and paste the entire CSR into the blank text box and continue with completing the generation process.

https://skyeyscience.weebly.com/blog/intel-usb-30-controller-driver-windows-7. Upon generating your CSR, your order will enter the validation process with the issuing Certificate Authority (CA) and require the certificate requester to complete some form of validation depending on the certificate purchased. For information regarding the different levels of the validation process and how to satisfy the industry requirements, reference our validation articles.

After you complete the validation process and receive the trusted SSL Certificate from the issuing Certificate Authority (CA), proceed with the next step using our SSL Installation Instructions for Apache OpenSSL.

How To Generate Private Key

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.

Note: After 2015, certificates for internal names will no longer be trusted.

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.
For instructions on how to install SSL certificates, see SSL Certificate Installation Instructions & Tutorials.

Openssl Generate Csr From Existing Private Key Number

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.

Per Year Pricing
2 Years$653 per year($1,307)(You Save 10%)
1 Year$688

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.

Per Year Pricing
2 Years$207 per year($414)(You Save 10%)
1 Year$218

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.

You can also use OpenSSL to create a certificate request for your code signing certificate.
