Encryption basics
(bright music) - [Instructor] Welcome to this lesson on encryption basics. In this particular lesson, we are going to look at what encryption is, what different kinds of encryption algorithms exist, what does it mean to have symmetric encryption versus asymmetric encryption, et cetera. So let's start with the basics first. Encryption is used to transform plain text data into cipher text. What does cipher text mean? Or cipher text is also referred to as encrypted text. Basically what it means, it's a series of randomized letters and numbers which humans cannot make any sense of. Plain text, you can make sense. Once it's encrypted, cipher text, you cannot make sense of that just by looking at it. Decryption, which is the reverse process, is used to transform the cipher text into plain text. So plain text, you take and then you encrypt it into cipher text. That's encryption, and the reverse process is decryption. Now…
