The spiped secure pipe daemon
Spiped (pronounced "ess-pipe-dee") is a utility for creating symmetrically encrypted and authenticated pipes between socket addresses, so that one may connect to one address (e.g., a UNIX socket on localhost) and transparently have a connection established to another address (e.g., a UNIX socket on a different system). This is similar to 'ssh -L' functionality, but does not use SSH and requires a pre-shared symmetric key.

TweetNaCl.js
Port of TweetNaCl / NaCl to JavaScript for modern browsers and Node.js. Public domain.

The primary goal of this project is to produce a translation of TweetNaCl to JavaScript which is as close as possible to the original C implementation, plus a thin layer of idiomatic high-level API on top of it.

Introducing Cloudflare’s IPFS Gateway
What can you do with Cloudflare’s Gateway?

At the most basic level, you can access any of the billions of files stored on IPFS from your browser. But that’s not the only cool thing you can do. Using Cloudflare’s gateway, you can also build a website that’s hosted entirely on IPFS, but still available to your users at a custom domain name. Plus, we’ll issue any website connected to our gateway a free SSL certificate, ensuring that each website connected to Cloudflare's gateway is secure from snooping and manipulation.

The Road to QUIC
QUIC (Quick UDP Internet Connections) is a new encrypted-by-default Internet transport protocol, that provides a number of improvements designed to accelerate HTTP traffic as well as make it more secure, with the intended goal of eventually replacing TCP and TLS on the web. In this blog post we are going to outline some of the key features of QUIC and how they benefit the web, and also some of the challenges of supporting this radical new protocol.

Permanent Docker Images On IPFS
A little known feature of Docker is the ability to dump images into a tar file, and then load them back into the system. This can be accomplished with docker load, and docker save. This makes it very easy to use docker without any dependency on a registry.

mmproxy - Creative Linux routing to preserve client IP addresses in L7 proxies
mmproxy, a PROXY protocol gateway. mmproxy listens for remote connections coming from an application level load balancer, and spoofs the client IP address. From the application’s point of view, this spoofed connection, coming through mmproxy, is indistinguishable from a real one, connecting directly to the application.

So this became my ultimate research goal: a collaborative iPhone text editing demo that synced entirely over CloudKit. (And here’s a spoiler: it worked!)

How to Subvert Backdoored Encryption: Security Against Adversaries that Decrypt All Ciphertexts
Parties cannot simply encrypt ciphertexts of some other encryption scheme, because citizens caught trying to communicate outside the government’s knowledge (e.g. by encrypting strings which do not appear to be natural language plaintexts) will be arrested. The one guarantee we suppose is that the government mandates an encryption scheme which is semantically secure against outsiders: a perhaps reasonable supposition when a government might consider it advantageous to secure its people’s communication against foreign entities.
But then, what good is semantic security against an adversary that holds all the keys and has the power to decrypt?


We show that even in the pessimistic scenario described, citizens can communicate securely and undetectably.

Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder (see benchmarks below). It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set. Zstandard library is provided as open source software using a BSD license.
