PKI: self-signed digital certificate?

Hello this one opens me , can you help me regarding self signed Cert for EFI?

Great video! Do you have a guide or video which details how to produce a self singed cert for internal browsing for example?

This is a truly didactic explanation. Thank you for making videos!

great video, thank you, now my understanding of CA is clear. Is there a video to understand cipher suites?

A great clarification about "Secure". Thanks

So amazing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

There is also a free alternative to third party certificates: "Let's Encrypt". Google it.
"Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. It is a service provided by the Internet Security Research Group (ISRG)."

This is what I wanted to know, Great Explanation in simple manner. Thanks

Thanks Mr. Sunny for this very simple explanation about self signed certificate. Actually I have a question here: How to check the revocation status of the self signed certificate? Who revoke the self signed certificate? thanks

That is a great explanation. Thank you

making this so easy peasy ! love this

How the self signed certificate is verified by client ? or it is not verified by client at all ?

One Doubt - Why self signed certificates are feasible for only few people

great video!!

great video!! way to go :)

what is pki ,what is its purpose can u brief it

This is just bad - self signed certificates force the user to trust you implicitly. The whole point of the root CA is that their private keys are safeguarded, and therefore the chain of trust can be trusted. For a self signed cert, all bets are off. If the private key of the cert is compromised, then anyone can impersonate the certificate owner, and issue new certificates that are now trusted by the end user. The only valid use for a self signed cert is to encrypt communications between two (backend) systems that you own yourself, and definitely not on public web.

There are surprisingly few good explanations of this coming high in the search ratings, I hope this gets views.

Hi Sunny .. I have seen all of your videos .. subscribed too 😊 .. just amazing .. could you please make videos on setting up a lab and show the concepts practically?? If possible?? ThQ
