What is end-to-end Encryption? How does it protect us?

Hey, Guys if you are a tech lover then one question definitely arises in your mind about End-to-End Encryption and you must have heard about it Especially when you use messaging or email services like Gmail or WhatsApp. Here you will also know how it makes and provide extra security layers in communication security. Today we will share complete information about What is End-to-End Encryption and how does it work?

What is end-to-end Encryption? How does it protect us

Nowadays ‘end-to-end encryption is very mandatory and is also used by many big tech companies. Once you may also have noticed that big tech giant companies such as Apple, Google, Meta, and Microsoft use the terms ‘end-to-end encryption’ in their services and apps, which is also known by the name of ‘E2EE’. Let us tell you that End-to-End Encryption is a system of making communication private, where only the sender and the receiver can see the messages. 

What is End-to-End Encryption?

Using some algorithms, Encryption is a process in which normal text characters are converted into an unreadable format for unauthorized parties. This algorithm use encryption keys to convert the media or regular text into an unreadable format so that only authorized sender and receiver users can see or read the message. End-to-end encryption also uses the same algorithm, but it is a step forward way of securing communication/messages from one end to another. The End-to-end algorithm is used for encryption to prevent third parties from accessing data by transferring data from one user’s device or another.

How does ‘E2EE’ Work?

The end-to-end encryption method starts with cryptography and The method of securing/protecting messages by converting them into an unreadable format is called ciphertext. Users can only view or decrypt the message in regular text with secret keys. it means that in E2E encryption only the receiver and sender can decrypt it. When messages are sent through E2E encryption then third parties also cannot access the encrypted data on the server. in this way, E2E encryption makes the data extremely secure. E2EE gives the standard security of communication. 

However, in end-to-end encryption, the data is also ENCRYPTED at the device level. It means that messages/files are encrypted before being sent from the devices. It is also considered the best security layer because It prevents unauthorized access to the data on the server they do not have private keys to decrypt/view the messages/data because secret keys are stored on sender and receiver devices.

The process in which security is enabled through the public-private key pair in end-to-end encryption is known as asymmetric cryptography. Asymmetric or public-key cryptography encrypts and decrypts data using two different cryptographic keys. The message can only be decrypted using the associated private key, also known as the decryption key. In end-to-end encryption, public and private cryptographic keys are created for each person joining the system.

How is E2EE different from other Encryption?

E2EE is slightly different from other Encryption because, in comparison to other Encryption systems, end-to-end encryption offers to encrypt or decrypt messages/files only at the endpoint, which is on the devices of the sender and receiver. The use of secret-key encryption provides a tough layer of encryption to the sender and recipient, but it uses only one key to encrypt the message. E2EE also ensures that the message is safe from others. However, E2EE messages cannot be decrypted on any service provider like Google, Apple, Microsoft, Meta, etc, and this is what makes end-to-end encryption differ from any other type of encryption method.

How does E2EE protect us?

Those Messages sent through E2EE can only be encrypted by the receiver, who has the key to read the message. It means that no one can read/view the message even on the server, as they do not have the private key to view the data. Only the sender and receiver can read the message. In this way end-to-end encrypted messages also prevent tampering. Although E2EE protects the actual message, the metadata such as date, time, etc. are not encrypted. E2EE only protects data between endpoints. This means that the endpoints themselves are vulnerable to attack.
