Encrypt Sign Document Android

your Android is like a basket full of personal or corporate information that you wouldn't want to hand over to just any stranger that's why you take steps to secure your Android device and the data that it holds one great way to secure the data on your Android phone or tablet is through encryption hello I'm mark welcome to android authority in this episode I'm going to talk about encrypting data on your Android device I'll talk a bit about encryption as well as how to encrypt your Android phone or tablet encryption is the process of scrambling information thereby making the data no longer recognizable or understandable by unauthorized parties the process can be reversed it's called decryption and one will need a decryption key through decryption the Scramble data can be made comprehensible again because scrambled data is practically useless to anyone who doesn't have a decryption key encryption is actually a strong way to keep your data secure I'll use a simple illustration to show how encryption works let's say you have the word Android as text data on your phone and you want no-one to be able to read it so you decide to encrypt it for purposes of simplicity let's use a very simple substitution key to scramble the text let's substitute a with C B with D C with E and so on so when encoded or encrypted the word Android will become this it doesn't look like a word a it has become just a meaningless string of letters except for those who know that C stands for a P stands for n and so on a similar thing happens to your data when you encrypt it although in a more complex and sophisticated way than just substituting a with C as you can see encrypting your device can further secure your data it won't prevent your Android from being stolen but it can prevent a thief from using your encrypted data unless a thief is smart enough to know how to decrypt the data for most people setting a pin or password lock usually suffice us for keeping prying eyes away for those who need tighter security there's encryption if you're considering encryption for your Android phone or tablet take note of a few important things first your could show some lag after encryption the process uses device resources slow devices with limited resources could suffer a performance hit the lag will depend on factors such as processor RAM and disk read/write speed second initial full disk encryption can take a long time depending on the amount of data to encrypt don't ever interrupt your device while it is in the middle of encrypting you could permanently lose some or all of your data third once you encrypt your device there's no turning back encryption is irreversible the only way to return it to an unencrypted state is to reformat your device and lose all your encrypted data in the process...
