In an era where data privacy is a major concern, End-to-End Encryption (E2EE) has become a crucial technology to protect user communications from unauthorized access. At its core, E2EE relies on asymmetric encryption, which uses a pair of cryptographic keys—one public and one private—to ensure secure communication between parties. Because the Signal app has been in the news recently, this article explores how asymmetric encryption works in E2EE, how public and private keys function, and some of the most popular applications implementing this security measure.
