Modern browsers like "chrome" Chrome require you to have more secure certificates with 3072 bits / sha256 and higher encryption. In order for HAproxy to support multiple storage domains, we need to enable additional extensions and include subject alternate names to the certificate.

Instructions

Please follow Complete these steps exactlycarefully:

1. First we need to edit Edit the SSL configuration: /etc/pki/tls/openssl.cnf
   
   1. in

      In the section "[ req ]", add or

      uncomment 

      uncomment this line:
      

      Code Block
      [ req ] req_extensions = v3_req

      
      

   2. Immediately below, add the following

      just underneath

      :

      ```

      Code Block
      [ v3_req ]

      
      

      subjectAltName = @alt_names

      [ alt_names ]

      
      

      DNS.1 = example.demo.sales.local

      
      

      DNS.2 = master.acme.org

      ```

      
      

   3. Note: You can add Add as many alternative names as you wish needed to the alt_names section.
   4. You may optionally also wish to fill in (optional) Set the other defaults as desired: countryName_default , localityName_default etc, .. if you want to see sensible defaults. 

2. Generate a private key: 
   

   Code Block
   openssl genrsa -des3 -out YOURDOMAIN.key 3072

   
   

3. Generate a CSR key with the newly created private key:
   

   Code Block
   openssl req -new -key YOURDOMAIN.key -out YOURDOMAIN.csr -config /etc/pki/tls/openssl.cnf -sha256 -newkey rsa:3072

   
   

4. Generate the final certificate:
   

   Code Block
   openssl x509 -req -sha256 -days 3650 -in YOURDOMAIN.csr -signkey YOURDOMAIN.key -out YOURDOMAIN.crt -extensions v3_req -extfile /etc/pki/tls/openssl.cnf

   
   

5. Combine both YOURDOMAIN.key and YOURDOMAIN.crt into a single YOURDOMAIN.pem file and configure haproxy HAproxy to use it.
6. Now you can restart Restart the HAproxy service.
7. From a Windows Client/Server, connect with Chrome , at first it will say its an untrusted certificate, download it locally and install it by double-clicking on client or server, navigate to the secure URI with Chrome.
8. At first, it will say it's an untrusted certificate. Download the certificate locally, then double-click it to install it.
9. Restart the browser, and navigate to the secure URI, you . The browser should now see the browser accept the certificate.
