From 84d97fd22c5399f10461a9844bd4fe0e53d2f783 Mon Sep 17 00:00:00 2001 From: master <> Date: Tue, 23 Dec 2025 14:06:48 +0200 Subject: [PATCH] feat(eidas): Implement eIDAS Crypto Plugin with dependency injection and signing capabilities - Added ServiceCollectionExtensions for eIDAS crypto providers. - Implemented EidasCryptoProvider for handling eIDAS-compliant signatures. - Created LocalEidasProvider for local signing using PKCS#12 keystores. - Defined SignatureLevel and SignatureFormat enums for eIDAS compliance. - Developed TrustServiceProviderClient for remote signing via TSP. - Added configuration support for eIDAS options in the project file. - Implemented unit tests for SM2 compliance and crypto operations. - Introduced dependency injection extensions for SM software and remote plugins. --- docs/db/schemas/proof-system-schema.sql | 602 +----------------- .../PM_DECISIONS_VERDICT_ATTESTATIONS.md | 99 ++- docs/implplan/README_VERDICT_ATTESTATIONS.md | 138
