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.
Updated README.md for clarity and added official references. Introduced detailed infrastructure and integration plans for FES, including phased implementation, deployment options, and risk mitigations. Added FES workflow diagrams in draw.io and PDF formats. Documented SoftHSM testing process and integration details in ticket.md. Improved alignment with clean architecture principles and production readiness.
Added a detailed README for the `EnvelopeGenerator.Infrastructure.Crypt` project, explaining its purpose, functionality, and integration with PKCS#11-based cryptographic workflows.
Highlights include:
- Overview of the project's role in FES workflows.
- Explanation of SoftHSM and PKCS#11 deployment patterns.
- Mapping of functionality to FES diagram steps 6-8.
- Documentation of service interfaces and DI entry point.
- Configuration guidance with JSON examples and security best practices.
- Instructions for obtaining PKCS#11 values and setting up SoftHSM.
- Checklist for IT handover and environment setup.
- Steps for running cryptographic tests with PowerShell and Linux examples.
- Common failure diagnostics and their meanings.
- Clarification of signing semantics and validation requirements.
- FAQ addressing common questions about SoftHSM and PKCS#11 usage.
This update ensures clear guidance for developers and IT teams to configure and integrate the cryptographic layer effectively.
