PanoramicData.LicenceMagic

Introduction

PanoramicData.LicenceMagic is a .NET 10 library for creating, signing, writing, reading, and validating application licence files.

Licence signatures are bound to a filename and validated against the licensed company, product, validity dates, and assembly version range.

Installation

dotnet add package PanoramicData.LicenceMagic

Usage

Define licence details with a fixed 16-byte initialization vector:

using PanoramicData.LicenceMagic;

public sealed class ProductLicence : LicenceDetails
{
	private static readonly byte[] InitVector =
		[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];

	public ProductLicence() : base(InitVector)
	{
	}
}

Create and write a signed licence:

var salt = new byte[] { 0, 1, 2, 3, 4, 5, 6, 7 };
var file = new FileInfo("product.lic");
var details = new ProductLicence
{
	LicensedCompany = "Example Ltd",
	LicensedProduct = "Example Product",
	StartDateUtc = DateTime.UtcNow.Date,
	EndDateUtc = DateTime.UtcNow.Date.AddYears(1),
	StartVersion = "1.0",
	EndVersion = "2.0"
};

details.Sign(file.Name, salt);
new License<ProductLicence>(details).WriteToFile(file, salt);

Read and validate it:

var licence = new License<ProductLicence>(file);
var validation = licence.Validate(salt);
if (!validation.IsValid)
{
	throw new InvalidOperationException(validation.ErrorMessage);
}

Keep the salt and initialization vector stable and protect them as application secrets. Existing licence files depend on the values used when they were signed.
