  • The words encryption and decryption are quite familiar to us. You might have already come across these technical words in this video series, as well as in your daily life. What is encryption, and why is it needed? By the end of this video you will also understand the magic that prime numbers play in encryption and decryption technology.

  • @intron9

    Good video, however , it presented whatsapp as an encrypted communications app, and it's not a good idea to present it as such. Because they don't encrypt your chats if you upload them to G.drive , and also, photos or videos are never encrypted, Neither on normal chatting nor when backuping . That's why it says "messages" are encrypted (referring to only text msgs.) instead of showing "this chat or conversation is encrypted". I understand the backup part is optional, but the photo&video thing is a dangerous one, and they kinda of mislead the users. It's just good to know what they avoid telling.

    encryption ( and those keys and signature) is very hard to understand at first and confusing after that if you don't have to work with it daily. As a normal software developer who study these things since 2005 but have been struggling to forget how they work. This video would help new comers alot and even "pro" like me

    Great video. The only thing I don't get is at 5:30 how (26)^7 mod 33=104. This is impossible since 104 is greater than 33 and the mod operation only gives the remainder of any number when divided by 33. Shouldn't that be 5? How does one arrive at 104 by decryption? Appreciated

    1. What keeps someone from creating a list of factors for prime numbers and by that way making it quicker to figure out later?
    2. How is the first private key tranfered without giving anybody a change to steal it?

I guess that would be a bit too much for someone who's not in the matter. Anyway, great video, thanks for making it. Cheers.
