CryptoHives.Foundation.Security.Cryptography
Fully managed, OS-independent implementations of cryptographic hash, MAC, KDF, and cipher algorithms for .NET — written from NIST/RFC/ISO specifications and verified against official test vectors.
No OS crypto dependency — deterministic results on every platform. Hardware acceleration via AES-NI, PCLMULQDQ, VPCLMULQDQ, SSE2, SSSE3, and AVX2 intrinsics is automatically enabled on supported hardware.
📦 Installation
dotnet add package CryptoHives.Foundation.Security.Cryptography
✨ Key Features
- OS-independent — identical results on Windows, Linux, macOS, and any .NET-supported platform
- Standards-based — implemented from NIST, RFC, and ISO specifications; validated against official test vectors
- Hardware-accelerated — automatic AES-NI, AVX2, SSSE3 dispatch; scalar fallback always available
- Allocation-free hot paths —
Span<byte>-based APIs,stackalloc-friendly - XOF streaming —
IExtendableOutputinterface (Absorb/Squeeze/Reset) on all XOF algorithms HashAlgorithmcompatible — drop-in for any existingSystem.Security.Cryptography.HashAlgorithmconsumer- Comprehensive algorithm coverage — SHA-2/3, Keccak, SHAKE, BLAKE2/3, Ascon, regional ciphers, and more

🚀 Quick Examples
Allocation-Free Hash (Blake3)
using CryptoHives.Foundation.Security.Cryptography.Hash;
using var blake3 = Blake3.Create();
Span<byte> hash = stackalloc byte[32];
blake3.TryComputeHash(data, hash, out _);
XOF Streaming (Shake256)
using CryptoHives.Foundation.Security.Cryptography.Hash;
// Variable-length output via IExtendableOutput
using var shake = Shake256.Create(outputLength: 64);
shake.Absorb(context);
shake.Absorb(message);
Span<byte> output = stackalloc byte[64];
shake.Squeeze(output);
shake.Reset(); // Reuse the instance
Keyed Hash / MAC (HMAC-SHA-256)
using CryptoHives.Foundation.Security.Cryptography.Mac;
using var hmac = new HmacSha256(key);
Span<byte> tag = stackalloc byte[32];
hmac.TryComputeHash(message, tag, out _);
Authenticated Encryption (AES-GCM)
using CryptoHives.Foundation.Security.Cryptography.Cipher;
using var aesGcm = new AesGcm256(key);
// Encrypt
Span<byte> ciphertext = new byte[plaintext.Length];
Span<byte> tag = stackalloc byte[16];
aesGcm.Encrypt(nonce, plaintext, ciphertext, tag, associatedData);
// Decrypt — throws if tag verification fails
Span<byte> recovered = new byte[ciphertext.Length];
aesGcm.Decrypt(nonce, ciphertext, tag, recovered, associatedData);
cSHAKE — Domain-Separated XOF
using CryptoHives.Foundation.Security.Cryptography.Hash;
using var cshake = CShake128.Create(
functionName: "MyApp"u8,
customization: "v1"u8,
outputLength: 32);
cshake.Absorb(input);
Span<byte> derived = stackalloc byte[32];
cshake.Squeeze(derived);
