Updated `PdfSignOptionsDto` and `PdfSignatureCheckItemDto` to use `DocumentElementId` (long) instead of `UUID` (string). Modified `PdfDigitalSignatureService` to reflect this change, including updates to `SignatureReasonMetaRegex`, `BuildReasonWithMeta`, and `ParseReasonMeta`. Adjusted method signatures, return values, and property assignments to ensure consistent use of `DocumentElementId`. These changes align with a shift in the application's data model to use numeric identifiers for document elements.
Refactored `Pkcs11Options` by removing `DefaultCertificationLevel` and improving property documentation. Replaced `VisualSignature` in `PdfSignOptionsDto` with `Appearance` using the new `PdfSignatureAppearanceDto` class, which encapsulates signature appearance details, including font and color settings.
Enhanced `PdfSignatureCertificationLevel` enum with more descriptive values and added XML documentation. Updated `IPdfDigitalSignatureService` to support optional signature images and removed redundant methods.
Refactored `PdfDigitalSignatureService` to streamline appearance handling, validate inputs, and improve maintainability. Removed unused methods and added support for `PdfSignatureAppearanceDto`.
Simplified `PdfSignatureController` by consolidating form properties into `PdfSignOptionsDto`. Improved code readability and flexibility while removing redundant logic.
Refactored `PdfSignOptionsDto` and `PdfVisualSignatureOptionsDto`:
- Converted both to immutable `record` types with non-nullable properties.
- Added XML documentation comments for properties and parameters.
Simplified `PdfDigitalSignatureService`:
- Updated `SignPdfAsync` to enforce non-nullable `PdfSignOptionsDto`.
- Removed redundant null checks and inlined `CreateSignatureBounds`.
- Simplified signature appearance and image data logic.
- Refactored `TryGetKeySize` to use `bool` with `out` parameter.
General improvements:
- Enhanced code readability and maintainability.
- Reduced nullable references and enforced stricter type safety.
Enhanced `PdfSignOptionsDto` with a `VisualSignature` property and introduced the `PdfVisualSignatureOptionsDto` class for configuring visual signature options. Updated `PdfDigitalSignatureService` to handle visual signatures, including page number resolution, signature bounds calculation, and appearance customization.
Refactored `PdfSignatureController` to support visual signatures by extending `SignPdfForm` with `SignatureImageFile` and `VSignature` properties. Improved validation for page numbers and signature dimensions. Streamlined `Sign` and `IsSigned` endpoints for better clarity and reduced redundancy.
Added XML documentation for improved API clarity and performed general code cleanup to enhance maintainability.
Replaced the `ContactInfo` property with separate `Email` and `Phone` fields in `PdfSignOptionsDto` and `PdfSignatureCheckItemDto` for better granularity. Updated the `PdfDigitalSignatureService` to handle the new fields, introducing `BuildContactInfo` and `ParseContactInfo` methods for constructing and parsing contact information.
Modified the `PdfSignatureController` to reflect these changes, updating request models and the `SignPdfAsync` method. Updated the `README.md` to document the new structure. These changes improve the clarity and structure of contact information handling.
The `SigningTime` property has been removed from the `PdfSignOptionsDto` class and related client-side input handling. It is now set automatically on the server side based on the `UseUtcSigningTime` configuration (`UtcNow` or local time).
Updated the `PdfDigitalSignatureService` to always set `SigningTime` server-side, ensuring consistent and deterministic behavior. Removed `SigningTime` from the `PdfSignatureController` and adjusted the logic to exclude it from the `signOptions` object.
Updated the `README.md` to reflect these changes, clarifying that `SigningTime` is now server-side only. These changes improve security and simplify client integration.
Enhanced PDF signing with UUID and metadata handling:
- Added `UUID` and `OriginalDocumentSha256` to `PdfSignOptionsDto` and `PdfSignatureCheckItemDto`.
- Introduced `BusinessReason` to separate metadata from signature reasons.
- Updated `PdfDigitalSignatureService` to embed and parse metadata in signature reasons.
- Improved error handling to include metadata in validation results.
- Updated `PdfSignatureController` to handle `UUID` in signing requests.
Refactored PKCS#11 configuration:
- Replaced `LibraryPath` with `AssetsRootPath` for asset resolution.
- Added `ProxySocket` and `DefaultApplicationName` options.
- Clarified runtime behavior for asset resolution in `README.md`.
Updated documentation and examples to reflect these changes.
Introduced `Pkcs11Options` for configuring PKCS#11 signing workflows, including properties for library path, token selection, and signing metadata. Added `PdfSignOptionsDto` to represent signing options and `PdfSignatureCheckResultDto` with related DTOs for signature validation.
Defined `PdfSignatureCertificationLevel` enum for certification levels. Added `IPdfDigitalSignatureService` interface to support signing and validating PDF signatures. These changes enable robust and extensible handling of digital signatures.
