Replaced the previous signature persistence mechanism with
`IMemoryCache` for temporary storage of captured signatures
using a unique `Guid` key and a 1-minute TTL. Added logging
to track cached signatures and their associated envelope keys.
Removed the logic for rebuilding and displaying reports with
overlaid signatures. Instead, implemented navigation to a
new signed page (`/envelope/{EnvelopeKey}/signed`) with the
signature ID passed as a query parameter.
Added a `PdfSharpFontResolver` class to enable font resolution
for PdfSharp in .NET 8, addressing the lack of system font
access. The resolver reads fonts from the Windows Fonts folder
and supports the Arial font family. Registered the resolver
globally in `Program.cs` using `GlobalFontSettings.FontResolver`.
Updated `Program.cs` with comments explaining the necessity of
the resolver for .NET 8. The resolver includes methods to map
font family names to specific font files and load font data.
Throws a `FileNotFoundException` if required fonts are missing.
Made minor formatting changes in `Program.cs` without altering
the `SwaggerDoc` description functionality.
Refactored `EnvelopeReceiverReportPage.razor` to replace the logic for burning captured signatures with a new approach that draws placeholder boxes for signature fields using the `DrawSignaturePlaceholders` method. Removed the `BurnSignaturesIntoPdf` method and introduced `PDFsharp` for rendering placeholders.
Added `EnvelopeReceiverReportSignedPage.razor` to handle signed envelopes, including a detailed UI for document display, metadata, and a signature popup with "Draw," "Text," and "Image" modes. Integrated JavaScript interop for signature creation and validation.
Updated `EnvelopeGenerator.Server.csproj` to include the `PDFsharp` library. Enhanced error handling, logging, and UI feedback. Improved code readability and maintainability through cleanup and refactoring.
Replaced iText-based PDF processing with DevExpress PdfGraphics API.
Removed `itext` and `itext.bouncy-castle-adapter` dependencies.
Simplified `BuildReport` to burn signatures directly into PDFs
and render all pages using `XRPdfContent` with `GenerateOwnPages = true`.
Consolidated subreport logic into `BuildReport` and removed
`BuildPageSubreport`. Eliminated unused constants and methods,
including `GetPdfPageCount`. Updated XML documentation to reflect
the new implementation. Placeholder implementation for
`BurnSignaturesIntoPdf` added, pending further development.
Added a new Razor page `EnvelopeReceiverReportPage.razor` to display and manage envelope reports at the route `/envelope/{EnvelopeKey}/report`. Integrated DevExpress Blazor Reporting components (`DxReportViewer`, `DxPopup`) for rendering PDF documents and capturing user signatures.
Implemented a multi-tab signature capture interface supporting drawing, text input with font selection, and image uploads. Added support for dynamically overlaying captured signatures on PDF documents using `XRPictureBox`.
Introduced dependency injection for services like `AuthService`, `ReceiverAuthorizationService`, and `PageDataService` to handle authentication, data retrieval, and logging. Included lifecycle methods for user authorization, PDF loading, and restoring cached signatures.
Added validation for signature input, error handling for missing data, and utility methods for building reports, extracting PDF page counts, and converting base64 data URLs. Integrated JavaScript interop for canvas-based signature handling.
Included custom styles and assets, and implemented disposal logic for cleaning up resources.
Refactored the logic to filter and map `elements` to `signatures`
before converting them to `UnitOfLength.Point`. Removed the direct
return of `elements` and ensured that only the processed `signatures`
are converted and returned. Added a `ToList()` call to materialize
the `signatures` collection before conversion.
Refactored `EnvelopeReceiverPage.razor` to use new services for receiver authentication and data retrieval. Introduced `EnvelopeReceiverAuthorizationService` for handling JWT-based authorization and `EnvelopeReceiverPageDataService` for centralized data access and caching. Updated dependency injection in `Program.cs` to register these services.
