Another option is to set the SLL off, eliminating the need for a security certificate (a less recommended option).
To do this, run the following command::
git config --global http.sslVerify "false"
When working with SourceTree software (GIT Graphic Client, link), You can also specify in the settings not to use ssl - then there is no need to install the certificate,
The check will be done when entering the menu Tools > Options > Git Select Disable SSL certificate validation.
