Bideniable encryption provides that an "authoritarian" entity attempting to gain knowledge of a plaintext through coercion cannot distinguish between a real and fake plaintext if they are successful in compromising a key, randomness, or message.
The Snowden leaks six years ago (at the time of writing, Sep 2019) mark what, from my vantage point, looks like an acceleration of improvements to cryptography, and a half a decade of discoveries of fundamental flaws which broke the algorithms and hardware we rely on for privacy: Dual EC, Heartbleed, AES, Diffie-Hellman. This article looks at how things have changed since.
