Often we do not even think about our security, not only in everyday life but also in “online” life. Of course, there are many methods to protect yourself and one of them is end-to-end encryption in apps.
What is end-to-end encryption?
End-to-end encryption is a method of data transmission in which only users involved in communication have access to messages. Thus, the use of end-to-end encryption does not allow access to cryptographic keys by third parties. So to say end-to-end encryption protects the data being passed from one source to another.
How does end-to-end encryption work?
During the start of a communication session, two keys are generated on the device of each user: public and private. The last one is used to decrypt data, this key does not leave the local device.
The public key is transmitted to the user via an open communication channel (one or all, if there are several of them). Using the public key, the user can only encrypt the data, and only the owner of the corresponding private key can decrypt it. So everyone can intercept the public key. As a result of this, it will only be possible to transmit your encrypted data.
Having generated a pair of keys, the users exchange public keys, after which secure communication begins.
Text, video, audio, files, after encryption from the sender, get to the server, where they are stored until the recipient is able to receive the data. After that, depending on the strategy of the company that owns the server, the data is either destroyed or stored for some time.
Benefits of using end-to-end encryption
End-to-end encryption provides the highest level of protection for users who are very concerned about data privacy.
To manage your private data, you no longer have to rely on third-party services that can not sufficiently protect your data or scan your data and exchange the information received for advertising and research purposes without your knowledge.
While using the application with end-to-end encryption, the user has control over who is authorized to read the messages and receive files.
Of course, you should use a password to keep all your data from getting to strangers or to avoid any information leaks. But we want to warn you that if you lose your password, all data will be irremediably lost. There are several options to keep a secure backup of your password/key. For instance a sealed envelope in a safe, or a password vault on an external device (USB key, smartphone etс.). Keep your data safe and do not lose your password.
Summary
Nowadays end-to-end encryption is becoming increasingly used, especially in chat applications such as Telegram, WhatsApp, Signal, etc.
As public demand grows for the security of personal data and their communication online more and more companies are looking towards end-to-end encryption as the way to ensure that data leaks will never take place in their day-to-day operations.
