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. |
May 13, 2019 There are two steps involved in generating a certificate signing request (CSR). First, you have to generate a private key, and then generate CSR using that private key. Step 1: Generate a private key. Enter the following command in the Terminal with sudo to generate a private key using RSA algorithm with a key length of 2048 bits. Generate crt file from key.
- One of the most versatile SSL tools is OpenSSL which is an open source implementation of the SSL protocol. There are versions of OpenSSL for nearly every platform, including Windows, Linux, and Mac OS X. OpenSSL is commonly used to create the CSR and private key for many different platforms, including Apache.
- Having previously generated your private key, you may generate the corresponding public key using the following command. $ openssl pkey -in private-key.pem -out public-key.pem -pubout You may once again view the key details, using a slightly different command this time. $ openssl pkey -in public-key.pem.
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.

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.

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

New: Use our command line generator
In order to gain some time, you can now generate your command line with our CSR creation assistant tool. Just copy/paste to finalize !
To install a certificate on Apache Windows, you will need a cryptographic tool to generate the private key and the CSR. To do so, you can use 'OpenSSL':Install OpenSSL on a Windows computer
1- Generate the private key
- Connect under
root
and access the setup directory of your Apache server.
It is often: - We'll place our working files here but you can choose an other repertory.
- Choose a file's name that fits you and generate the key with the following command:
- If you want this key to be protected by a password (that will be requested any time you'll restart Apache), add:
'-des3'
after 'genrsa'. - You can also enhance the quality of your key. To do so, add the instructions below after 'genrsa':
'-rand/var/log/messages'
.
It enables random numbers to be used.
Make a backup copy of the .key file!
- Protect your file with:
2- Create your certificate request (CSR)
- Use this command to generate the CSR:
- The system will then ask you to fill in fields. To do so respect instructions of the page Obtain a server certificate
Country Name (2 letter code) []: (FR in France for example)
State or Province Name (full name) [Some-State]: (your state or province name, name of your département in France)
Locality Name (eg, city) []: (the name of your city)
Organization Name (eg, company) []: (your organization name)
Organizational Unit Name (eg, section) []: (do not fill - advised - or enter a generic term such as 'IT Department'.)
Common Name (eg, YOUR name) []: (the name of the website to be secured)
Email Address []: (let blank) - Do not fill in fields such as: 'A challenge password' or 'An optional company name'
3- Finalize the order process
- Use the appropriate link to place your order on our website. See Access an order form
- Copy/paste the content of the www.example.com.csr file in the form.
Configuration and use options of OpenSSL
- To generate the CSR, OpenSSL reads openssl.cnf by default. But on some platform this file is not appropriate.
In that case you can download ours:- For Symantec or Thawte server certificates: openssl-dem-server-cert-thvs.cnf
- For TBS X509 or Sectigo server certificates: openssl-dem-server-cert.cnf
- For Certigna Server Client certificates: openssl-dem-certigna-srv-cli.cnf
- For Apache under Windows, the instructions are the same. You just need to make sure you have installed Apache with OpenSSL first.Download it here. Concerning the remaining instructions, just replaceopenssl by openssl.exe
OpenSSL and SHA256
By default, OpenSSL cryptographic tools are configured to make SHA1 signatures.
for example, if you want to generate a SHA256-signed certificate request (CSR) , add in the command line: -sha256, as in:
