ETAMP Protocol - Encrypted Token and Message Protocol

ETAMP Documentation

NuGet Package

Introduction

ETAMP (Encrypted Token and Message Protocol) is a comprehensive .NET library tailored for secure message and token encryption and validation. Utilizing the power of elliptic curve cryptography (ECC), ETAMP offers a robust solution for ensuring the security of digital communication. The library is designed with flexibility in mind, allowing for the generation of customizable signed tokens and secure message transmissions.

Features

• Advanced Cryptography: Leverages ECC for digital signatures, ensuring high-security standards.
• Token Generation: Create signed or unsigned tokens with user-defined payloads, suitable for various secure data transmission needs.
• Token Validation: Robust methods to validate the authenticity and integrity of tokens.
• JWT Integration: Supports JSON Web Tokens (JWT) with claims validation for integrity and lifetime verification.
• Customization: Flexible architecture supports custom curves, keys, and algorithms.

Installation

Install ETAMP via NuGet Package Manager:

Install-Package ETAMP

Usage Examples

Creating ETAMP Tokens

var etamp = new Etamp();

public class Order : BasePayload {
    public string ItemName { get; set; }
    public decimal Price { get; set; }
}

string token = etamp.CreateETAMP("order", new Order(), true, 1.0);

Validating ETAMP Tokens

var validator = new ValidateToken(new VerifyWrapper(new EcdsaWrapper()));
bool valid = validator.VerifyETAMP(token);

Cryptographic Components

• EcdsaWrapper: A factory class for creating ECDsa instances.
• VerifyWrapper: Handles cryptographic verification processes.
• Flexible Security: Supports integration with hardware security modules.

Additional Features

• Lightweight validation methods focusing on cryptographic checks.
• Methods for verifying JWT properties like lifetime, issuer, and audience.
• Integrates seamlessly with existing .NET applications.
