Find the CertificateService implementation that's used in VauValidation.verifyCertificate(). I need to understand: 1. Where is CertificateService located? 2. What methods does it provide? 3. Does it support OCSP or revocation checking? 4. What are the parameters and return types? 5. How does it interact with the TI Connector?

Look in the gematik-related modules, particularly anything related to certificate validation or the connector.

Perfect! Now I have all the information I need. Let me create a comprehensive analysis document:

Summary

I've thoroughly explored the CertificateService implementation and its integration with VauValidation. Here's a comprehensive analysis:

1. Location of CertificateService

File Path: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/kbv-ti-connect/services/certificate-service/

Structure: - Main Implementation: soap-client.ts (429 lines) - Export: index.ts (simple re-export) - WSDL Definition: ../connector-wsdls/conn/CertificateService_v6_0_1.wsdl - XSD Schema: ../connector-wsdls/conn/CertificateService_v6_0_2.xsd

2. Methods Provided by CertificateService

The CertificateService is implemented as a static utility class with the following public methods:

Primary Methods:

1. verifyCertificate(configurationService, traceId?, certificate?) - Purpose: Verifies the validity of an X.509 certificate - Parameters:

   • configurationService: ConfigurationService - Contains connector context
   • traceId?: string (default: 'unknown') - For logging/tracking
   • certificate?: string - Base64-encoded X.509 certificate
   • Returns: Promise<VerifyCertificateResponseMessage>
   • Throws: Error if certificate is null/undefined

2. readCardCertificate(configurationService, traceId?, cardHandle?, certRefList?, crypt?) - Purpose: Reads X.509 certificates from an inserted card - Parameters:

   • configurationService: ConfigurationService
   • traceId?: string
   • cardHandle?: string - Identifier for the card
   • certRefList?: string[] - Types of certificates (C.AUT, C.QES, C.SIG, C.ENC)
   • crypt?: CryptType - 'RSA' | 'ECC'
   • Returns: Promise<ReadCardCertificateResponseMessage>
   • Defaults: If no certRefList provided, defaults to ['C.AUT']
   • Throws: Error if cardHandle is null/undefined

3. checkCertificateExpiration(configurationService, traceId?, cardHandle?, crypt?) - Purpose: Checks expiration dates of certificates on cards - Parameters: Similar to readCardCertificate - Returns: Promise<CheckCertificateExpirationResponseMessage>

Event Handler Methods:

• handleVerifyCertificateEvent(configurationService, traceId?, certificate?)
• handleReadCardCertificateEvent(configurationService, traceId?, cardHandle?, certRefList?, crypt?)
• handleCheckCertificateExpirationEvent(configurationService, traceId?, cardHandle?, crypt?)

3. OCSP and Revocation Checking Support

Key Finding: CertificateService does NOT directly support OCSP. Instead, OCSP verification is handled separately in VauValidation.verifyCertificateRevocationStatus().

How OCSP Works:

The architecture splits responsibilities:

1. CertificateService - Verifies basic certificate validity (via TI Connector)
2. VauValidation - Handles OCSP-specific revocation checking

OCSP Implementation in VauValidation:

// From vauValidation.ts lines 28-70
verifyCertificateRevocationStatus(
  configurationService,
  encCertificateBuffer,  // The VAU encryption certificate
  ocspResponseBuffer      // OCSP response from VAU
)

OCSP Verification Steps: 1. Parse OCSP response using pkijs library 2. Extract signer certificate from OCSP response 3. Verify OCSP signer certificate using CertificateService.verifyCertificate() 4. Verify OCSP response signature using JWKSignature.verify() 5. Check certificate revocation status in OCSP response

4. Parameters and Return Types

Request Messages:

// VerifyCertificateRequestMessage
{
  Context: ConnectorContext           // Connector context (MandantId, ClientSystemId, etc.)
  X509Certificate: string             // Base64-encoded certificate
  VerificationTime?: Date             // Optional verification timestamp
}

