Privacy, power, and encryption: why end-to-end security matters | Computer Weekly

"Privacy is not a modern invention; it is part of the human condition of trust, dissent, and intimacy. Every society has developed ways to communicate beyond the reach of power: whispered conversations, sealed letters, coded language."

"We now live in what some have termed a 'golden age of surveillance,' in which governments, corporations, and adversaries possess the technical capability to monitor human interaction at unprecedented scale."

"End-to-end encryption (E2EE) preserves data confidentiality by masking data from unauthorized users and ensuring that only the intended recipients, with a decryption key, can access the data."

"E2EE transforms readable plaintext into unreadable ciphertext on the sender's device, keeps it encrypted during transmission, and decrypts it back into its original form only when it reaches its destination."

Privacy has always been integral to human interaction, with societies developing methods to communicate securely. Governments prioritize secrecy while seeking to uncover others' secrets. The current era is characterized by extensive surveillance capabilities, making the protection of sensitive information crucial. End-to-end encryption (E2EE) is vital for safeguarding private communications, ensuring that only intended recipients can access data. E2EE transforms readable data into encrypted formats, maintaining confidentiality during transmission and is increasingly adopted by individuals and organizations for data security.
