I’m 38 years old and a newer IT professional after switching careers. I just recently earned my BS degree in IT and got hired at a major defense company. I’m watching these types of videos for better understanding of specific types of concepts covered in Security+. Also I’ve been personally using technology since the days of original Oregon Trail as a hobby. As my first ever UA-cam comment: These videos are fantastic videos. You deserve way more subscribers than you have. Fantastic explanations man. Bravo.
Hi Roger! Thank you so much for the kind note, I'm honored to be the recipient of your first UA-cam comment. =). Hope things are going well at the defense company =). Let me know if your team would benefit from in person training, I'd be happy to oblige. =)
I am a Law Student and was finding it difficult to understand the certain concepts of Information Technoloagy law involving core aspects of cybersecurity. This video simplified everything and explained articulately. Thank you to the author!
So many explanations go right over the actual essence of how these keys interact to encrypt and decrypt. Almost as if they don't even know it themselves, just regurgitating shit from a textbook. THANK YOU
Again, I am amazed about the nitty gritty details this video is providing. The author starts with basic concept and take it to another level once the basic is done. This increases our horizon in which the techniques can be used. Well done.
i dont think GPT can explain it this way this days... Cryptography is the major topic in ISS, it paves the way to understand, Authentication, Acess control and internet network security... with this regard all your explanations starting from the concept Key are paramount ! i cant thank you enough!
I first tried to study Public and Private keys encryption back in 2002 after passing my Java 2 certification, but could not understand the concept. I then kept struggling with understanding how encryption and SSL/TLS works. Today this mystery is solved forever. I would like to thank the creator of this wonderful course.
Man, you deserve a medal. I've read and watched countless sources and never understood how this worked, until listening to your words, where you specify that encrypted stuff with public|private key can "only be" decrypted by the other one (private|public) depending on the case. The most unclear part of this concept is that one of the keys can describe what the other encrypts. It is absurd I realize only now, after years of wondering. I may be wrong, but I think what makes all of this counterintuitive (not just in yours, but in literally every source I've got info about this matter) is the analogy with physical keys, that usually don't have this specific kind of property. What should have made it more intuitive, resulted in way more confusion for me. Thank you so much, this video was "the key" that unlocked in me the path to understanding.
I am taking an algorithms course where I implemented all the math for calculating RSA keys, but still could not understand how to use them. Now I get it! Thanks, this video was great!
You know why this video is the Best? Because it doesn't hide the fact you can Encrypt with public and Decrypt with private but ALSO Encrypt with private and Decrypt with public May are too scared to say that.
I was a bit confused on how encryption in TOR hidden services works, especially the part of signing the hidden service descriptor and the onion address derived from the hidden service public key, now because of this video it makes perfect sense, thank you very much for this amazing video, great work !
Thanks for the great video. I found the factors P and Q for the number 1909: P=23, Q=83. To do this, I used the "Quadratisches Sieb" factorization procedure, which operates as follows: First I calculate the square root of 1909 which gives the value "43.69". After that I set the factors P = 43 and Q = 44. Now the calculations follow. If I calculate P*Q (43*44), then this results in "1892". Since this value is smaller than "1909" I increase Q by one -> Q=45. Now I calculate again the product P*Q (43*45) -> "1935". The value is now greater than "1909", so I decrease P by the value 1 -> P=42. I follow these rules until the value 1909 is calculated. Summary: - P*Q (43*44) -> 1892 < 1909 -> Q+1 (45) - P*Q (43*45) -> 1935 > 1909 -> P-1 (42) - P*Q (42*45) -> 1890 < 1909 -> Q+1 (46) - P*Q (42*46) -> 1932 > 1909 -> P-1 (41) ..... - P*Q (23*83) -> 1909 = 1909 I hope this is helpful.
Great write up! This proves 2 things: 1. Any key can be solved via brute force 2. Brute force doesn't necessarily require trying _every_ possibility, there are shortcuts you can take as you did =) Going to pin your post, to bring more attention to your write up and hopefully your channel. Good stuff!
@@PracticalNetworking Thank you for pinning. The great thing about the algorithm is also that this can be divided into several threads very well. So you could crack your RSA-1024 key on a graphics card quickly :-)!

Thank you, David. Glad you are enjoying this content =). If you are willing... could you do me a favor? Do you mind sharing these videos on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
The best video to understand how JWT works (although jwt is not explicitly discussed in the video). Can't thank you enough for such a clear and simple explanation!!
The best explanation and video I've seen on secure communications using asymmetric and symmetric keys, the illustrations and pacing of explanations are exemplary!
You explain really well, after going through few videos and still not grasping the concept your video and explanation helped me understand this concept well. Thank you for this video.
I am currently enrolled in Cisco's cybersecurity course and I always look at this particular video whenever I get symmetric and asymmetric and public and private keys confused with one another. Very very good tutorial.
I have taken many tutorials online, watched many educational videos but your tutorial is so different. You are a great teacher sir. I dont understand how but the topic is explained in depth and at the same time in a very brief and concise way. Thank you very much! Keep up the good work!
