I am trying to understand the CSR generation process. I create a private key using Openssl tool. Then use the private key in a command to create a CSR. I know that CSR will contain a public key. Openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out servercsr.txt Note: server.key and servercsr.txt are the Private key and the CSR code files. Feel free to use any file names, as long as you keep the.key and.txt extensions. Sep 12, 2014 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 -new option indicates that a CSR is being generated.
Online CSR and Key Generator. SSL.com’s public CSR and Key Generator is currently down for maintenance as part of our website’s redesign and update. We will be back soon with a new and updated version. In the mean time, we encourage our customers to learn about generating CSRs and keys in our customer portal’s CSR Manager.
OpenSSL CSR Wizard
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.
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.
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.

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.

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.

I. Apache: Creating Your CSR with OpenSSL
Use the instructions in this section to create your own shell commands to generate your Apache CSR with OpenSSL.
Recommended: Save yourself some time. Use the DigiCert OpenSSL CSR Wizard to generate an OpenSSL command to create your Apache CSR. Just fill out the form, click Generate, and then paste your customized OpenSSL command into your terminal.
How to Generate a CSR for Apache Using OpenSSL
Openssl Create Crt And Key
If you prefer to build your own shell commands to generate your Apache CSR, follow the instructions below.
- Log in to your server via your terminal client (ssh).
- Run CommandAt the prompt, type the following command:Note: Make sure to replace server with the name of your server.
- Generate Files
- You've now started the process for generating the following two files:
- Private-Key File: Used to generate the CSR and later to secure and verify connections using the certificate.
- Certificate Signing Request (CSR) file: Used to order your SSL certificate and later to encrypt messages that only its corresponding private key can decrypt.
- When prompted for the Common Name (domain name), type the fully qualified domain (FQDN) for the site that you are going to secure.Note: If you're generating an Apache CSR for a Wildcard certificate, make sure your common name starts with an asterisk (e.g., *.example.com).
- When prompted, type your organizational information, beginning with your geographic information.Note: You may have already set up default information.
- Now, your OpenSSL .csr file is created.
- Order Your SSL/TLS Certificate
- Open the .csr file you created with a text editor.
- Copy the text, including the -----BEGIN NEW CERTIFICATE REQUEST----- and -----END NEW CERTIFICATE REQUEST----- tags, and paste it in to the DigiCert order form.
- Save Private KeySave (back up) the generated .key file. You need it later to install your SSL certificate.
- Install CertificateAfter you've received your SSL certificate from DigiCert, you can install it on your server.
II. Apache: Installing & Configuring Your SSL Certificate
If you still need to create a certificate signing request (CSR) and order your certificate, see Apache: Creating Your CSR with OpenSSL.
After we've validated and issued your SSL certificate, you can install it on your Apache server (where the CSR was generated) and configure the server to use the certificate.
How to Install and Configure Your SSL Certificate on Your Apache Server
- Copy the certificate files to your server.
- Log in to your DigiCert account and download the intermediate (DigiCertCA.crt) and your primary certificate (your_domain_name.crt) files.
- Copy these files, along with the .key file you generated when creating the CSR, to the directory on the server where you keep your certificate and key files.Note: Make them readable by root only to increase security.
- Find the Apache configuration file (httpd.conf) you need to edit.The location and name of the configuration file can vary from server to server—especially if you're using a special interface to manage your server configuration.
- Apache's main configuration file is typically named httpd.conf or apache2.conf. Possible locations for this file include /etc/httpd/ or /etc/apache2/. For a comprehensive listing of default installation layouts for Apache HTTPD on various operating systems and distributions, see Httpd Wiki - DistrosDefaultLayout.
- Often, the SSL certificate configuration is located in a <VirtualHost> block in a different configuration file. The configuration files may be under a directory like /etc/httpd/vhosts.d/, /etc/httpd/sites/, or in a file called httpd-ssl.conf.
One way to locate the SSL Configuration on Linux distributions is to search using grep, as shown in the example below.Run the following command:Note: Make sure to replace /etc/httpd/ with the base directory for your Apache installation. - Identify the SSL <VirtualHost> block you need to configure.If your site needs to be accessible through both secure (https) and non-secure (http) connections, you need a virtual host for each type of connection. Make a copy of the existing non-secure virtual host and configure it for SSL as described in step 4.If your site only needs to be accessed securely, configure the existing virtual host for SSL as described in step 4.
- Configure the <VirtualHost> block for the SSL-enabled site
- Below is a very simple example of a virtual host configured for SSL. The parts listed in blue are the parts you must add for SSL configuration.
- Make sure to adjust the file names to match your certificate files.
- SSLCertificateFile is your DigiCert certificate file (e.g., your_domain_name.crt).
- SSLCertificateKeyFile is the .key file generated when you created the CSR (e.g., your_private.key).
- SSLCertificateChainFile is the DigiCert intermediate certificate file (e.g., DigiCertCA.crt)Note: If the SSLCertificateChainFile directive does not work, try using the SSLCACertificateFile directive instead.
- Test your Apache configuration file before restarting.As a best practice, check your Apache configuration file for any errors before restarting Apache.Caution: Apache won't start again if your configuration files have syntax errors.Run the following command to test your configuration file (on some systems, it's apache2ctl):
- Restart Apache.You can use apachectl commands to stop and start Apache with SSL support.Restart Notes:If Apache doesn't restart with SSL support, try using apachectl startssl instead of apachectl start. If SSL support only loads with apachectl startssl, we recommend you adjust the apache startup configuration to include SSL support in the regular apachectl start command. Otherwise, your server may require to manually restart Apache using apachectl startssl in the event of a server reboot. This usually involves removing the <IfDefine SSL> and </IfDefine> tags that enclose your SSL configuration.
- Congratulations! You've successfully installed your SSL certificate.
Testing Your SSL/TLS Certificate Installation
- Browser Test
- For best results, make sure to close your web browser first and then re-launch it.
- Visit your site with the secure https URL (i.e., go to https://www.example.com not http://www.example.com).
- Be sure to test your site with more than just Internet Explorer. IE downloads missing intermediate certificates; whereas, other browsers give an error if all the certificates in the certificate chain aren't installed properly.
- DigiCert® SSL Installation Diagnostic ToolIf your site's publicly accessible, use our Server Certificate Tester to test your SSL/TLS certificate installation; it detects common installation problems.
Troubleshooting
- If your web site's publicly accessible, our SSL Certificate Tester tool can help you diagnose common problems.
- If you receive a 'not trusted' warning, view the certificate details to see if it's the certificate you expect. Check the Subject, Issuer, and Valid To fields.
- If it's the certificate you expect and the SSL certificate is issued by DigiCert, then your SSLCertificateChainFile is not configured correctly.
- If you don't see the certificate you expect, then you may have another SSL <VirtualHost> block before the one you recently configured.Name based virtual hosts aren't possible with https unless you use the same certificate for all virtual hosts (e.g., a Wildcard or a Multi-Domain SSL certificate).This is not an Apache limitation, but an SSL protocol limitation. Apache must send a certificate during the SSL handshake before it receives the HTTP request that contains the Host header. Therefore, Apache always sends the SSLCertificateFile from the first <VirtualHost> block that matches the IP and port of the request.
- For help moving your certificates to additional servers or across server platforms, see our OpenSSL export instructions.
- If you need to disable SSL version 2 compatibility in order to meet PCI Compliance requirements, add the following directive to your Apache configuration file:If the directive already exists, you may need to modify it to disable SSL version 2.
