what exactly is the purpose of certificates? are they all necessary? can i delete the ones with a red x next to them? or should i just leave them the **** alone?
Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols that provide security for communications over networks such as the Internet. TLS and SSL encrypt the segments of network connections at the Transport Layer end-to-end.
Several versions of the protocols are in wide-spread use in applications like web browsing, electronic mail, Internet faxing, instant messaging and voice-over-IP (VoIP).
...
Short version, they are a method of implementing security of communications over a public network.
If you delete the certificates, you will not be able to access the related service. If you never access those services, no problem.
