  • sled

    the champagne of beta embedded databases

    Project mention: Are there any embedded databases that have multiple-process support? | | 2023-01-10

    I'm not sure what you need. Are these of any use?

  • foundry

    Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

    Project mention: Build Your First Subnet | | 2023-01-27

    After you feel comfortable with this deployment flow, try deploying smart contracts on your chain with Remix, Hardhat, or Foundry. You can also experiment with customizing your Subnet by addingprecompiles or adjusting the airdrop.

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Platform where developers build real-time applications for analytics, IoT and cloud-native services. Easy to start, it is available in the cloud or on-premises.


    🐇 Fuzzing Rust code with American Fuzzy Lop

    Project mention: [Gitoxide in July]: `git-config` release candidate and `cargo` slow-start | | 2022-08-22

    I had the same experience with pomsky, setting up cargo fuzz is simple and well worth it! I also use, which was able to find a stack exhaustion bug that cargo fuzz didn't find.

  • LibAFL

    Advanced Fuzzing Library - Slot your Fuzzer together in Rust! Scales across cores and machines. For Windows, Android, MacOS, Linux, no_std, ...

    Project mention: LibAFL, the Advanced Fuzzing Library reached 0.8.0 - develop fuzzers in Rust | | 2022-07-20
  • cargo-fuzz

    Command line helpers for fuzzing

  • fuzzcheck-rs

    Modular, structure-aware, and feedback-driven fuzzing engine for Rust functions

    Project mention: Fuzzcheck (a structure-aware Rust fuzzer) | | 2022-02-26

    Fuzzcheck is a structure-aware fuzzer for rust. "Fuzzing" means feeding large amounts of data into a program and checking for crashes (Fuzzcheck also checks to make sure that all the properties your program should uphold – e.g. a sorting algorithm applied to a list of n items should always return a list of n items – are upheld). Fuzzcheck is an "evolutionary" fuzzer – this means that it generates a set of random inputs, sees what percentage of the program is executed for each input, and keeps inputs which have high levels of percentage of program executed. It then "mutates" these inputs – whereas fuzzers such as AFL/Hongfuzz/etc mutate raw bytes in place (e.g. they swap bytes at different positions, or insert a random byte at a given position to generate inputs similar to the chosen "high coverage" inputs), Fuzzcheck works directly on the Rust types (so it might swap the order of two items in a vec, or randomly insert a new item). It's a really powerful tool for finding lots of bugs.

  • siderophile

    Find the ideal fuzz targets in a Rust codebase

    Project mention: Rust code quality and vulnerability scan tool | | 2022-05-01

    I'll go ahead and plug siderophile -- you can use it to find all the uses of unsafe in your codebase, and prioritize them for fuzzing, human review, etc.

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

    A symbolic-model-guided fuzzer for TLS

    Project mention: Keeping the Wolves Out of WolfSSL | | 2023-01-12

    LibAFL served as a basis for this project.