Replaced direct service calls with `PageDataService` methods for document, signature, and receiver data retrieval. Improved logging with `ILogger` and added debug logs for token validation. Enhanced modularity, maintainability, and performance by consolidating logic and reducing coupling between components.
Modified the `[Authorize]` attribute in `EnvelopeController` to use `AuthScheme.Sender` for authentication. Updated `Program.cs` to configure JSON serialization with `ReferenceHandler.IgnoreCycles` to handle circular references.
Added new CSS styles for the sender dashboard in `sender-page.css`, including layout, action bars, buttons, tabs, badges, and responsive design improvements. Enhanced button states and introduced styles for status indicators and receiver badges.
Updated `EnvelopeSenderPage.razor` to replace the `[Authorize]`
attribute with the `@rendermode InteractiveWebAssembly` directive,
indicating a shift in how authorization or rendering is handled.
Modified the `Check` method in `AuthController.cs` to specify
`AuthenticationSchemes = AuthScheme.Sender` in the `[Authorize]`
attribute, enforcing a more specific authentication scheme for
this endpoint.
Replaced the `Address` value for the `primary` destination in the
`auth-hub` cluster within `yarp.json`. The previous value
(`https://localhost:9090`) was updated to
`http://172.24.12.39:9090`, reflecting a move from a local
development environment to a specific networked environment.
The protocol was also changed from `https` to `http`.
Refactored `DocReceiverElementService` and `EnvelopeService` to use `IHttpClientFactory` instead of directly injecting `HttpClient`, improving flexibility and testability.
Updated constructors to accept `IHttpClientFactory` and replaced direct `HttpClient` usage with named clients (`"EnvelopeGenerator.Server"`). Adjusted methods to use the factory-created clients for HTTP requests.
Added `using Microsoft.Extensions.Options;` in `Program.cs` and registered `EnvelopeService` and `DocReceiverElementService` in the dependency injection container for proper resolution. Clarified their usage in SSR scenarios with comments.
Removed redundant `using` directives and aligned imports with the updated implementation.
These changes enhance maintainability, scalability, and testability by leveraging `IHttpClientFactory` for better HTTP client management and dependency injection.
Refactor `DocumentController.GetDocument` to exclusively support the "Sender" role by removing logic for the "Receiver" role. Update the `[Authorize]` attribute to enforce the `AuthPolicy.Sender` policy instead of `AuthPolicy.SenderOrReceiver`.
Remove the `AuthPolicy.SenderOrReceiver` policy from `Program.cs` authorization configuration, reflecting the decision to separate role-based access more explicitly. The application now defines distinct policies for "Sender" and "Receiver" roles without combining them.
- Added project reference to `EnvelopeGenerator.Application` in the client project.
- Updated imports and injected services in `EnvelopeSenderPage.razor`.
- Improved null handling for `EnvelopeReceivers` and updated email display logic.
- Replaced `CheckSenderAsync` with `CheckSenderAccessAsync` for authorization.
- Refactored `GetStatusInfo` to use `EnvelopeStatus` enum directly.
- Added `CheckSenderAccessAsync` and `LogoutSenderAsync` methods in `AuthService`.
- Simplified `Logout` logic in `AuthController` to remove redundant checks.
The `Auth` record in the `EnvelopeGenerator.Server.Models`
namespace has been marked as `[Obsolete]` with the message
"Use auth DTO" to indicate it is outdated and should be
replaced with a newer implementation.
The `Auth` record includes the following properties:
- `AccessCode`, `SmsCode`, `AuthenticatorCode` (nullable strings)
- `UserSelectSMS` (boolean)
Additionally, it defines computed properties `HasAccessCode`
and `HasSmsCode` to check for the presence of `AccessCode`
and `SmsCode`, respectively.
- Replaced `SignatureService` with `DocReceiverElementService` in DI.
- Refactored `envelope-action-bar` for better readability and added badges for `2FA`, `Access Code`, and `Signature Count`.
- Improved error handling and loading states with clearer messages.
