I'm using a self signed SSL certificate on the homepage for our prom. I know almost everybody who uses this website personally, so I can assure them that the certificate is trustworthy, even though the browser displays a warning.
The question is: If I use this self signed certificate and my classmates visit the website anyway, are they less safe from hackers, malware attacks a.s.o?
The website doesn't require highest security: The only purpose of the website is for chatting and for ordering tickets; the payment doesn't happen on the website!
When you enter a not encrypted website, no warning is displayed. Does this mean no encryption is better than self-made encryption? I don't think so!
