Overview We have added support for semi-automated proof assistance and repair to Crux, Galois’s symbolic testing tool for C/C++ and Rust. These new capabilities build on support for logical abduction provided by the cvc5 SMT solver that suggests possible facts for failed proof goals, that, when assumed, make the proof goals provable. This feature can […]
We are pleased to announce the release of Crux 0.6. Crux is a tool for verifying programs containing inline specifications. Crux works with both C/C++ code (via Crux-LLVM) and Rust code (via Crux-MIR). This release brings a variety of improvements, including: Crux-LLVM now has improved support for LLVM debug metadata when the debug-intrinsics option is […]
This year Galois participated in the annual Competition on Software Verification (SV-COMP) for the first time with our verification tool, Crux. Preparing Crux to be in competition shape has been a project several years in the making, and we are very pleased to have reached this milestone. In this post, we will take a closer […]
A while back, we announced that we were open-sourcing Crux, a software verification tool. I’d like to work through a slightly more involved example in this post than those presented in the original announcement. In particular, I’d like to give an example of how one might apply Crux to verify functional properties of a system […]
UC-Crux is an open-source command-line tool and Haskell library for performing under-constrained symbolic execution on LLVM code for the sake of exposing bugs or verifying the absence of certain types of undefined behavior. It requires only LLVM bitcode as input. It is built on Galois’s Crucible library for symbolic execution. Under-constrained symbolic execution (developed by […]
Many of the verification and static analysis tools we build at Galois are based on the same technology: a symbolic execution engine for a language called Crucible. There are a lot of advantages to doing this. It’s what makes it possible for SAW to reason about C, C++, Rust, and x86 assembly, all through the […]
The standard development tools for the Rust language provide a convenient mechanism for embedding tests within your code that can then be automatically run using the `cargo test` command. This video shows how to migrate from testing to verification of Rust programs by converting a standard Rust test to use Galois’ Crux tool. Crux can […]
We are happy to announce the first formal release of Crux, a new open-source verification tool from Galois. This new tool aims to improve software assurance using symbolic testing, a technique that allows for smooth migration from testing to verification. Crux builds on the same infrastructure as our Software Analysis Workbench (SAW), but with a […]
We take pride in personally connecting with all interested partners, collaborators and potential clients. Please email us with a brief description of how you would like to be connected with Galois and we will do our best to respond within one business day.
