TopSecret.Cryptography.Argon2

Argon2i, Argon2d, and Argon2id (the Password Hashing Competition winner) for .NET, implemented as a System.Security.Cryptography.DeriveBytes. A maintained fork of Konscious.Security.Cryptography.Argon2.

using TopSecret.Cryptography;

byte[] password = ...;
using var argon2 = new Argon2id(password)
{
    DegreeOfParallelism = 8,   // lanes; tune to your hardware
    MemorySize = 65536,        // KiB (OWASP recommends >= 19 456 for interactive logins)
    Iterations = 3,            // OWASP recommends >= 3 for interactive logins
    Salt = salt,               // unique per secret, >= 8 bytes
};

byte[] hash = argon2.GetBytes(32);              // sync
byte[] hash2 = await argon2.GetBytesAsync(32);  // async — safe everywhere, including browser WASM

Targets netstandard2.0;net462;net6.0;net8.0;net10.0. DegreeOfParallelism = 1 also completes on single-threaded runtimes such as browser WASM — see the full README for the Browser/WebAssembly details, breaking changes between versions, and everything else that differs from the upstream Konscious project this forks.

TopSecret.ProtectedString

Cross-platform alternative to System.Security.SecureString. Stores sensitive characters encrypted in memory (AES-GCM with a per-process key) and exposes them only briefly through an Access(...) callback. Inspired by Evolveum's GuardedString.
TopSecret.Cryptography.ArgonBenchmarks

BenchmarkDotNet performance suite for TopSecret.Cryptography.Argon2 — measures Argon2i/Argon2d/Argon2id throughput across degrees of parallelism and target frameworks.
TopSecret.Cryptography.ComparisonHarness

Cross-language parity fuzzing harness for TopSecret.Cryptography.Argon2 — compares its output against an independent Python (argon2-cffi) reference implementation across randomized inputs.
