What is End-to-End Encryption?
End-to-end encryption (E2EE) applies encryption to messages and files so only the sender and the intended receipient(s) can read them. End-to-end encryption occurs at the device level. This means the messages and files are encrypted before they leave the computer or device and aren't decrypted until they reach their destination.
Data stored on servers cannot be accessed by hackers or unintended recipients because they do not have the private keys
to decrypt the data. The keys needed to decrypt the secure data are only stored on the sender's and recipient's devices.
How Does End-to-End Encryption Work?
Let's use an example to see how messages and files are protected throughout their journey.
In our encryption explanation
, we briefly mentioned public and private keys. This key combination is how secure message and file access is managed.
Why is End-to-End Encryption Important?
This enhanced level of encryption protects messages from sender to recipient as well as during storage. Because there is no point in sending and receiving where the data is in plaintext, the potential for hackers' access is practically eliminated.
As online meetings and learning have become the new way of doing everyday business, end-to-end encryption has become a key consideration. We'll dive into online meeting platforms and security in another topic.
We all know that data breaches have occurred, and the victims have not always been small companies. Even the most secure encryption methods and business practices cannot ensure 100% protection from hackers. However, the end-to-end encryption protection makes the hacker's job significantly more difficult.
When sharing confidential, sensitive, or personal data, end-to-end encryption is the essential standard.
Compare the example above with the plaintext to ciphertext example here
. It's easy to see the benefits of end-to-end encryption.
