csprng

PHP 5.x support for random_bytes() and random_int()

Collection of miscellaneous portable C snippets.

A collection of single-file C libraries. (generic containers, random number generation, argument parsing and other functionalities)

A fast userspace CSPRNG

10x faster than crypto/rand

A crypto-secure random bytes generator for react native

🔣 ISAAC is a fast, seedable, cryptographically secure pseudo-random number generator (CSPRNG) and synchronous stream cipher.

A port of the Google Randen fast backtracking-resistant random generator to the C language.

✨ A purely functional random number generator

Generate a cryptographically secure pseudo random token of digits with n-length

Kotlin multi-platform cryptographic utility library.

A fast AES-PRF based secure random-number generator

ADAM is an actively developed CSPRNG inspired by ISAAC64

建議開發者知道的密碼學知識

CLI tool that generates and outputs secure random string of choice

Real-time client-side password strength and entropy analyzer. Calculates Shannon entropy, detects repeated patterns and keyboard walks, and models brute-force cracking speeds across modern GPU clusters, hardened slow hashes, and throttled web logins. Includes a secure CSPRNG generator. 100% in-browser with zero dependencies.

Notes I took during DayCamp4Developers, June 2017.

Browser-based password checker and generator: CSPRNG generation, EFF passphrases, zxcvbn-ts estimates and a k-anonymity breach check.

A Quantum computer based CSPRNG, written in python, as a PoC for using QCs in services.

Post-quantum WASM cryptography. Authenticated encryption, signatures with key agreement, transparency logs, and ratcheting built on constant-time bitsliced ciphers (Serpent, XChaCha20, AES), post-quantum schemes (ML-KEM, ML-DSA, SLH-DSA), BLAKE3 and SHA-family hashing, and the Fortuna CSPRNG. Zero dependencies, tree-shakeable, side-effect-free.
