To the first part:
Openssh.exe found in apache bin directory.
Server name found in apache/conf/extra/httpd-ahssl.conf file in the virtualserver directive. In my case it is localhost.
Openssh.cnf is in apache conf directory.
Generate Key and CRT files and copy these to conf/ssl dir and restart the server.
openssl req -new -newkey rsa:2048 -sha256 -days 365 -nodes -x509 -keyout server.key -out server.crt -config "C:\wamp_p\Apache_2.4.34\conf\openssl.cnf"
To the second part (for phpmyadmin):
MySQL Server 8 has a new password authentication plugin by default. To apply the original password plugin create my.ini to the mysql dir root.
If you had already created the users you need to alter it. You can check the Password authentication plugin for user with
USE MYSQL; SELECT user,host,plugin from user;
