Certificates from Scratch - X.509 Certificates explained

You saved me 200 USD. Thanks so much!

Great content and presentation. Not only that, you just seem like a genuinely nice person. Subscribed.

Hi, thanks for the video. I was following your instruction using XCA tool but it doesn't show the treeview for some reason. There is a plain view/tree view button but it doesn't show the tree view either. Not sure what I am doing wrong.

Csr has private and public key??? Does CA sign the certificate with servers private key? Or servers private and public key???

well explained, thanks

GREAT to say the least, watched so many videos but the concents u cleared, WoW. howcome this is all free ? any place I can donate ?

Too many adds

Well explained, I am getting more and more understanding of certificates. One point I do not understand is about X509 is the naming standard or what kind it is.

Awesome video, incredibly helpful, thankyou!

that is amazing !

Marc my friend, this is an outstanding video! Wow, I wish I had seen this about 2 years ago. Now I totally understand certificates. Thank you so very much! You are an excellent teacher!

Thanks Marc!

Really awesome explanation. I've watched many of these tutorials and this is the best.

You did a great job explaining this while showing the video the whole process so everybody can follow all the use cases and security concerns. Thank you so much!

Amazing video thanks for share all your knowledge, in this simple way, you makes look all so easy and simple...

i've been looking for good explanation of that topic for a while. This is incredible good one. Thank you!

Thank you so much, it's very clear now :)
You are a wonderful teacher

Thanks this was really helpfull!

I learned a lot from the info you provided. CA and CA. Best of the best. Thank you sir☺☺

That bass is amazing

In the first part of the video where you download a certificate in chrome, you mention that you are downloading it in pkcs7 format. Is this format just the default in Chrome, or did you do something in Chrome to select the format?

Hi Marc! Excellent video as usual, thanks for the tidy knowledge!
Could you explain how to apply this solution to remote access OpenWrt?

Really well done, thank you so much and kudos for your channel

This is a superb video and very needed.

About 3 years ago I was trying to deploy LE certs on my lan via the dns challenge. It took me about a week to get this done, because this method wasn't really all that popular back then and the documentation on how to exactly do this was quite sparse. Today dns challenge is supported by stuff like traefik or nginx proxy manager so setting this up has never been easier.

Please do video on Tailscale on OpenWRT

I've always thought of a certificate as being a public key (with private key optionally included, if you have it) that has additional "properties", including proof of who issued the certificate, and what the certificate can be used for. The whole topic of what a certificate can be used for is confusing. I know about web services and code signing, but there seems to be a lot of other uses that I'm not so familiar with.

Thank you so much Marc. I think your explanation is the simplest and clearest one I've ever dealt with.
I don't see the time when you will public next episodes.

Amazing class as usual Marc,

Thanks!!

Juan.

Great vid! I hope in the future you might want to explain how to use/setup SCEP and OCSP. I've been struggling to use openssl for signing certs for my WPA2 enterprise at home. It worked okay last year but this year my iOS phone does not want to trust the certificate while it does have the CA cert pushed and trusted via MDM.

Great job again Marc ! I can't wait for the next episode on the keys management, I'm struggling with that for month.

thx Mark... as always... high value information... 🙂;-)

Big brother coming if we give all authority, to government with a blind trust. Trust is paramount. how many still have absolute trust in all that is government given their performance over the last 3 years, and still is ongoing to this day,

Nice! Marс, you have a talent to explain complex things in simple terms

Always love when I see a new video drop, these are gold

This is fantastic! Thank you for making the topic so easy to understand. Certificates are certainly something I struggle with a lot!

you are born to teach ! a great video and up to your usual, fantastically high standards... looking forward to the continuation of this series... many thanks Marc.

While I understand the certificates now, I should have had this video on my playlist ~5 years ago. This is excellent. I'll use your channel to recommend to my team - your IPv6 videos rock, so does your OpenWRT tutorials. Keep it up! Thanks for the effort.

What a coincidence! I was, this morning, looking at possibilities of using Certificates for authentication on SSH connection. And you start a new serie on Certificates right at that time!!! I'm SOOO looking forward to see the rest of the serie! Thanks!

Practical approach and clear as always. Thank you.

Excellent, there are not many well-explained X.509 certificate videos online, this is super valuable, and thank you for putting this series together, looking forward to the next one.

When is the next episode up? Tomorrow?
Excellent content as usual!