- Enhanced PDF viewer toolbar with better navigation, zoom, and signature controls.
- Added resizable thumbnail sidebar with persistent width settings.
- Refactored signature popup to support draw, text, and image tabs with validation.
- Improved JavaScript interop for PDF rendering and signature handling.
- Introduced DevExpress PDF Viewer as an alternative implementation.
- Consolidated state management and improved code readability.
Introduced `EnvelopeAuthService` and `IEnvelopeAuthService` to handle server-side authentication for envelope receiver pages.
- Registered `IEnvelopeAuthService` as a scoped service in `Program.cs`.
- Implemented `EnvelopeAuthService` to validate user authentication and envelope key matching using `IHttpContextAccessor` and JWT claims.
- Added methods to retrieve the authenticated envelope key and current user (`ClaimsPrincipal`).
- Prioritized `NameIdentifier` claim for envelope key extraction, with fallback to `sub` claim.
- Documented the service and interface with XML comments for clarity.
This centralizes authentication logic, ensuring reusability and adherence to SSR best practices.
Added the `Yarp.ReverseProxy` package and configured the app to use
YARP for forwarding specific authentication-related API requests
to an external service (`auth-hub`). Updated `Program.cs` to load
YARP configuration from a new `yarp.json` file and added middleware
to map unmatched requests to the reverse proxy.
Replaced old routes and clusters with new routes (`auth-login`,
`auth-envelope-receiver-login`) and a new cluster (`auth-hub`)
pointing to `https://localhost:9090`. Configured route
transformations for path and query parameter adjustments.
These changes improve modularity and scalability by enabling
dynamic reverse proxy configuration and external service
integration.
Moved HttpContextAccessor registration into the configuration
of the named HttpClient ("EnvelopeGenerator.Server") to support
server-side rendering (SSR) scenarios. Updated the HttpClient
to dynamically set its BaseAddress based on the current request's
scheme and host using HttpContextAccessor. Removed standalone
HttpContextAccessor registration and updated related comments.
Updated DependencyInjection.cs to change ISmsSender and
IEnvelopeSmsHandler lifetimes from Singleton to Scoped,
ensuring per-request instantiation. Added Microsoft.Extensions.Http
package to EnvelopeGenerator.Server.Client.csproj for enhanced
HttpClient handling. Refactored AnnotationService, AuthService,
DocumentService, EnvelopeReceiverService, SignatureCacheService,
and SignatureService to use IHttpClientFactory, improving
flexibility and testability. Introduced a named HttpClient
"EnvelopeGenerator.Server" in Program.cs for internal API calls,
and removed the previous HttpClient setup using HttpContextAccessor.
Added necessary using directives for System.Net.Http across
service files to support these changes.
Renamed namespaces and related identifiers from EnvelopeGenerator.WebUI
to EnvelopeGenerator.Server across the project. This change affects
data models, services, controllers, and configuration files to ensure
consistency with the new architecture.
Updated @using directives in Razor components and other files to
reflect the new namespace structure. Adjusted project references in
EnvelopeGenerator.Server.csproj to point to the new
EnvelopeGenerator.Server.Client project.
Modified middleware and logging configurations to use the new
EnvelopeGenerator.Server namespace, including changes in Program.cs
and appsettings.json.
Updated resource and file references to use the new
EnvelopeGenerator.Server path, ensuring correct resource loading.
Adjusted configuration options in Program.cs to use the new namespace
for options classes, such as ApiOptions and PdfViewerOptions.
Updated authentication scheme names and related constants to align
with the new namespace structure.
Revised comments and documentation to reflect the new namespace,
ensuring clarity and consistency in the codebase.
Replaced "EnvelopeGenerator.WebUI" with "EnvelopeGenerator.Server" and "EnvelopeGenerator.WebUI.Client" with "EnvelopeGenerator.Server.Client". Updated project entries, solution configuration platforms, and nested projects to reflect these changes.
