Politicians have turned their sights on encryption once more following terrorist outrages in Paris and San Bernardino, California.
A country that once welcomed encryption, France is now considering outlawing it in the wake of the massacre in its capital. In the United States, politicians and law enforcement have made similar demands, as has British Prime Minister David Cameron.
Encryption creates trust. It is the underpinning of the Internet, ensuring the privacy of mail, commerce, and transactions of all kinds. End-to-end encryption, where data such as texts, emails, or other messages are encrypted in transit and in storage, and where no third party other than those communicating have the keys to decrypt it, has come under particular criticism.
