Tech Interview Prep First let's define encryption Core idea is to change a message, say a text file, using an algorithm Once encrypted you must know they formula to decrypt the message For example we can encrypt Kimavei as a number by converting K to 11, K is at 11th place in alphabet order, and so on. Now let's understand Symmetric vs Asymmetric Encryption Symmetric - One key This is the simplest kind of encryption that involves only one secret key to cipher and decipher information The sender and the recipient should know the secret key that is used to encrypt and decrypt Asymmetric - Two key Asymmetric encryption is public key cryptography A message that is encrypted using a public key can only be decrypted using a private key, a message encrypted using a private key can be decrypted using a public key. Security of the public key is not required because it is publicly available .... .... Thank you from Kimavi, Please visit us at Kimavi.Com for more Super Simple Educational videos
