the mailbox analogy of everyone knowin the address of the mailbox being the public key, and only the mailbox owner with the keys to his own mailbox as the private key, is a really really really well done analogy. probably the best one ive seen so far with relating public/private keys as a concept to everyday life and making it easier to understand.

@mjk012579 3 года назад

Very clear and straightforward. I’ve been beating myself over the head with this topic in my fundamentals class and this just made the differences make a whole lot more sense

@justArandomfellar 10 месяцев назад

@ender5023 7 месяцев назад

Same! This totally makes sense to me now!

@SannySinghs 6 лет назад

LoL 221b BakerStreet . I have been trying to understand Asymmetric encryption concept for nearly 3 hours. None of the clips i watch explained as clearly as you do about exchanging public key. Well done. Thank you so much

@simplyexplained 6 лет назад

You're the first one who noticed the address! Thanks for the kind words ;)

@JonathanCoffey1087 6 лет назад

Same here, this idea helped me a little. Since most of these videos keep mentioning TONS of keys, why not use a lock analogy? We generate a key pair, one public and one private. Think of the public key as the unique "lock" you've just made. You can give that lock to as many friends as you want. If you send me your lock, I can put anything in a box and put your lock on it. Once secured with your custom lock, I can no longer open or see the contents of that box without your key that's paired with that lock.

As an American I can honestly say 221 baker is literally the only address I know in that entire country.

@kairollmann 6 лет назад

And the next important thing to understand is: Asymmetric encryption algorithms take WAY longer than symmetric encryption algorithms. So people 1) use symmetric encryption to encrypt LARGE amounts of data / files, 2) encrypt the symmetric key with asymmetric encryption and 3) send that (asymmetrically) encrypted symmetric key together with the (symmetrically) encrypted file.

@simplyexplained 6 лет назад

+Kai Rollmann jep, 100% true. Should've added that to the video.

@Markd315 5 лет назад

And after that, probably how RSA can also be used to sign and verify data integrity.

Man you explained it in so much simple manner. I don't even need to note it anywhere. It was like a story that's in my head. Thanks a lot sir.

@lakerfan4life308 Год назад

Excellent explanation on asymmetric encryption. I was uncertain on how could the encryption of locking/unlocking the data worked since the private key never crossed the wire. You introduced and delivered that difficult concept in an easy relatable manner. Thank you for that! Best video ever. I now feel more confident about asymmetric encryption.

@Nawdiral 6 лет назад

The key words here I was really looking for since a while are: "...algorithm will generate a public and private key that are mathematically linked to each othere. Public keys can be used to encrypt data and only the matching private key can be used to decrypt it.".

Excellent, this kind of analogies, depicts better the problem for being understood, as the coffer or something like it, than a plain explanation declaring rules and results, because is better mentally thought in mind...beyond and respecting the math matter that is another more complex and low lever discussion. i love this class of analogy when is well applied. thanks for the video

You should also mention that encryption works in the other way too. An encrypted message with a private key can be decrypted only by the paired public key and this insures that the sender (or whoever encrypted the message) is indeed trusted.
