Encryption Part I: Introduction to Encryption 4

The 4th video in this series, covering random numbers and how to generate them.

It's fascinating the fields of encryption and compression.

You and Veritasium both did a video on this aspect of encryption on the same day! Both are excellent quality!  i am quite likely to share your encryption videos with folks to get their circuits checked on this subject!

[ph.schmitt]

Absolutely captivating. Thank you so much for this riveting introduction to cryptography. The real life examples complete the lessons and are very interesting. More of that! I feel truly enlightened, as I finally grasp at concepts which I did not dare to research, as I presumed they would be too complex to learn. What I didn't fully understand was Periodicity and the example with the simple PRNG using 4 as a seed. I did not understand why the output started to loop.

in the first sequence you show in the Periodicity part (7:00), if every number is the seed for the next one, how come before the first "4" there's "1", but before every other "4" there's a "9"?

I have developed a totally different method for encryption. Is there somewhere I can send it to be tested to see if anyone can break it? It is unlike anything in these videos and I believe it can not be broken unless you understand the method of encryption.

I would appreciate any help anyone can give me. I would like to eventually sell my encryption method in the end if it can hold up.

*truly random numbers must be distributed uniformly (NOT distributed normally)

[StahlFirearmsNo]

I know a way of encryption that is so random that it almost isn't encryption
