Search the DDV codebase to find all places where certificates are inserted, loaded, or configured. Focus on:

1. Certificate/Keystore Loading: - Search for patterns: "loadKeyPair", "X509Certificate", "readKeyStoreFromFile", "decryptKeyStore" - PKCS12 file handling (.p12, .pfx files) - Certificate import/upload functionality

2. TLS/HTTPS Configuration: - Client certificate configuration - Server certificate handling - Certificate verification settings

3. Module-specific Certificate Usage: - Beyond kbv-ti-connect, check:

   • gematik-crypto module
   • gematik-kim (KIM mail encryption)
   • Any LDAP client configurations
   • Any other German healthcare integrations

4. User-facing Certificate Actions: - UI components for certificate selection - Settings/preferences for certificates - File pickers for certificate files

Search broadly across the codebase. Provide: - File paths where certificates are inserted/loaded - Context about what type of certificate operation is happening - Whether it's similar to the TI Connect keystore decryption we just worked on

Thoroughness level: medium

I'll conduct a comprehensive search across the DDV codebase to find all places where certificates are inserted, loaded, or configured. Let me search systematically across all the key patterns you mentioned.

Perfect! Now let me compile my findings into a comprehensive report. Let me create a summary document based on all the information I've gathered.

Summary of Certificate Operations in DDV Codebase

Based on my comprehensive search of the DDV codebase, I've identified all major places where certificates are inserted, loaded, or configured. Here's the complete analysis:

1. TI Connect Module - PKCS12 Keystore Management

Primary Files: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/kbv-ti-connect/services/keyStore.ts - Operations: Reads PKCS12 files, decrypts keystores, extracts certificate and private key pairs - Key Functions: - readKeyStoreFromFile(keyStorePath) - Reads .p12 files - decryptKeyStore(keyStore, password) - Extracts cert/key pair - getNewKeyStore(oldPath) - Opens file picker for .p12 files

• /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/node/keystore/pkcs12.ts
• Operations: Low-level PKCS12 parsing using node-forge
• Key Functions:
  • getPkcs12(keyStore, keyStorePin) - Parses PKCS12 structure
  • getLatestUserCertificate() - Selects the latest valid certificate by validity period
  • getPrivateKey() - Extracts private key from cert bag
  • getAllCertificates() - Retrieves all certificates in keystore
  • exctractPkCertificatePair() - Converts to PEM format

2. Server Certificate Handling - Connector TLS

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/kbv-ti-connect/services/server-certificate-helpers.ts - Operations: Manages connector server certificates for verification - Key Functions: - getCertificateType(X509Certificate) - Identifies certificate type (C.AUK.AUT, Self-Signed, Externally Generated) - getCAs(serverCertificate) - Returns appropriate CA certificates for verification - createFingerprintVerifier(fingerprint) - Creates server certificate fingerprint validator

3. TI Environment Certificate Provider

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-ti-environment/services/tiEnvCertificateProvider.ts - Operations: Manages environment-specific certificates (RU, PU, TITUS) - Key Functions: - getCertificates() - Returns CA cert and IDP root certificate for TI environment - getDefaultCertificates() - Provides fallback certificates

4. LDAP Client Certificate Configuration

Two Implementation Paths:

A. DoctoCrypt Implementation: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/docto-crypt/ldap/ldapClient.ts - Passes PKCS12 keystore and password via --keystore and --keystore-password flags - Supports server certificate verification via --verify-server-identity and --server-fingerprint

B. Node.js Implementation: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/node/ldap/ldapClient.ts - Direct LDAP client with TLS options

Adapter Pattern: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/crypto-adapter/ldapAdapter.ts - Abstracts between DoctoCrypt and Node.js implementations

5. KIM (Secure Messaging) LDAP Certificate Usage

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-kim/services/client/ldap.ts - Operations: LDAP client initialization with TI connector keystore - Key Functions: - getLdapClientSetup() - Prepares LDAP setup with PKCS12 keystore - instanciateLdapClient() - Creates LDAP client with certificate verification - createLdapClient() - Complete setup with server certificate validation - searchLdap() - LDAP search with TLS

Certificate Flow: Uses TI connector's PKCS12 keystore for LDAP client authentication + server certificate verification

6. HTTPS/TLS Client Certificate Configuration

Primary Files: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/docto-crypt/tls/TLSService.ts - Passes --private-key and --certificate flags to docto-crypt fetch command

• /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/docto-crypt/tls/cryptoHttpClient.ts
• Implements SOAP client HTTP adapter using TLSService
• Passes certificate and key from exoptions parameter

7. Cryptographic Adapter Pattern

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/crypto-adapter/pkcs12Adapter.ts - Dual Implementation: - DoctoCrypt path: Uses keystore extract from-base64 --base64 <keyStore> --password <password> - Node.js path: Uses node-forge for PKCS12 parsing - Functions: exctractPkCertificatePair(), getAllCertificates(), getPrivateKey(), etc.

8. JWT/JWE Cryptographic Operations

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/crypto-adapter/adapter.ts - Key Operations: - JWKKeyStore.loadKeyPair(x509CertificatePem, privateKeyPem) - Load certificate for JWT operations - JWKKeyStore.loadPublicKey(x509Certificate) - Extract public key - Handles both symmetric keys and ECC keys for JWE encryption/decryption

9. IDP Authentication Certificate Handling

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-idp-authentication/services/idpPublicKeys.ts - Operations: Fetches and extracts IDP public keys - Key Functions: - IdpPublicKeys.fetch() - Retrieves signing certificates and encryption keys from IDP JWKS endpoint - Returns: SignatureVerificationAndEncryptionKey (signing certificate + encryption key)

10. MSsante (French Healthcare) Certificates

Primary File: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/mssante/main/mssante-certificates.ts - Operations: Hardcoded trusted CA certificates for French healthcare system - Includes: - ACI_EL_PP_CRT (AC IGC-SANTÉ for individuals) - ACI_EL_ORG_CRT (AC IGC-SANTÉ for organizations) - ACR_EL_CRT (AC RACINE IGC-SANTÉ) - Test variants for development/staging

11. User-Facing Certificate Actions

Primary Files:

TI Connect Preferences UI: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/kbv-ti-connect/renderer/components/preferences/sections/TIConnect.tsx - Toggle for certificate verification (isCertificatesVerificationEnabled) - Settings for connector certificate verification mode

File Picker for Certificates: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/gematik-crypto/services/node/keystore/keystoreFile.ts - KeystoreFile.read(keyStorePath) - Reads binary keystore file - KeystoreFile.defineNewPath() - Opens Electron file picker for .p12 files

12. TI Connect Configuration & Settings

Primary Files: - /Users/USER/workspace/doctolib/FHIR-1996_track-ecc-rsa-certificate-usage/src/modules/kbv-ti-connect/services/ti-connect-helper.ts - getClientCertificateAndKey() - Retrieves loaded client cert, key, and server cert settings - Returns: cert, key, isCertificatesVerificationEnabled, serverCertificate, serverCertificateFingerprint
