I have a lot of respect for ex-Microsoft Chief Software Architect Ray Ozzie, but when I saw that he'd taken to promoting a Clipper-Chip-style key escrow system, I was disheartened -- I'm a pretty keen observer of these proposals and have spent a lot of time having their problems explained to me by some of the world's leading cryptographers, and this one seemed like it had the same problems as all of those dead letters.

In a paper published by the International Association for Cryptologic Research, a group of Harvard and MIT cryptographers demonstrate that even if the government were to backdoor encryption and lock up anyone who used non-backdoored systems, people could still hide undetectable, secure, private messages within the messages sent over the compromised systems.

Cloudflare, a company with a history of resisting surveillance and censorship orders (albeit imperfectly and sometimes with undesirable consequences) has announced a new DNS service, hosted at the easy-to-remember address of 1.1.1.1, which accepts connections under the still-novel DNS-over-HTTPS protocol, and which has privacy designed in, with all logs written only to RAM (never to disk) and flushed every 24 hours.

The Electronic Frontier Foundation is running an excellent series on the potential and pitfalls of secure messaging app -- this is very timely given the ramping up of state surveillance and identity theft, not to mention anyone looking to #DeleteFacebook and transition away from Facebook Messenger.

Since 2016, when an FBI agent first used a dead suspect's finger to unlock his phone, police forces across the USA have made a routine practice of unlocking phones using suspects and victims' dead fingers, saving big on buying cyberwar tools like Cellebrite's $1500-$3000 unlocker, or Grayshift's $30k/year Graykey.

The epidemic of cryptojacking malware isn't merely an outgrowth of the incentive created by the cryptocurrency bubble -- that's just the motive, and the all-important the means and opportunity were provided by the same leaked NSA superweapon that powered last year's Wannacry ransomware epidemic.

The creation of "public ledgers" -- like blockchain, popularized by Bitcoin -- requires "consensus algorithms" that allow mutually untrusted, uncoordinated parties to agree on a world-readable, distributed list of things (domain names, transactions, title deeds, etc), something that cryptography makes possible in a variety of ways.

Working cryptography's pretty amazing: because of its fundamental theoretical soundness, we can trust it to secure the firmware updates to our pacemakers; the conversations we have with our loved ones, lawyers and business colleagues; the financial transactions the world depends on; and the integrity of all sorts of data, communications and transactions.
