EncryptionClassLib

EncryptionClassLib is a C# library providing easy-to-use, customizable encryption and decryption methods. It supports both AES and RijndaelManaged algorithms with 128-bit and 256-bit key sizes. The library is designed for seamless integration into .NET 6 projects, enabling secure data handling across your applications.

Features

• AES Encryption/Decryption
• 128-bit and 256-bit key support
• Key generation (random or AES-based)
• Asynchronous result wrappers
• RijndaelManaged Encryption/Decryption
• 128-bit and 256-bit key support
• Simple string-based API
• Custom Key Management
• Set and use your own security key
• Result Data Model
• Consistent input/output encapsulation for easy integration

Getting Started

Prerequisites

• .NET 6 or later
• C# 10.0 or later

Installation

Add the project or compiled DLL to your solution.
Add a reference to EncryptionClassLib in your project.

Usage

1. Set the Security Key

EncryptionAsync.GetKey("YourSecretKey123!");

2. Encrypt/Decrypt with AES (128-bit)

// Encrypt
var result = await EncryptionAsync.EncryptionResult128("SensitiveData", null);
Console.WriteLine(result.Output);

// Decrypt
var decrypted = await EncryptionAsync.DcryptionResult128(result.Output, null);
Console.WriteLine(decrypted.Output);

3. Encrypt/Decrypt with AES (256-bit)

var result = await EncryptionAsync.EncryptionResult256("SensitiveData", null);
var decrypted = await EncryptionAsync.DcryptionResult256(result.Output, null);

4. Encrypt/Decrypt with RijndaelManaged (128/256-bit)

string encrypted128 = EncryptionAsync.Encrypt128("SensitiveData", "YourKey");
string decrypted128 = EncryptionAsync.Decrypt128(encrypted128, "YourKey");

string encrypted256 = EncryptionAsync.Encrypt256("SensitiveData", "YourKey");
string decrypted256 = EncryptionAsync.Decrypt256(encrypted256, "YourKey");

5. Custom Key Management

string randomKey = EncryptionAsync.GenerateRandomString(16); // 16 or 32 chars
string aesKey = EncryptionAsync.GenerateAESKey(128); // 128 or 256

• EncryptionAsync.EncryptionResult256(string inputData, string key)
• EncryptionAsync.DcryptionResult256(string encryptionData, string key)
• EncryptionAsync.Encrypt128(string plainText, string key)
• EncryptionAsync.Decrypt128(string encryptedText, string key)
• EncryptionAsync.Encrypt256(string plainText, string key)
• EncryptionAsync.Decrypt256(string encryptedText, string key)

ResultData Model

public class ResultData
{
    public string Input { get; set; }
    public string Output { get; set; }
    public string Key { get; set; }
}

Security Notes

• Always use strong, unique keys for encryption.
• Never hard-code sensitive keys in source code.
• For production, consider secure key storage (e.g., Azure Key Vault, AWS KMS).
