  • GitHub repo qtum

    Qtum Core Wallet

    Project mention: Check the new QRC20 commands built to Qtum | reddit.com/r/Qtum | 2021-09-05
  • GitHub repo cryptominisat

    An advanced SAT solver

    Project mention: kotlin-satlib: SAT solver wrappers for Kotlin | reddit.com/r/Kotlin | 2021-07-13

    Alongside with the SAT solver interface and its extensions, `kotlin-satlib` provides wrappers for native SAT solvers (these days, most of them are written in C/C++) implemented using JNI technology. Currently, the solvers included are: MiniSat, Glucose, Cadical and CryptoMiniSat. Sadly, `kotlin-satlib` won't work out-of-the-box, you have to provide it with some external SAT solver, either in the form of a library or a binary. Luckily, there are build instructions for each of the supported SAT solver, both for Linux and Windows. Checkout the README!

  • GitHub repo cryptofuzz

    Fuzzing cryptographic libraries. Magic bug printer go brrrr.

    Project mention: You Shouldn't Roll Your Own Crypto: An Empirical Study | news.ycombinator.com | 2021-07-25

    I understand that they base their research on CVE data because it offers normalized quantifiers of severity and scope, but in my experience vendors by and large don't bother with CVE's for API bugs even when the affected primitive is clearly malfunctioning (memory or correctness issues).

    I've been deeply fuzzing cryptographic libraries for a few years and found about 130 bugs [1]. The vast majority of these did not receive a CVE. Now some of these are merely theoretical, others will only manifest under particular circumstances like specific calling sequences, others were caught in the development phase before landing in stable releases, but a number of them are outright vulnerabilities. The usefulness of CVE incidence is questionable when it is so strongly influenced by the vendor's propensity for reporting these.
