Hi Brian, that’s very kind - thank you very much

Thanks Marc! The way you explain the thing is excellent!

I love how well you explained everything. Thank you.

Let's Encrypt is a fantastic project! It definitely makes the internet more accessible and secure for hobbyists webmasters. Very good explanation by the way!

Agreed - and many thanks ;-)

Waoo. The first video that explains me how let’sencrypt ask DNS for verification. This video is for newest like me. Thanks

Very nice and very clear explanation around letsencrypt. Thank you. Deserves a lot more likes.

congratulations for sharing info about certificate transparency program; many people are not aware about it, and some will have a big unpleasant surprise one day (hostnames disclosure, funny "test" dns names etc.)

Hi Alex, thank you very much - one could probably talk for hours about the impacts and side effects of certificates, TLS, trusts, chains and so on ;-) But when I read about the Cert Transparency, I thought - hmmm ... If you get a cert for host1, host2... then you probably have a host 3 ;-)

Very nicely explained. Thanks a lot for your efforts.

That application/database program I am using ever since, its awesome. Thank you.

Extremely helpful video series, thank you!

His explanations are the best

Very interesting. Especially using a free wildcard cert locally. Thanks a lot!

Hi Robert, yeah - I discovered that when I tried to segregate my VLANs using a reverse proxy ;-)

Thank you very much for your great explanation.

Thank you. You explained that very well.

GREAT Video, GREAT to say the least

Great video!

Thanx Marc! I personally found the best option to automate let's encrypt wildcard cers is to maintain your own dns servers. It allow you to make any number of subdomains with DNSSEC and all the stuff.

Hi Sergey, that's definitely a good option.It does have side-effects though (such as opening access to port 53 and the like)

Hi Bruno, thank you very much for your feedback!

Great video Marc, always extremely informative thank you!!! Would you ever consider revisiting the BATMAN protocol in depth? Such as with DSA architecture or APs with no built in switch?

@OneMarcFifty

Hi Alex, many thanks. I am currently working on an episode on how to build a router with the Raspberry Pi - with regards to the question how to do VLANs without a switch. But your question inspires me to maybe do a separate episode altogether, as there are mutiple ways of doing VLANs on devices with or without switches. I might talk about BATMAN in those as well. Thanks again.

Thanks! 👍

Thanks!

Thank you very much for this video. Is it possible to run this XCA program in Docker Container? What would be the best option, in terms of security?

Interesting, great content! I happen to use the same webspace-provide like you, but I have enabled 2FA with an authenticator-app. Do you see any chance then still to do automation?

Thank you for the video ! does the wildcard option allow me to use short names without a warning ? I'm using step-ca for my homelab to automatically provides certificates for my servers

Hi Vincent. No - you will still need FQDN with these.

do you have a video explains in details about wildcard certificate ?

I'm really interested in your automation certbot script. How did you read the string for the txt record given by certbot?

@OneMarcFifty

Жыл бұрын

If you check github.com/onemarcfifty/cheat-sheets/blob/main/Certificates/ansible-playbooks/auth_hook.py then you can see that the value comes from the environment variables CERTBOT_VALIDATION and CERTBOT_DOMAIN which are set by the certbot command.

I agree with@BrianThomas - never seen anything like this before - well done sir. I wonder if you would be able to cover the X.509 certification in terms of STM32 Mbed RTOS terms of usage. I.e., would the xca tool be able to support the lwIP embedded server httpd deamon on STM32 processors. Also how can the x.509 certification be implemented on production runs of hundreds or thousands of boxes. Would every box require a seperate certificate etc. in case the vendor does not use a different private key for each product sold would the public key holders be able to hack other customers products. This is a very unclear area of discussion regarding this type of certification. Please give us your thoughts on this topic sir. Thanks

So no way to get lets encrypt certificate for internal domain other than creating own CA?

can i share my x 509 .pem certificate to my teammate? what happens if .pem certificate is publicly exposed??

how could we include our RootCA into browser by default. meaning we don't have to manually import.

You'd have to become an industry trusted certificate authority. Considering a CA can issue certificates for any domain and browsers will consider them valid, trust isn't taken lightly or given easily. The average joe will never be given this level of trust by the industry as a whole.
