Project Everest aims to build and deploy a verified HTTPS stack.

The HTTPS ecosystem (HTTPS and TLS protocols, X.509 public key infrastructure, crypto algorithms) is the foundation on which Internet security is built. Unfortunately, this ecosystem is extremely brittle, with headline-grabbing attacks such as FREAK and LogJam http://mitls.org/pages/attacks/ and emergency patches many times a year.

Project Everest proposes to definitively solve this problem by constructing a high-performance, standards-compliant, verified implementation of the full HTTPS ecosystem, from the HTTPS API down to and including cryptographic algorithms such as RSA and AES. At the TLS level, for instance, we will develop new implementations of existing protocol standards and formally prove, by reduction to cryptographic assumptions on their core algorithms, that our implementations provide a secure-channel abstraction between the communicating endpoints. Project Everest aims to be a drop-in replacement for the HTTPS library in mainstream web browsers, servers, and other popular tools.

What is Project Everest?

Project Everest is the combination of the following projects:

When combined together, the projects above will generate a C library that not only implements TLS 1.3 but is also proven secure.

Current status

We generate a C library, but the verification is not complete.

Our test client implements TLS 1.2 + TLS 1.3 Draft 18 and successfully connects to TLS 1.3 test servers. We have a prototype integration of miTLS within libcurl that one can use to git clone a remote repository.

Getting started with Project Everest

To make things easier for prospective users, the everest script performs high-level project management and revision tracking.

Prerequisite (Windows only). Open up a Cygwin64 terminal with a Cygwin git client. Our library is a native Windows DLL but we rely on Cygwin to provide the Unix tools that many of our projects rely on.

The first step checks out the high-level everest command.

git clone https://github.com/project-everest/everest
cd everest

This will ensure that your environment is sane. On Windows, this will fetch & install a proper version of OCaml and all packages for you.

./everest check

If you just want to read the sources, then the step below is sufficient; it will fetch blessed versions of all the projects, which are known to work together.

./everest pull

Building all the projects together should work at any time, and be achieved by running

./everest make

Please file bugs if something doesn’t work!
