Top 23 C++ Cryptography Projects

  • Bitcoin

    Bitcoin Core integration/staging tree

    Project mention: Generating and Working With ScriptPubKeys in Bitcoin Transactions | dev.to | 2024-02-27

    As mentioned previously, ScriptPubKeys are scripts that embody the locking conditions of bitcoins in a Bitcoin transaction. They are a crucial element of a Bitcoin transaction that specifies the requirements that must be met before an unspent transaction output (UTXO) is used. The ScriptPubKey, combined with the Amount, creates an output of a Bitcoin transaction. Like every other script, ScriptPubKeys are made up of operators and data. During the encoding of a transaction, both data and the operands are represented in hexadecimal format. You can find the hex representation for all operands used in Bitcoin Scripts here.

  • monero

    fixDisallowIncomingV1: Fixes an issue that occurs with authorized trustlines and the “lsfDisallowIncomingTrustline” flag.

  • fully-homomorphic-encryption

    An FHE compiler for C++

    Project mention: What are the current hot topics in type theory and static analysis? | /r/ProgrammingLanguages | 2023-05-08

    Secure computing. This includes Fully Homomorphic Encryption AKA FHE, of which there is a language/compiler which just got released and Google's older FHE compiler. FHE is probably more "compiler" than "type system", e.g. Google's compiler works on C++. Also Security Type Systems which include Oblivious data structures and Oblivious ADTs.

  • SEAL

    Microsoft SEAL is an easy-to-use and powerful homomorphic encryption library. (by microsoft)

    Project mention: On Intel SGX, is it possible to set an executable running such that you, the operator, cannot decrypt its state? | /r/crypto | 2023-12-07
  • HElib

    HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • i2pd

    🛡 I2P: End-to-End encrypted and anonymous Internet

    Project mention: I want to help the network, but need assistance | /r/i2p | 2023-11-05

    I'm running a tor bridge on my home proxmox box, and I'm interested in running an i2p node as well but I have no experience with this. From what I was able to gather the easiest way is to install the i2pd .deb (https://github.com/PurpleI2P/i2pd/releases).

  • Botan

    Cryptography Toolkit

    Project mention: Ask HN: What are some of the most elegant codebases in your favorite language? | news.ycombinator.com | 2023-06-17
  • cryfs

    Cryptographic filesystem for the cloud

    Project mention: Syncthing: Untrusted Device Encryption | news.ycombinator.com | 2023-12-07

    I know that cryfs[1] is resilient to at least the first of these, and possibly the second as well. I don't know if cryfs allows to modify the base directory while the filesystem is online, if it does then it might already be a better solution for syncthing, if you only care about Linux.

    On the flip side syncthing could incorporate cryfs's base directory format instead of their home-grown one.

  • fhe-toolkit-linux

    IBM Fully Homomorphic Encryption Toolkit For Linux. This toolkit is a Linux based Docker container that demonstrates computing on encrypted data without decrypting it! The toolkit ships with two demos including a fully encrypted Machine Learning inference with a Neural Network and a Privacy-Preserving key-value search.

  • risc0

    RISC Zero is a zero-knowledge verifiable general computing platform based on zk-STARKs and the RISC-V microarchitecture.

    Project mention: The Cairo Programming Language | news.ycombinator.com | 2023-05-03

    You can actually write zkps in pure Rust, but there's not currently any blockchain integration: https://github.com/risc0/risc0

  • qtum

    Qtum Core Wallet

    Project mention: How to use QTUM? | /r/Qtum | 2023-12-07

    Download the official Qtum wallet from qtum.org and you can stake (or delegate staking) directly through your wallet

  • concrete

    Concrete: TFHE Compiler that converts python programs into FHE equivalent

    Project mention: Concrete: Converts Python programs into homomorphic encryption equivalent | news.ycombinator.com | 2024-03-09
  • WaykiChain

    Public Blockchain as a Decentralized Finance Infrastructure Service Platform

  • steganography

    Simple C++ Image Steganography tool to encrypt and hide files insde images using Least-Significant-Bit encoding.

  • cryptominisat

    An advanced SAT solver

    Project mention: The Silent (R)evolution of SAT | news.ycombinator.com | 2023-05-26

    ManySAT: http://www.cril.univ-artois.fr/~jabbour/manysat.htm

    It shares short conflict clauses between parallel solvers and achieves superlinear speedup in some cases, e.g., 4 parallel solvers solve faster than one forth of the single solver soolution time.

    Short conflict clauses are rare so there is little communication between solvers required.

    CryptoMiniSAT: https://github.com/msoos/cryptominisat

    Author's goal to have solver that is good in computing range from single CPU up to cluster. Judging from CryptoMiniSAT successes, he has mostly reached the goal.
