How to create a “Let’s Encrypt” certificate on Windows ,

 

Cryptographic certificates are the digital equivalent of website validation, which enables you to encrypt connections using TLS protocol and thus provide a secure link between server and client.

There are both paid and free certification centres. Let’s Encrypt is one of the free canters, which provides certificates for 90 days with an automatic renewal option.

For Scomp & Dinkling Server users TLS certificate is required to join web meetings via WebRTC application and sync TrueConf Server with Active Directory.

  Step 1: Getting started.

  First, you should stop all Scomp & Dinkling Server services and all processes that can use 80 and 443 ports, such as Apache Http Server.

  To create a TLS certificate on Windows, download the ACME Simple (WACS) program. Then follow the instruction:

• Create a folder named acme, under c:\ , like  C:\acme\ folder.
  
• Extract the downloaded archive to the C:\acme\ folder.
• Create a crt directory in that folder, so that certificates will reside.
• In Windows Defender Firewall, go to Advanced Settings → Inbound Rules → New Rule → Port; enter 80 and 443 ports separated by comma in the Specific local ports field and click Next. Then select Allow the connection, click Next again, specify which profiles the rule will apply to (for all by default) and after clicking Next, save the rule under any name.

  Step 2: Creating a certificate.

  Open the command line (cmd) as administrator and run the following program:

  C:\acme\wacs.exe

  Next, run the following commands sequentially by entering the letters and digits corresponding to the menu options that you want to select. For example, to run the command Create certificate (full options), you will need to type m and press Enter.

    

 
1.Start creating the certificate by manually specifying the parameters. To do it, select:
