Vimes.SignSDK

A lightweight, infrastructure-agnostic library for digital signature integration. This SDK supports multiple merchants (SmartCA, Viettel MySign, VNPT, USB Token, etc.) and provides a simplified interface for signing PDF documents using purely file-system and in-memory operations.

🚀 Quick Start

1. Installation

Install the package via NuGet:

dotnet add package Vimes.SignSDK

2. Configuration

Add the following configuration to your appsettings.json. The SDK is now database-free and uses local storage for temporary files and logs.

{
  "InternalSetting": {
    "HospitalName": "Your Hospital",
    "CompanyName": "Your Company",
    "DefaultMerchantId": "VIETTEL",
    "SignatureMode": 0,
    "IsEnableRegisterExtension": true
  },
  "FileStorageSetting": {
    "WebRootFallback": "wwwroot",
    "ExportFolderName": "export",
    "CertsFolderName": "certs"
  },
  "MySignSetting": {
    "BaseUrl": "https://remotesigning.viettel.vn",
    "ProfileId": "your-profile-id",
    "ClientId": "your-client-id",
    "ClientSecret": "your-client-secret"
  },
  "CacheSetting": {
    "Backend": "Memory"
  }
}

3. Dependency Injection

Register the SignSDK services in your Program.cs. The SDK requires standard ASP.NET Core environment and logging services.

using SignSDK;

var builder = WebApplication.CreateBuilder(args);

// Register the infrastructure-agnostic SignSDK
builder.Services.AddSignSDK(builder.Configuration);

var app = builder.Build();

4. Basic Usage

Inject ISignSDKClient to start signing documents programmatically:

public class MyHospitalService
{
    private readonly ISignSDKClient _signClient;

    public MyHospitalService(ISignSDKClient signClient)
    {
        _signClient = signClient;
    }

    public async Task SignPatientRecord(string userName, string password, byte[] pdfData)
    {
        // 1. Login to merchant
        var session = await _signClient.LoginAsync(userName, password, "VIETTEL");
        if (!session.Success) throw new Exception(session.ErrorMessage);

        // 2. Get available certificates
        var certs = await _signClient.GetCertificatesAsync(userName, session.BearerToken);
        
        // 3. Sign the document
        var result = await _signClient.SignDocumentAsync(new SignDocumentRequest
        {
            UserName = userName,
            MerchantId = "VIETTEL",
            CredentialID = certs[0].credentialID,
            FileName = "record.pdf",
            FileData = Convert.ToBase64String(pdfData),
            SignerName = "Dr. Smith",
            Page = 1,
            X = 100, Y = 100, Width = 150, Height = 75
        });

        if (result.Success) {
            Console.WriteLine($"Signed file: {result.SignedFileUrl}");
        }
    }
}

📦 Architecture (Lightweight Version)

  • Infrastructure Agnostic: Zero dependency on EF Core, SQL Server, or PostgreSQL.
  • Stateless Operation: No internal database state. Host applications manage their own persistence.
  • Zero-Redis: Uses MemoryCache by default for session and certificate caching.
  • File-Based Logging: Audit logs and signatures are tracked via Serilog text sinks.
  • Merchant Plugins: Includes built-in support for major Vietnamese CAs via a plugin-based architecture.
