    On cryptography, our whitepaper shares information on the general cryptography choices - login, authentication, keypairs, etc. It's quite similar to password managers or encrypted communication apps. In the actual product (code here, we use the library TweetNaCl ( which is designed to be fast, trustworthy, and performant

  • multi-party-ecdsa

    Rust implementation of {t,n}-threshold ECDSA (elliptic curve digital signature algorithm).

    Project mention: Answering questions about our new secure crypto app | | 2021-10-20

    Ha nice call!

    Unfortunately we have not completed a satisfactory security audit. We engaged with one company, but I don't think they were worth their salt. The problem is that the "good" companies are much more expensive, so it's a consideration of the value of the security audit. (If you know of a reputable company that would like to audit for free though...)

    The code is not yet open source, but we are primarily expanding on this open-source library.

  • signatory

    Differentiable computations of the signature and logsignature transforms, on both CPU and GPU. (ICLR 2021)

    Project mention: [R] Authors Claim to Have "Solved" MNIST and CIFAR | | 2022-04-19

    As it happens, I know quite a lot about signatures. I spent half my PhD working on them. For example I am the author of the most popular library for computing signatures, which involved coming up with some new asymptotically optimal algorithms for computing them. So that's my credentials out the way.

  • webext-signed-pages

    A browser extension to verify the authenticity (PGP signature) of web pages

    Project mention: Truly safe? | | 2022-06-30

    There are also projects like signed web pages which can also help increasing the trust level to some degree. But that requires that you can download the source code and regenerate the verification hash locally - or have other trusted methods to verify the hash value hasn't been modified as well. The current concept is reasonably sane, but it requires too much from users currently to make it widely used.
