How does end-to-end encryption work?

- End-to-end encryption ensures that nobody  not even the server that connects you with others  can access your communications.

The communications in question could be anything from plain text and emails to files and video calls. 

-Data is encrypted in applications like Whatsapp, Signal, or Google Duo (supposedly) so that only senders and intended recipients can decrypt them. In end-to-end encryption schemes, you might kick that process off with something called a key exchange.

What are the advantages and disadvantages of end-to-end encryption?

To start with, End-to-end encryption is the practice of encrypting data and information as it passes from device to device. End-to-end encryption (E2EE) is a security measure that is designed to protect the privacy and confidentiality of communications by making them unreadable to anyone who is not the intended recipient. 

Advantage of  End-to-end Encryption (E2EE) 

1.Enhanced privacy

E2EE provides a high level of privacy and confidentiality for communications, protecting them from interception or surveillance by third parties, including hackers, governments, and service providers.

2.Security

E2EE provides a high level of security, as it ensures that only the intended recipients of a message can read its contents, preventing interception or tampering by malicious actors.

3.Trustworthiness

E2EE can increase the trustworthiness of online services and platforms, as users can be confident that their communications are protected from unauthorized access.

Disadvantages of end-to-end encryption

1.User experience

E2EE can make the user experience more complex, as users may need to take additional steps to verify the identity of the recipients and ensure that their messages are encrypted.

2.Risks of misuse

E2EE can be used by criminals and other malicious actors to evade detection and carry out illegal activities, such as terrorism and child exploitation, making it difficult for law enforcement to investigate and prevent these activities.

3.Limited data analysis

End-to-end encryption makes it difficult for companies to analyze user data for advertising or research purposes.

4.Compliance issues

End-to-end encryption may be in conflict with data retention laws or regulations in some countries.

5.Inability to recover lost data

With end-to-end encryption, data recovery is nearly impossible if the user loses the encryption key or password.
