Two modern methods of encryption are the Public Key (Asymmetric) and the Private Key (Symmetric) methods. The encrypted information is unreadable to anyone who does not have access to a special key used to decrypt the information so that it’s readable. Modern data encryption makes use of an algorithm known as a cipher to convert information into what appears to be random characters or symbols.
#Encrypted data meaning code#
While the encryption used in today’s secure messaging apps is much more complicated and secure than any secret code you used in grade school, the theory is still the same at its basic roots. Perhaps you used an “encryption” code similar to “A = 18, B = 23, C = 5” and so on. You might have used a basic form of encryption to send “secret” messages to your school chums when you were in grade school. The concept of encryption is millennia old, as Roman Emperor Julius Caesar reportedly used a simple form of encryption to send messages to his generals. Many encrypted messaging apps also offer end-to-end encryption for phone calls made using the apps, as well as for files that are sent using the apps.Įncryption is the process of encoding information to prevent anyone other than its intended recipient from viewing it. Encrypted messaging prevents anyone from monitoring your text conversations. What Is Encrypted Messaging, and How Does It Work?Įncrypted messaging (also known as secure messaging) provides end-to-end encryption for user-to-user text messaging. In this article, I’ll explain how encrypted messaging works, which devices this type of messaging are available on, and which apps provide the best encrypted messaging protection and experience. Not all encrypted messaging apps are created equal. If you’re using standard, unencrypted SMS texting, such as what your wireless carrier offers, you’re leaving yourself open to monitoring by your carrier and your government, as well as hackers and criminals.
I n today’s world of revelations that the National Security Agency (NSA) is spying on citizens in the United States, and the United Kingdom requires Internet Service Providers to record their customer’s online activities, secure, encrypted messaging is more important than ever.
