gcrypt

A .NET Core/Framework library for all your encryption needs.

Installation

To use gcrypt in your C# project, you can either download the gcrypt C# .NET libraries directly from the Github repository or, if you have the NuGet package manager installed, you can grab them automatically.

PM> Install-Package gcrypt

Once you have the gcrypt libraries properly referenced in your project, you can include calls to them in your code.

Add the following namespaces to use the library:

using gcrypt;
using gcrypt.Providers;

Usage

The below code can be used in a .NET project.

public class Program
{
	public static void Main(string[] args)
	{
		gcrypter.Initialize();

		string originalString = Guid.NewGuid().ToString();

		string encryptedString = gcrypter.Encrypt(originalString);

		string decryptedString = gcrypter.Decrypt(encryptedString);
	}
}

By default gcrypt is intialized with a TripleDESProvider as

new TripleDESProvider( "gcrypt", CipherMode.ECB, PaddingMode.PKCS7 )

But you can initialize it with your own set of values :

gcrypter.Initialize( new TripleDESProvider( "MyOwnKey", CipherMode.CFB, PaddingMode.ANSIX923 ) );

Stack Multiple Providers :

gcrypter.Initialize( new TripleDESProvider("MyOwnKey", CipherMode.CFB, PaddingMode.ANSIX923 )
	 , new Base64Provider()
	 , new ReverseProvider(5) );

Once initialized Encrypt / Decrypt methods will use these providers in their order.

Create Your Own Providers

You can create a Provider by Implementing ICryptProvider.

public class MyProvider : ICryptProvider
{
	public MyProvider(string config)
	{
		//SOME CODE
	}

	public string Encrypt(string originalString)
	{
		//SOME CODE
	}

	public string Decrypt(string encryptedString)
	{
		//SOME CODE
	}
}

And use them something like this :

gcrypter.Initialize( new MyProvider("SOME CONFIG")
		 , new Base64Provider()
		 , new TripleDESProvider("MyOwnKey", CipherMode.CFB, PaddingMode.ANSIX923)
		 , new ReverseProvider(5));
