End-to-end encryption is both a powerful tool for privacy and a point of contention for security. On one hand, it offers salvation by securing communications against unauthorized access, ensuring that only intended recipients can read the messages. This privacy protection is crucial for activists, journalists, and anyone concerned about data safety. On the other hand, it's seen as a curse by law enforcement and governments, who argue that it provides a shield for criminal activities, making it harder to intercept illegal communications and protect public safety. This tension places end-to-end encryption at the center of a global debate on balancing individual privacy with societal security needs.
