How to encrypt and Decrypt text in Android? 

In many android applications, we hear that they have end-to-end encryption in their application. End-to-end encryption means they are encrypting the user data and then storing that data within the database. Encryption is basically coding a normal message into a specific code using a password which is also called a key. This password is used to encrypt as well as decrypt the data. 

In this video, we will be understanding how to encrypt and decrypt text data within our android application. We will be building a simple application in which we will be encrypting and decrypt our data with the help of a key. We will also understand how to use Cipher to encrypt and decrypt the data.
