Sadly, I too will have to enter Scriptistan. Obviously, I can't check a Windows certificate store remotely from a Linux machine. Sure is dusty in here!

A longer way would be to use the string, convert it to a char array, then reverse it but that is long, ugly, and we need to use an additional variable.
We could use the wmic command to request this information from the remote machine and view it in our browser. Wenn du zum Beispiel Hilfe dabei benötigst, Text aus einer Datei zu extrahieren, kannst du einfach in das Kapitel zur Textmanipulation schauen. A leap year should be shorter!

Do you think you have to lock yourself in a basement reading cryptic man pages for months on end in order to have ninja like command line skills? The minimum width is configurable as well, so file. The tactics are easy to find, too. Yes, it would be nice.
