Steps required to use the HTTPS protocol.

Before you can start using the HTTPS protocol to communicate with a WRTP server, you need to create, install, and bind certificates.

Creating certificates

To create 2 debug certificates for testing the HTTPS protocol, you need to do the following:

1). Installing mkcert.exe

• open https://github.com/FiloSottile/mkcert/releases
• download the mkcert-v1.4.4-windows-amd64.exe file to the "C:\Program Files\mkcert" folder (create this folder) and rename it to mkcert.exe.
• add "C:\Program Files\mkcert" to PATH (system variables):
  Settings -> System -> About -> Advanced system settings -> Enviroment variables -> System variables\Path: press "Edit..." -> Press "New" -> put "C:\Program Files\mkcert" -> press OK -> press OK -> press OK -> Close Settings.About

2). Creating CA certificate (<user name> is name of curent user).

• remove old CA certificate from "C:\Users\<user name>\AppData\Local\mkcert" folder
• open Windows console (command prompt or Windows terminal) with administrator rights
• in the console window (header "Administrator: Command") enter:

  mkcert -install
  > Created a new local CA
  In "Security Warning" Dialog : press Yes
  > The local CA is now installed in the system trust store!

• The files "rootCA.pem" and "rootCA-key.pem" should have been created in the "C:\Users\<user name>\AppData\Local\mkcert" folder. Move them to some folder where you will store your certificates.

3). Creating work certificate cert.my for 4 names.
NOTE. IP address 192.168.1.999 is used as server IP address, please change it to your real IP address.

• in the console window (header "Administrator: Command") enter
  

  mkcert cert.my localhost 127.0.0.1 ::1 192.168.1.999   > Created a new certificate valid for the following names
  > - "cert.my"
  > - "localhost"
  > - "127.0.0.1"
  > - "::1"
  > - "192.168.1.999"
  > The certificate is at "./cert.my+4.pem" and the key at "./cert.my+4-key.pem"

• The files "cert.my+4.pem" and "cert.my+4-key.pem" should have been created in the "C:\Windows\System32" folder. Move them to some folder where you will store your certificates.

4). Convert .pem files to .pfx files using the certutil tool.

• rename your .pem files:

  rootCA.pem -> rootCA.cer
  rootCA-key.pem -> rootCA.key
  cert.my+4.pem -> cert.my+4.cer
  cert.my+4-key.pem -> cert.my+4.key

• In the console window (header "Administrator: Command"), go to the folder containing the certificates:

  cd <folder with certificates>

• convert rootCA.cer and rootCA.key files to rootCA.pfx

  certutil -MergePFX rootCA.cer rootCA.pfx
  > Signature test passed
  > Enter new password for output file rootCA.pfx:
  > Enter new password:
  ******<Enter>
  > Confirm new password:
  ******<Enter>
  > CertUtil: -MergePFX command completed successfully.
The file "rootCA.pfx" should have been created in the <folder with certificates>.

• convert cert.my+4.cer and cert.my+4.key files to cert.my+4.pfx

  certutil -MergePFX cert.my+4.cer cert.my+4.pfx
  > Signature test passed
  > Enter new password for output file cert.my+4.pfx:
  > Enter new password:
  ******<Enter>
  > Confirm new password:

 ******<Enter>

  > CertUtil: -MergePFX command completed successfully.
The file "cert.my+4.pfx" should have been created in the <folder with certificates>.
