Decode.Cryptography

Modern and secure cryptography utilities for .NET, providing a clean API for common cryptographic operations.

🚀 Features

  • Secure Password Hashing (PBKDF2): Key derivation using HMAC-SHA256 with 100,000 iterations by default (OWASP recommended).
  • Timing Attack Protection: Uses CryptographicOperations.FixedTimeEquals for all verification methods.
  • HMAC: Message authentication using SHA256.
  • SHA256: Standard hashing with support for multiple iterations.
  • HEX & Base64: Optimized conversions for cryptographic data using modern .NET primitives.
  • Modern .NET: Fully optimized for .NET 8/9 using Span<byte> and native HEX conversions.

📖 Usage

Hashing a Password (PBKDF2)

This is the recommended way to store user passwords.

using Decode.Cryptography;

// Generate a unique salt for the user
string salt = Hash.GenerateSaltToBase64String();

// Hash the password with the salt
string hash = Hash.HashPasswordToBase64String("user-password", salt);

// Store both 'salt' and 'hash' in your database

Computing HMAC-SHA256

// hexKey must be a valid hexadecimal string
string hmac = Hash.ComputeHmacSha256ToBase64String(hexKey, "content");

HEX Conversions

byte[] data = [0xDE, 0xAD, 0xBE, 0xEF];

// Convert to HEX string
string hex = Utils.ToHexString(data);

// Convert back to byte array
byte[] back = Utils.FromHexString(hex);

🔒 Security Note

This library follows modern security standards:

  • No MD5/SHA1: Insecure algorithms are not included.
  • Constant-Time Comparison: Prevents side-channel timing attacks during hash verification.
  • High Iteration Count: Protects against modern GPU-based brute-force attacks.
