Security.Encryption.AES

Security.Encryption.AES is a .NET library providing easy-to-use, secure AES encryption and decryption utilities. It supports both AES-GCM (Galois/Counter Mode) and AES-CBC (Cipher Block Chaining) modes, making it suitable for a wide range of cryptographic scenarios.

Table of Content

Functionalities

  • AES-GCM Encryption/Decryption: Authenticated encryption for modern security needs.
  • AES-CBC Encryption/Decryption: Traditional block cipher mode with PKCS7 padding.
  • Key and IV management: Secure handling of cryptographic keys and initialization vectors.
  • Dynamic Key usage: You provide the key to be used, so the key is not stored for other purposes or generated.
  • Easy to use: Easy integration with your .NET projects.
  • Builder Pattern: Use the SecureEncryptionBuilder to configure and instantiate ciphers.

How to Install

Add the library to your project using the .NET CLI:

dotnet add package Security.Encryption.AES

Usage / Implementation

1. Create an Encryptor

using Security.Encryption.AES;
using Security.Encryption.AES.Enums;

byte[] key = Convert.FromBase64String("your-base64-key-here");

var cipher = new SecureEncryptionBuilder()
    .WithKey(key)
    .WithMode(AesEncryptionMode.GCM)
    .Build();

2. Encrypt Data

string plainText = "Sensitive Data";
byte[] encrypted = cipher.Encrypt(plainText);

3. Decrypt Data

string decrypted = cipher.Decrypt(encrypted);

Example with CBC Mode

var cbcCipher = new SecureEncryptionBuilder()
    .WithKey(key)
    .WithMode(AesEncryption.CBC)
    .Build();

byte[] encrypted = cbcCipher.Encrypt("Another secret");
string decrypted = cbcCipher.Decrypt(encrypted);

For more details see the interfaces ISecureEncryption and IGcmSecureEncryption.
