Generate A Csr And Private Key
Digital ID's make use of a technology called public key cryptography, which uses public and private key files. The public key, also known as CSR, is the key that will be sent to Thawte. The private key remains on your server and should never be released into the public. Thawte does not have access to your private key. If the device on which you are generating the CSR is also the (only) device the certificate will be used, you should leave “make private key exportable” unchecked. This will prevent the certificate from being exported from the machine in an easy fashion. (It can still be sniffed from memory by an advanced attacker who has compromised the box). Create a Private Key and Certificate Signing Request (CSR) Follow these instructions to crate a private key and certificate signing request. On a SSH session to the Cortex XSOAR server, generate the private certificate by running the following command. How to generate private key and CSR from command line. This article describes how to generate a private key and CSR (Certificate Signing Request) from the command line. You may need to do this if you want to obtain an SSL certificate for a system that does not include cPanel access, such as a dedicated server or unmanaged VPS. CSR code (Certificate Signing Request) is a specific code and an essential part for the SSL activation.It contains information about website name and the company contact details. For many reasons, the code should be created on the hosting server end. 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?

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.
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.
For instructions on how to install SSL certificates, see SSL Certificate Installation Instructions & Tutorials.
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.
You can also use OpenSSL to create a certificate request for your code signing certificate.
