Encryption protects your data from cybercriminals. It is difficult for Hackers to access Encrypted Files. Encryption is nothing but converting plain text into cipher text.
Lets say you and your friend installed an Encryption Software. When you send a file to your friend, the Encryption Software Encrypts the file.
So, hackers cannot interfere or read the file. When the file reaches your friend, the Software will decrypt and show him the message.
The concept is not new, as it is used since olden days. During wars when sending updates, people used to encrypt the message in a coded language that only their men understand.
Therefore, even if the enemies got the letter, they couldn't understand what was written. The same concept is now called Encryption and is used in digital security.
An Encryption can be Decrypted by using a key. The key contains the codes to decrypt the Encrypted file.
There are two types of Encryption Algorithms:1. Symmetric Encryption:2. Asymmetric Encryption:
Symmetric Encryption is also called as Secret Key Encryption. In Symmetric Encryption, the same key is used to Encrypt and Decrypt the data. Therefore, the key is called as Secret Key.
Asymmetric Encryption is also called Public Key Encryption. Here we use two keys, which are Public Key and Private Key.
While sending a file we first lock (encrypt) it using a Public Key, then our Private Key. The receiver first unlocks (decrypts) it with his Private then, then Public Key.
Take a Letter as an Example. When sending to a person, we write his “To Address” and our “From Address”. You don’t have to worry about the Encryption Type while using Encryption Applications.
There are three Encryption Standards, that are AES, DES, and RSA. AES 256-Bit Encryption is the Best Standard. Encryption can be used for Personal & commercial use, but mostly used by government & business organizations.
