4:47 secrets are encrypted with Public keys and decrypted by Private keys.... The other way around would expose the secret.

Why no one else in the earth has explained this to me this very simple way? 90k college loan and still watching youtube. Thank you IBM and the gentleman on the right. You are such an awesome free thinking teacher

[NassimDhaher]

I know PKI but keep forgetting it, once or twice a year I come to these videos to remind me. Thanks for the objective content.

This was one of the best explanations of PKI that I've heard. Amazing job guys 👏

Observation that I found amusing. In order for their writing to be read by us, they rendered the video horizontally reversed. But here's the cool thing. The guy on the left was so committed to the reversal process, he swapped his wedding ring to his right hand, so it would show left in the video. I pose this concept for discussion and debate. ;)

[manawardhana]

Simplicity and brevity at their best! Thank you!

Studying Cyber Security, this video really helped me get a visual. The book was slow and dry.

[SNDVeteran]

Learned this in network defense essentials and this is a execellent video for briefly explaining cyptography.

[kiranvadlamudi]

Started understanding more and more. These concepts are most important. Thanks for the video.

[REZAZIMohamedabdessamed]

This is really a good and clean approach of clarifying the term!

[when_life_gives_you_limes]

A very concise talk about PKI. Awesome!

[dancalmusic]

Jeff Crume, as usual an awesome teacher

[waliedahmed]

This is the best channel for explaining cybersecurity concepts.

[hnmrykp]

Great explanation to clear any confusion with this topic, much appreciated!

[StopWhining]

Very clear explanation; thanks for somewhat demystifying PKI.

[s.gardner]

This is some very clear and really exciting stuff. Haven't seen many people break this down in such a way making it so easy to understand. Good stuff guys!

[sitrakaforler]

More pedagogy than during my bachelor 😭
Keep it
