Among the many tales of innovation and impact to come from Galois over the years, the origin story of Cryptol and SAW is perhaps the most closely tied with that of the company itself. Today, these open-source verification tools have been used in national security, fintech, and cloud computing applications to keep citizens, systems, and […]
Galois’s mission is to help make the critical systems that the world relies on more secure and trustworthy. Over the years, we’ve put our team’s deep expertise in software correctness, cryptography, digital engineering, and machine learning to work, providing formal assurance for complex systems in high stakes contexts for both government and commercial clients. From […]
We are pleased to announce the release of Cryptol 2.13.0. Cryptol is a language for writing and specifying cryptographic algorithms. This release brings a variety of improvements, including: The sortBy function is now implemented using merge sort instead of insertion sort. This improves both asymptotic and observed performance on sorting tasks. “Type mismatch” errors now […]
Cryptography continues to rapidly transform our world. It seems like every day there’s a new story about fully homomorphic encryption, blockchains, and how these technologies secure billions and even trillions of dollars in assets. We’ve talked about cryptographic algorithms and twice about cryptographic assurance. People who work with these concepts every day have been the […]
Field arithmetic code is important and has edge cases lurking everywhere. Cryptol is a tool that can guarantee you’ve got the edge cases right! In this post, we continue reproducing an NCC Group Post about programming in z3. In our last post, we checked the implementation of part of the QUIC protocol. Now we’ll explore […]
We’ve been working to improve usability for SAW, our tool for verification of C and Java programs. The primary way that users interact with SAW is its specification and scripting language. In order to make SAW as accessible as possible, Python can now be used as that language for SAW! We’ve built an example to […]
At Galois, we’ve run into NCC’s Cryptography Group numerous times, because Galois’ services and NCC’s complement each other extremely well. For example in the ‘blst’ cryptographic library project from Supranational, Ethereum Foundation, and Protocol Labs, NCC provided a public audit and report, while we at Galois have verified much of the core library. When I […]
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.
