This is why many websites use a protocol called HTTPS for encrypting data that's being sent between sites. Using Wi-Fi to connect to the Internet is convenient, but in terms of security, there’s always a trade-off as it won't be difficult for an intruder to intercept any connection, which could result in stolen user credentials and other sensitive data. Asymmetric encryption, or public key encryption uses what is called a key pair-a public key for encrypting a message, and a private key to decrypt it. Symmetric encryption, also known as secret key encryption, pertains to the sender and the recipient holding the same keys to encrypt and decrypt a message. There are two methods of encryption: symmetric and asymmetric encryption. Encryption is like sending secret messages between parties-if someone tries to pry without the proper keys, they won't be able to understand the message.

The concept isn't that different from children who come up with secret code words and other discreet ways to communicate, where only they can be able to understand the message. To encrypt a message, you need the right key, and you need the right key to decrypt it as well.It is the most effective way to hide communication via encoded information where the sender and the recipient hold the key to decipher data. Bruce Schneier, Cryptographer, Privacy and Security SpecialistĮncryption enhances the security of a message or file by scrambling the content. It should be enabled for everything by default, not a feature you only turn on when you’re doing something you consider worth protecting.” “Encryption works best if it is ubiquitous and automatic. This reason alone should serve as enough warning to those who haven’t considered protecting their communications via encryption. As many cases have proven, user and company data is increasingly being targeted by hackers and cybercriminals resulting in data breaches and targeted attacks.
It could, however, be visible to the telecom companies carrying your Internet packets, and your supposedly private and secure communications could be intercepted. Most people aren’t sure where that “somewhere” is, but that data should only be available to the service provider brokering your conversation. While we’re constantly looking or sharing information online, our data is fundamentally stored somewhere. Phone calls, emails, online purchases, social media, and general browsing are online activities we can no longer live without. But before you decide to put it off for other ways to protect your online communications, a few examples might convince you that encryption is one of the best methods to safeguard your privacy, even at times when you think it doesn’t count. As simple as it sounds, the math and extra steps can become onerous for beginners. Encryption is a system of mathematical algorithms that encodes user data so that only the intended recipient can read it. In reality, the idea of encryption isn't that complicated. When you hear the word encryption, the first thing that might come to mind is that it’s something only techies or geeks would understand, or use.
