Generate a Certificate Signing Request. Complete this form to generate a new CSR and private key.

Certificate MMC access

• CSRs are signed using the private key to prevent tampering in transit to the CA. Accordingly, you need the private key to create one. It is possible to create a CSR that has no signature, but such constructions are not common and the openssl binary itself has no provisions for creating them.
• Apr 12, 2020  Now to create SAN certificate we must generate a new CSR i.e. Certificate Signing Request which we will use in next step with openssl generate csr with san command line. root@centos8-1 certs# openssl req -new -key server.key.pem -out server.csr You are about to be asked to enter information that will be incorporated into your certificate request.

Create Csr Without Private Key

• Run the MMC either from the start menu or via the run tool accessible fom the WIN+R shortcut.
  
• Click on File - Add/Remove Snap-in.
  
• Select Certificats in the left panel and click on Add.
  
• In the new window, click on Computer Account.
  
• Select Local Computer then click on Finish.
  
• Complete the adding dialog by clicking OK.
  

Request generation

• In the certificate management console, select in the folder tree Certificates - Personnal - Certificates. In the certificate list, in the central panel, right click then select All Tasks - Advanced Operations - Create Custom Request.
  
• In the new windows, select Proceed without enrollment policy under Custom Request then click Next.
  
• Select (No Template) CNG Key as the template and PKCS #10 as the request format. Then, click Next.
  
• Develop the details by clicking the arrow and click on Properties.
  
• In the properties window, in the tab General, enter a Friendly Name that will be displayed in your certificate management interfaces and optionally, a description.
  
• In the Subject tab, in the Subject Name box, add the attributes to be added to the certificate, then click on Add to add them to the request.
  
• A standard certificate will generally contain the CN, O, L, ST, and C fields.
  
• In the Private Key tab, you can choose the CSP, the key formats, and its options.
  
• For a RSA key, we recommend a key size of 2048bits. We also reocomment the SHA256 hash algorithm for the CSR signature.
  
• You can also generate ECC keys using this tool. Attention, you will need to sign your CSR using SHA256.
  
• Once the properties dialog has been completed, you can resume the CSR generation and finish the request after having chosen a file name and directory. It is important to choose the Base 64 format.

If you want to convert your website from HTTP to HTTPS, you need to get a SSL certificate from a valid organization like Verisign or Thawte. You can also generate self signed SSL certificate for testing purpose.

In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with mod_ssl.

Key, CSR and CRT File Naming Convention

I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. This makes it easier to identify and maintain.

• Instead of server.key, I use www.thegeekstuff.com.key
• Instead of server.csr, I use www.thegeekstuff.com.csr
• Instead of server.crt, I use www.thegeekstuff.com.crt

Generate Private Key For Certificate

1. Generate Private Key on the Server Running Apache + mod_ssl

First, generate a private key on the Linux server that runs Apache webserver using openssl command as shown below.

The generated private key looks like the following.

2. Generate a Certificate Signing Request (CSR)

Using the key generate above, you should generate a certificate request file (csr) using openssl as shown below.

3. Generate a Self-Signed SSL Certificate

For testing purpose, you can generate a self-signed SSL certificate that is valid for 1 year using openssl command as shown below. Hacks cracks and key generaters for phone rescue.

You can use this method to generate Apache SSL Key, CSR and CRT file in most of the Linux, Unix systems including Ubuntu, Debian, CentOS, Fedora and Red Hat.

4. Get a Valid Trial SSL Certificate (Optional)

Instead of signing it youself, you can also generate a valid trial SSL certificate from thawte. /microsoft-office-2010-serial-key-generator.html. i.e Before spending the money on purchasing a certificate, you can also get a valid fully functional 21 day trial SSL certificates from Thawte. Once this valid certificate works, you can either decide to purchase it from Thawte or any other SSL signing organization.

This step is optional and not really required. For testing purpose, you can always use the self-signed certificate that was generated from the above step.

Go to Thwate trial certificate request page and do the following:

• Select “SSL Web Server Certificate (All servers)” under the “select your trial certificate”.
• Do not check the PKCS #7 check-box under the “configure certificate”
• Copy/Paste the *.csr file that you generate above in the textbox under “certificate signing request (CSR)”
• Click on next at the bottom, which will give you a 21-day free trial certificate.

Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
