Today, the use of encryption is more important than ever for both businesses and personal use. Whether it is to protect confidential information or to promote free speech, encryption is most likely used to some extent. The idea of protecting data from unauthorized eyes goes back to the days of Julius Caesar who used the Caesar Cipher; however, it is possible that it was used even before then.
Join me for this video as we will break down the two major forms of encryption, Symmetric and Asymmetric encryption. People are most frequently using proven algorithms developed by very smart math wizards; however, it is important that you understand encryption from a high-level.

Thanks for explaining it to us, really needed the extra help.
Glad it helped and you are welcome!
Loved this. you explained is very simple and had examples who made it even easier to understand
Glad it was helpful!
You are the best man Thank you so much for this !! God Bless !!!
Glad it helped!
Really nicely explained. This is helping me for an exam I have to take.
Glad it helped and thank you for the feedback!
Hi Jon, for the last question you made, we can use Diffie-Helman key exchange in order to obtain a secret key for every individual in the symmetric encryption, am i right?
The usage really depends on what you are trying to accomplish but yes with Diffie-Hellman you can exchange a private key between two parties over symmetric encryption without prior connections/knowledge of each other.
Please assist to give key length & block size of following Asymmetric Encryption Algorithms: RSA - ECC- ELGANAL-DSA- Diffie-Hellman. thank you
I'll leave that research up to you since it can vary based on the algorithm. Thank you for watching!
I still working on my CISSP, and using 2 simulator, I have felt disappointment many times, because I did not get to pass them, even today I changed the strategic putting focus on my weaknesses!!!! During the test is possible to use other application? or the computer will be unblock only for use using the test?
Be careful doing too many practice questions because if you aren't grasping the material it won't actually help. I'm not sure why you would need access to other applications but the exam environment is locked down.
@@JonGoodCyber I am using Boson Exam and CompTIA like simulator, It is good? and beside I'm using Official Study Guide Sybex. My mother tongue is not English, that's why I thought that I could use google translate for tricking question.
Boson is the best in my opinion and the questions sometimes are even more difficult than the actual exam. I would take the exam in the language you feel most comfortable otherwise you might struggle.
great video
Glad you enjoyed it!
The only thing I don't get is how the key gets transferred in a symmetric key encryption if the key is sent in plain text(I've only heard of diffie Hellman being used in asymetric key encryption) then what's the point of symmetric key encryption Plz reply
There are several ways to exchange a symmetric key: 1. Diffie Hellman 2. Out of band by loading the key onto a USB flash drive for exchange 3. Encrypt it with another symmetric key and exchange it
This guy’s good
I'm glad that you enjoyed it.
thanks brobro
You are welcome!
Thanks for the help! but damn you speak slowly. anyone reading this use 1.5x speed so it sounds like he's speaking at a normal speed
Thank you for watching! I've definitely improved with newer videos.
Okay, first of all, why you tied to your chair ?
Luckily I wasn't actually tied to my chair! Thank you for watching.
