EverParse
March 2021
EverParse is a framework for automatically generating fully verified secure parsers from data format specifications described in domain-specific languages. It consists of a verified F* combinator library, and untrusted frontends compiling from data format specifications to verified parsing combinators.
HACL*
October 2019
A High-Assurance Cryptographic Library (HACL*), a formally verified cryptographic library written in F*. This repository contains verified code for a library of modern cryptographic algorithms, including Curve25519, Ed25519, AES-GCM, Chacha20, Poly1305, SHA-2, SHA-3, HMAC, and HKDF.
Vale
June 2019
Vale (Verified Assembly Language for Everest) is a tool for constructing formally verified high-performance assembly language code, with an emphasis on cryptographic code. It uses existing verification frameworks, such as Dafny and F*, for formal verification. It supports multiple architectures,…
EverCrypt
June 2019
EverCrypt is a high-performance, cross-platform, formally verified modern cryptographic provider distributed as a combined C/ASM library. EverCrypt packages cryptographic implementations from the HACL* and ValeCrypt projects, and automatically picks the fastest one available, depending on processor support and the target…
miTLS
November 2018
miTLS is a verified reference implementation of the TLS protocol. Our code fully supports its wire formats, ciphersuites, sessions and connections, re-handshakes and resumptions, alerts and errors, and data fragmentation, as prescribed in the RFCs; it interoperates with mainstream web…
Z3 automated theorem prover
May 2018
Z3 is a theorem prover from Microsoft Research. It is licensed under the MIT license. Z3 can be built using Visual Studio, a Makefile or using CMake. It provides bindings for several programming languages including .NET, C, C++, Java, OCaml,…
KReMLin
May 2018
KreMLin is a tool that extracts an F* program to readable C code. If the F* program verifies against a low-level memory model that talks about the stack and the heap; if it is first-order; if it obeys certain restrictions…
