![]() ![]() In the process, it also guarantees that no unauthorized user can read the data.įor example, services like Gmail, Google, or Microsoft give providers copies of the decryption keys, allowing them access to users’ content on its servers, enabling the providers to read users’ email and files. This level of security makes end-to-end encryption an extremely valuable and essential part of doing business in the 21st century.Įnd-to-end encryption is essential because it offers users and receivers the necessary security for their message and data from the moment the user sends the information until the instant the recipient gets it. Why End-To-End Encryption Is Important and What It Protects AgainstĮnd-to-end encryption is the virtual equivalent of locking your data in an impregnable safe and sending it to the only person who knows the combination. ![]() ![]() Then, if Don wants to reply to Ron, he repeats the process, encrypting the message to Ron using Ron's public key. Then, when Don gets the message, he uses his private key that’s already on his device to decrypt Ron’s message. Ron wants to send Don an encrypted message, so he uses Don’s public key to encrypt the message. The public keys are stored on the server, but each person’s private keys are stored on their devices. This end-to-end encrypted system gives each person a public-private key pair. Ron and Don have both created accounts on their corporation’s system. Let's look at an example and how this all comes together. However, private keys are only known by the respective owner at each end (the senders and receivers) and are used to decrypt or unlock the information. The information, however, can only get decrypted with the correct private key, also called the decryption key. Users encrypt their transmission using the public key and send it to the user who also has that public key. Everyone in the network (e.g., a corporation's email system) can access the public key. Public keys are widely distributed and used to encrypt or lock the message. This method, also called asymmetric cryptography, uses separate cryptographic keys to secure and decrypt the data. How Does End-To-End Encryption Work?Įnd-to-end encryption’s fundamental element is the creation of a public-private pair of keys. To sum it up, end-to-end encryption is an encryption system that stands out from other encryption systems because only the sender and the receiver, otherwise known as the endpoints, can decrypt and read the information. You can read more in-depth information about PGP here. ![]() When parties use end-to-end encryption to send an email or data to someone, no one sees your message's content, including the government, hackers, or even the Internet Service Provider (ISP), or applications provider.įor example, several end-to-end data encryption methods exist, such as PGP (Pretty Good Privacy). Instead, data gets encrypted at the device level, meaning files and messages are encrypted before sending and get decrypted only after they arrive at their destination. Other than the sender and the receiver, no one can access information in an end-to-end encryption system. End-to-end encryption, or E2EE for short, is a secure communication method that encrypts data transferred from one end device or system to another while preventing third parties from accessing the data. ![]()
