A colleague had her Windows task bar on the wrong screen, and wanted to move the task bar to the other monitor. Seems this is a little confusing in Windows. You find the option if you right click on the desktop, then click on screen resolution. You will get this dialog: First, you must click […]

Can I safely send a Certificate Request (CSR) by Email?
Yes. The CSR is your public key, which will be verified and signed by the certificate authority (CA) and returned to you afterward. It is this signed version you will then use in your application. It is useless without the private key, so even if someone makes a copy of it, they won’t be able […]