Boy, this video indeed demonstrated the mission of the channel as stated: hitting that sweet spot between basic and too complex. I often find myself frustrated right in that "Twilight Zone", googling and switching between articles and videos (only to become more frustrated). As someone else was saying, this made JWT make sense as well...after reading through stuff that was starting nicely, bulding up nicely, only to then muddy the waters in an epico style 😁. Was tempted for the first time to read the RFC. Bookmarked, subscribed, and will certainly chek the other videos. Thanks!
The way you explain things uses the right level of simplification, to facilitate understanding, but doesn't get lost in the details. Thanks for your great work, much appreciated! (I always had challanges to understand the difference between the concept of signatures vs. bulk encryption, but this visualization of yours, with the explanation helped a lot!)
This video is awesome in explaining this concept and how hashing and encryption come together in PKI as this was what Ive been struggling to grasp in terms of the complete image! Awesome job.
Ed, you are absolutely the BEST!. I'm finishing a 2 year degree at Edmonds and feel like I've learned little (all during covid, virtual) and frequently refer back to your amazing instruction. You def have the calling of a professor (not to mention your obvious chops as an engineer).
After watching other some 100 channels vodes, I was hopeless to understand about actual tsl. Now I could easily get it at single shot about it. I knew it's always who teaches make difference but not the other way.b
This is one of the best explanation of the difficult subject.I was struggling to understand the base of this topic..Now it's cleared.Thank you very much..!!
Thank you so much, you made my day, I've been reading bunch of articles about it, there was unclear idea to me (which I can use the private key to encrypt the data and use the public one for decypt) by your video you made the pic clear to me
Thanks for all of this. Superb content and presentation! Does anyone else feel guilty when you forget to like a video as you’re gobbling this stuff up?
This channel has become my go to for catching up on stuff I haven't, previously, fully understood. The simple breakdown of the subject matter makes for easier digestion. 👏👏
I finally I understood the difference between public key and private key and their use. EVERY THING ENCRYPTED WITH A PERSON X PUBLIC KEY WILL ONLY BE DECRYPTED ONLY WITH THAT PERSON PRIVATE KEY BECAUSE HE IS THE ONLY ONE IN THE WORLD TO THAT PRIVATE KEY BECAUSE PRIVATE KEYS ARE NOT SHARED.
Best video yet, BY FAR. All well explained, and following all the principals that we should have in count when learning encryption and informatic security.
Thankyou may Allah reward you , after racking my brain telling chatglt to explain this to me and going crazy , i finally understood it alhamdulillah, couldn't have done it any better 😭👍
Really well done video. There's not so many well-made videos that take on the concept, because you can't just dip your toe in the water and experience the totality and awesomeness of encryption and how it sets the stage for what we do and use daily. I can also highly recommend Paul Turner's UA-cam videos on SSH and PKI. And then Ivan Ristić's excellent book on SSL and TLS (Bulletproof SSL and TLS - Feisty Duck publishing) - the book started off as a very good TLS 1.3 book but has transpired into something much more and is currently in its second edition (preview stage). If you truly want to get to grip with SSH and PKI - play with it on your PC. It's free and with a bit of virtualization you can toy with SSH Authentication against servers. Heck, PGP is also straight forward with GPG cli and on Windows you get Kleopatra for the GUI experience (although with GPG command line you can do a lot more like sub keys).
Ivan's book is solid. I haven't heard of Paul, just looked up a few of his videos and yes, I agree, it also looks pretty solid. Glad to be compared to such high quality sources. Thanks, CKZA10 =)
New sub here. I'm studying for the A+ after getting the Google IT Support Professional cert, and ran across your channel. It's really helping me fill in the gaps on some big topics I was confused on, and helping me understand more of the basics so I can in turn understand some of the more advanced stuff for the Network+ and Security+. I seem to be learning these concepts the way you are teaching them. Thank you.
You are a great tutor and you’ve just got a subscriber, good sir. I’ve read tens of articles about ASE and this video is way better than any of them combined (although some were more about the actual functions than the general idea)
You always know how to make life brighter for everyone you know. Thank you so much for spending your Golden time to make such useful Video. these Keys are not easy to understand and to explain but you make it so much easy to understand. Thanks, waiting for your next Video. ✌
Great job on the presentation. Very clear and concise. Loved the "tell me what you are going to tell me, tell me, then tell me what you told me" approach! For your future lessons I'd like to note a piece of feedback you might want to consider. You are using colors to highlight object differences. Consider the fact that there are color blind folks out there. Perhaps in the future in addition to colors use shapes to highlight the difference. E.g. Jim's keys could have square base, while Pam's could be round and so on...
Hi Andrey, thanks for the kind words. Glad you enjoyed it =) Great call about color blind safe graphics. I'm afraid this video is from my SSL/TLS deep dive course, and the colors end up consistent throughout the entire course -- over 800 PowerPoint slides. At this point, changing every instance of a "red" key to something with different shape would be an enormous amount of work -- something I can not take on my plate at the moment =(. You are right, though, I wish from the beginning I had created the illustrations while accounting for color blind folks.
@@PracticalNetworking Sorry, I should have been clearer. I didn't mean to redo the existing lessons. I meant for when you make new lessons in the future on w/ever subject, it's something to consider. I'm not color blind myself, but when I was watching the keys move around and color messages, I had that thought that being able to see those colors correctly helps a lot, but not everyone can see colors. Anyways, awesome course! And I really want to compliment your public speaking skills! Kudos!
