What are certificates?

[@bjornarmar2462]

Clearest explanation I’ve ever seen. Still twists my brain into a knot.

[@kiwinesss]

Same here. It doesn't matter how simply it is explained it is difficult to wrap your head around it :)

[@saltycasual4594]

Ah yes, glad i'm not alone

[@Coballes19]

I gotta say... I've been through some websites and videos trying to explain certificates. But this is the one video that explains it the most simplest and well-understandable manner.

[@itfreetraining]

Coballes19 Thanks very much, we're glad you found or videos helpful

[@RyanxDunn]

I know I'm 5 years late, but if you want simple and understandable, another person to look into is Sunny's Classroom. I haven't checked his video on certificates yet, but everything I've watched from him has clarified my confusion immensely, and his comments section is full of people saying the same thing. Just so that you have another source to go to for good informative videos :)

[@kevingrace5285]

I love when stuff is simplified. You can give me more complicated perhaps real life scenarios but make it simple at first. Thank you!

[@itfreetraining]

You're most welcome! Thanks for watching.

[@jjaroc86]

Love the training series. It's really taken everything and put it into baby steps so that anyone, even if they aren't particulary from the IT field, can easily understand these concepts. This goes for all of your videos, I love watching them all.

[@itfreetraining]

In reality, as long as you use the other key to decrypt either key can be used to encrypt. So if you use the public key to encrypt you need the private key to decrypt. If you use the private key to encrypt you would need the public key to decrypt.The public key is shared and the private is keep secret.

Thanks Anton

[@MrTomasMaliauka]

It is almost understandable. But... still many questions left unanswered and without any example. 1. Where computer gets public key to check digital signatures from? 2. Why computer has to have certificate from the organisation which issued the certificate? Why user certificate is not enough? 3. How computer know the exact algorithm to compute the certificate hash? Which hashing algorithm to use to get the hash which is digitally signed? 4. How root certificate verifies lower level user certificates? 5. What if the browser or other application is altered by malware to disable the checking of any certificates? Certificate will not help if ap app does not check them before executing the code. 6. Why XXX hacker malware can not install their own certificate to your local OS (undetectable) so that your computer OS start to trust all the cersificates issued by XXX hacker? And many other questions. Can you offer a link or a book that explains digital certificates in more details and examples?

[@itfreetraining]

1. On Windows, open certmmgr from control panel. This will show the certificates installed on the computer. Certain certificates are installed by default on Windows. 2. Using the certificates installed locally, it can check any certificate the computer it downloads and confirm that it is part of that certificate hierarchy. That is, it was issued under the root certificate, the one you have installed on your computer. 3. This information is in the certificate. 4. Certificate are issued by certificate authority. They come under the root certificate and are essentially mathematical chained to the certificate authority above it. A user would not generate their own certificate, they would get one issued from a certificate authority. Using the root certificate, they can verify the certificate is part of that hierarchy. 5. Certificate are used for secure channels. For example, for HTTPS. It could be possible I guess for malware to disable this some how making your connection insure. If this were to occur, the server could just reject the connection. 6. Yes, a hacker could do this.
