SSL Certificate Revocation is the system by which we invalidate a "no longer good" Certificate. And this week, I'm doing a free, live webinar to illustrate exactly what Certificate Revocation is, and how it works.
📅 Thursday April 4, 2024
⌚10a PDT / 1p EDT / 5pm UTC
In the session, we will cover:
- The need for Certificate Revocation
- CRLs - Certificate Revocation Lists
- OCSP - Online Certificate Status Protocol
- OCSP Stapling
Following the lecture, we'll do a live demo where we manually check the revocation status of a public website.
Expecting the session to run about 60 minutes.
Totally free. No registration required.

I'm testing new live training software, so unfortunately this session won't be live streamed to Youtube. (I'm also traveling, and don't have my live stream set up that I have at home).

Well, I ruptured my achilles tendon 🤕. Had surgery Monday, and I'm restricted to non weight bearing activities.
Which is perfect excuse for a few live streams! Starting with:
🔒🔑 Cryptography Essentials 🔑🔒

This is going to be the start of a series of live streams in which I do live teaching sessions covering most of the content in my Practical TLS course (pracnet.net/tls).
Stay tuned for more announcements with dates for the upcoming sessions.
Lesson Plan for Friday's live stream:
Hashing
Keys / Secret Keys
Symmetric Cryptography
Encryption
MAC / HMAC
Pseudo Random Function
Asymmetric Cryptography
Asymmetric Encryption
Signatures
Key Exchanges
Do you? =)
TLS is used everywhere (as it should be). It undergirds most of our network communication.
If you don't... you have three days left to take advantage of the sale for my TLS course: Practical TLS =)
Code: RAOK2024, Only $67 (normally $297).
Just a few weeks ago, I reached another milestone –- crossing 200,000 subscribers on YouTube. This feels surreal, exhilarating, and humbling.
To every single one of you, I want to say... Thank you.
Thank you for watching my videos.
Thank you for liking/subscribing.
Thank you for sharing my content with your peers.
Thank you for all the positive comments you have left.
The comments are a stream of positivity and encouragement (and the occasional inside joke 😁).
Through approximately 150k~ subscribers, I read & replied to every single comment; after that it became too difficult to keep up. But still today I _read every single comment_ and reply when I can. Your comments energize and inspire me to continue building Practical Networking.
That said, I still vividly remember the challenging, early years on Youtube -- back before I had any meaningful number of subscribers. Putting so much effort into creating videos, and receiving so few (if any!) comments. It was a soul-sucking, disheartening grind that I am so grateful to be past... so again, THANK YOU.
Therefore, in recognition of that grind, just like when I passed 100k, I want to take this moment of passing 200k to shine some light on other creators that are making great educational content.
I recently polled all of you for recommendations, the only rule was they had to have less than 200k subs on Youtube. Below is a list of creators that are making or sharing high quality educational content for you.

Each of these creators have created or shared content that I have personally benefited from. If you're looking to round out your network of quality people to follow/subscribe to, these should all be on your list.
On to 2024, and the road to 300k subscribers. Thank you all again for joining me on this journey.

The holiday season is here, and I've decided to do something different instead of the usual course discount offer.
In the spirit of gift-giving, when you buy the course for $75 (normally $297) with the coupon 'HolidayGift2023', you'll also get an additional coupon that allows you to gift the same course to a friend for free.
This means that if you team up with a friend, both of you can access the course for less than $40 each!

I'm closing in ok 200k subscribers =). Just like I did when I crossed 100k, I'd like to use this milestone to also shine some light on some lesser known creators:

And I'd love to source that list from my current audience.
Please post a comment referring me to a Youtube channel/creator you like somewhere in the IT / Tech Training space, that has less than 200k subscribers. I'd love to feature a few when I make my "I passed 200k" post shortly.
Ok, it's happening, the Black Friday 2023 sale for my Practical TLS course is live!
pracnet.net/tls to purchase, use coupon code BF2023
-- $297 course for only $50
This is *the* course if you want to really "get" how SSL & TLS work.

By popular request... I'm making a video on Layers 5, 6, and 7 of the OSI model... the forgotten layers =).

If you’ve been in the Network Engineering career field for any small amount of time, then you’ve probably been frustrated at how difficult it was to find articles and videos that were reliable, thorough, and understandable.
You found articles that were very entry level, that perhaps gave simple definitions but did not communicate enough to explain how technologies actually worked. You found articles that were overly detailed, that went into so much minutia that the original point would be lost.
The intent of the blog and video channel is to bridge that gap — providing the happy, practical medium between overly simplistic and overly detailed.
PracNet teaches in a manner that is accessible, easy to learn, and easy to pass on. By presenting complex technology simply, PracNet provides practical, immediately applicable, knowledge of the Network Engineering industry.
