Constant-Time Character Encoding in PHP Projects
Constantine: modular, high-performance, zero-dependency cryptography stack for verifiable computation, proof systems and blockchain protocols.
Constant-complexity, deterministic, very fast memory allocator (heap) for hard real-time high-integrity embedded systems. Allocation takes ≈120 cycles @ RP2350 irrespective of heap usage. There is little activity because the project is finished and does not require further changes.
Pure-Rust traits and utilities for constant-time cryptographic implementations.
Templated type-safe hashmap implementation in C using open addressing and linear probing for collision resolution.
Lightweight library of data structures implemented in C++11, designed for constant time insertion, erasure, lookup, and fastest possible iteration.
A set of cryptographic primitives for building a multi-hop Proxy Re-encryption scheme, known as Transform Encryption.
Secure memory handling primitives for Rust — zeroization on drop, mlock-protected regions, constant-time comparison, and compile-time enforced memory safety boundaries
Fuzzer to automatically find side-channel (timing) vulnerabilities
TLSF: two-level segregated fit O(1) allocator
A simple value-sorted map type for Go that features constant-time reads and efficient iteration over records.
CRYPTOGAMS distribution repository
Keep smooth running averages without using arrays! Uses exponential moving averages and only 8-bytes no matter how many samples! No looping! No Arrays! Constant Compute Time! The sample size is adjustable at runtime. The average is available and accurate even before N samples have been received. Now with Callbacks!
Constant-time JavaScript functions
Shang-Mi cipher library. Constant-time implementation of SM2 and SM4.
Ultra high-performance secp256k1 ECC engine | Python, Node.js, Rust, Go, C#, Swift, Java bindings | CUDA, Metal, OpenCL GPU | ECDSA, Schnorr, FROST, MuSig2, BIP-352 | 15+ platforms
FIPS 203 ML-KEM (CRYSTALS-Kyber) for Rust. Pure-Rust, no_std, ACVP 180/180, KyberSlash-clean, SLSA L3 + cosign-signed releases. Published on crates.io as kyberlib and kyberlib-wasm.
Binsec/Rel is an extension of Binsec that implements relational symbolic execution for constant-time verification and secret-erasure at binary-level.
Initialize / Fill C++ array fast - O(1) time with only 1 extra bit of memory.
