A funny picture or a sweet message to tell her you love her. We transfer and store information across the internet all day long. Sometimes it’s innocent. Other times it’s information you want to keep to yourself.
That’s were encryption comes in! But what is encryption?
The principles of encryption aren’t new. Julius Caesar used a simple form of encryption to protect messages of military significance. Each letter in his plain text was replaced by a character three positions down the alphabet. He wrote a cipher text, unreadable for the enemy.
In modern day encryption, your plain data is altered with complex algorithms. Only people with the right key can decrypt the data and open its original form. As the length of the key increases, the number of possibilities increases exponentially, making your data more secure against a “brute force” attack. With this, a hacker tries as many different passwords as possible until he finds the right one.
Whether you surf on the internet, withdraw money, or send a message. Just like Caesar’s case, encryption keeps your personal and valuable data safe!
