In our increasingly world of technology, it is important to know how to protect our virtual identities. Every time we log into our email, make an online purchase, or even just surf the web, our personal information has the potential to be stolen by cyber criminals. This is where encryption comes in. Encryption is a method of coding or scrambling data so that only authorized parties can understand it.
Picture sending a letter through the mail, but before you seal the envelope, you use a special decoder ring to change all the words into a secret language. Only the person with the matching decoder ring (or key) can understand your message. This is similar to how encryption works in the digital world – it helps to keep our personal information safe from people who might want to steal it.
In today’s digital world, there are two types of encryption – symmetric and asymmetric. Symmetric encryption is like having one key that both you and the receiver have to lock and unlock a message or data. If the key gets lost or stolen, then anyone can read the information. Asymmetric encryption, on the other hand, uses two keys – one to lock or encrypt the data and another one to unlock or decrypt it. This type is often considered safer because even if someone manages to steal one of the keys, they would still need the other one to actually read the information.
Secure sockets connections, you might have seen ‘https:’ at the start of a website, are often used when you are shopping online or accessing your bank account. HTTPS uses asymmetric encryption to protect your data as it travels from your computer to the server of the website you’re using. This means that nobody can snoop in on your conversation or transaction, keeping your personal and financial information safe.
Encryption is an essential tool in our digital world for keeping our information safe. Without it, our emails could be read by anyone, and our sensitive personal information could be easily stolen. In essence, encryption acts as a digital lock for our data, ensuring that it only gets into the right hands.
So while it might seem a bit complicated, understanding the basics of encryption and how it keeps your data safe is important, even for the average internet user. So the next time you see ‘https:’ at the start of a website, you can appreciate the technology that helps keep your information secure.
