Easy.Tools.Security

Easy.Tools.Security is a lightweight .NET library designed to simplify common cryptographic operations. It focuses on generating secure random passwords and computing hashes (SHA256, SHA512) with a clean, developer-friendly API.

Features

• Secure Password Generator: Uses RandomNumberGenerator (CSPRNG) instead of System.Random to ensure passwords are unpredictable and secure.
• Customizable Rules: Generate passwords with specific requirements (Uppercase, Numbers, Special Characters, etc.).
• Hashing Utilities: Quick helpers for SHA-256 and SHA-512 computations.
• Thread Safe: Can be used safely across concurrent applications.

Installation

Install via NuGet Package Manager:

Install-Package Easy.Tools.Security

Or via .NET CLI:

dotnet add package Easy.Tools.Security

Usage Example

1. Generating a Secure Password

Simple usage with default settings (12 chars, all types included):

using Easy.Tools.Security; string password = PasswordGenerator.Generate(); Console.WriteLine(password); // Output: "aK9#m!vL2$xP"

2. Custom Password Configuration

Generate a pin code or a specific format:

var options = new PasswordOptions { Length = 8, IncludeUppercase = false, IncludeLowercase = false, IncludeNumbers = true, IncludeSpecialChars = false }; string pinCode = PasswordGenerator.Generate(options); Console.WriteLine(pinCode); // Output: "82910453"

3. Computing Hashes

Useful for verifying file integrity or legacy authentication systems.

string input = "Hello World"; string hash = HashHelper.ComputeSha256(input); Console.WriteLine(hash); // Output: "a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e" return Ok(result.Value);

Security Note

This library uses System.Security.Cryptography.RandomNumberGenerator for password generation, which is suitable for cryptographic use cases. It avoids the pitfalls of using System.Random which is predictable.
