Here are the steps you’ll take to generate a CSR using the OpenSSL application tool: Step 1: Install OpenSSL on your Windows PC. Step 2: OpenSSL Configuration Steps. Step 3: Generate the CSR Code. A private key is usually created at the same time that you create the CSR, making a key pair. A CSR is generally encoded using ASN.1 according to the PKCS #10 specification. A certificate authority will use a CSR to create your SSL certificate, but it does not need your private key.

SSL Certificates fall into two broad categories: 1) Self-Signed Certificate which is an identity certificate that is signed by the same entity whose identity it certifies-on signed with its own private key, and 2) Certificates that are signed by a CA (Certificate Authority) such as Let’s Encrypt, Comodo and many other companies.

Self-Signed Certificates are commonly used in test environments for LAN services or applications. They can be generated for free using OpenSSL or any related tool. On the other hand, for sensitive, public-facing production services, applications or websites, it is highly recommended to use a certificate issued and verified by a trusted CA.

The first step towards acquiring an SSL certificate issued and verified by a CA is generating a CSR (short for Certificate Signing Request).

In this article, we will demonstrate how to create a CSR (Certificate Signing Request) on a Linux system.

Creating a CSR – Certificate Signing Request in Linux

To create a CSR, you need the OpenSSL command line utility installed on your system, otherwise, run the following command to install it.

Then issue the following command to generate a CSR and the key that will protect your certificate.

where:

  • req enables the part of OpenSSL that handles certificate requests signing.
  • -newkey rsa:2048 creates a 2048-bit RSA key.
  • -nodes means “don’t encrypt the key”.
  • -keyout example.com.key specifies the filename to write on the created private key.
  • -out example.com.csr specifies the filename to write the CSR to.

Answer correctly, the questions you will be asked. Note that your answers should match information in legal documents regarding the registration of your company. This information is critically checked by the CA before issuing your certificate.

After creating your CSR, view the contents of the file using a cat utility, select it and copy it.

Then go back to your CA’s website, log in, go to the page will contain the SSL certificate you purchased, and activate it. Then in a window such as the one below, paste your CSR in the correct input field.

In this example, we created a CSR for a multiple domain certificate purchased from Namecheap.

Then follow the rest of the instructions to initiate activation of your SSL certificate. For more information about OpenSSL command, see its man page:

That’s all for now! Always remember that the first step to getting your own SSL certificate from a CA is to generate a CSR. Use the feedback form below to ask any questions or share your comments with us.

The following instructions will guide you through the CSR generation process on Microsoft IIS 8. 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. Open Internet Information Services (IIS) Manager

Click Start, Control Panel, System and Security, Administrative Tools, and then select Internet Information Services (IIS) Manager.

2. Select the server where you want to generate the certificate

In the left Connections menu, select the server name (host) where you want to generate the request.

3. Navigate to Server Certificates

Generate

In the center menu, click the Server Certificates icon under the Security section near the bottom.

4. Select Create a New Certificate

In the right Actions menu, click Create Certificate Request.

5. Enter your CSR details

In the Distinguished Name Properties window, enter in the required CSR details and then click Next.

Note: To avoid common mistakes when filling out your CSR details, reference our Overview of Certificate Signing Request article.

6. Select a cryptographic service provider and bit length

In the Cryptographic Service Provider Properties window, select Microsoft RSA SChannel Cryptographic Provider and Bit Length of 2048, then click Next.

Note: Bit Length: 2048 is the current industry standard. You may choose a larger key size, but only if you have a requirement to do so, as longer key lengths increase latency and may reduce compatibility.

7. Save the CSR

Click Browse to specify the location where you want to save the CSR as a “.txt” file and click Finish.

8. Generate the Order

Locate and open the newly created CSR from the specified location you choose in a text editor such as Notepad and copy all the text including:

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.

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. Linux generate ssh rsa key.

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 Microsoft IIS 8.