// ReadCardCertificateMessage
{
  CardHandle: string
  Context: ConnectorContext
  CertRefList: { CertRef: CertRefType[] }  // ['C.AUT' | 'C.QES' | 'C.SIG' | 'C.ENC']
  Crypt?: CryptType                        // 'RSA' | 'ECC'
}

// CheckCertificateExpirationRequestMessage
{
  Context: ConnectorContext
  CardHandle?: string
  Crypt?: CryptType
}

Response Messages:

// VerifyCertificateResponseMessage
{
  Status: {
    Result: 'OK' | 'Warning'
    Error?: string
  }
  VerificationStatus: {
    VerificationResult: 'VALID' | 'INCONCLUSIVE' | 'INVALID'
    Error?: Error
  }
}

// ReadCardCertificateResponseMessage
{
  Status: { Result: 'OK' | 'Warning' }
  X509DataInfoList: {
    X509DataInfo: {
      CertRef: 'C.AUT' | 'C.QES' | 'C.SIG' | 'C.ENC'
      X509Data?: {
        X509IssuerSerial: { X509IssuerName, X509SerialNumber }
        X509SubjectName: string
        X509Certificate: base64string
      }
    }[]
  }
}

// CheckCertificateExpirationResponseMessage
{
  Status: { Result: 'OK' | 'Warning' }
  CertificateExpiration: {
    CtID: string
    CardHandle: string
    ICCSN: string
    subject_commonName: string
    serialNumber: string
    validity: Date
  }[]
}

5. TI Connector Interaction

How CertificateService Interacts with TI Connector:

1. SOAP Client Creation - Uses soap library to create async SOAP client - Loads WSDL from: CertificateService_v6_0_1.wsdl - Endpoint resolved from connector service directory

2. SSL/TLS Configuration - Calls addSSLOptionsToSoapClient() for client cert authentication - Uses connector's certificate and private key from ConfigurationService

3. Connector Operations - Calls VerifyCertificateAsync() on connector - Calls ReadCardCertificateAsync() on connector - Calls CheckCertificateExpirationAsync() on connector

4. Context Passing - Every operation includes Context: ConnectorContext with:

   • MandantId - Mandant/Tenant ID
   • ClientSystemId - Client system identifier
   • WorkplaceId - Workplace identifier
   • UserId - User identifier

5. Service Endpoint Management - Supported version: 6.0.1 - Dynamic endpoint resolution from connector's service directory - URL: http://ti-konnektor/certificateservice

Logging Integration

• Uses kbvTiConnectLogger for debug/error logging
• Logs both input parameters and output responses
• Uses extraLogParser utility for structured logging

6. OCSP & Revocation Checking Details

The revocation checking is implemented in VauValidation.verifyCertificateRevocationStatus():

OCSP Verification Signature:

await JWKSignature.verify({
  payload: ocspBasicResp.tbsResponseData.tbsView,           // TBS (to be signed) data
  signatureValue: ocspBasicResp.signature.valueBlock.valueHexView,
  rawSignerCertificate: rawSignerCertificate                // Base64-encoded cert
})

Revocation Status Check:

// Extract certificate serial number and check OCSP response
const certificateSerialNumber = Certificate.fromBER(encCertificateBuffer).serialNumber.toBigInt()

ocspBasicResp.tbsResponseData.responses.forEach((resp) => {
  if (resp.certID.serialNumber.toBigInt() === certificateSerialNumber) {
    const certStatus = resp.certStatus.idBlock.tagNumber as number
    if (certStatus !== 0) {  // 0 = good, non-zero = revoked/suspended
      throw new Error(`Certificate revoked, status: ${certStatus}`)
    }
  }
})

Error Scenarios: - EMPTY_RESPONSE_BYTES_ERROR - OCSP response has no ResponseBytes - Missing signer certificate in OCSP response - No cert to verify signature - OCSP signer certificate is not valid - CertificateService verification failed - Invalid OCSP Response signature - JWKSignature verification failed - VAU certificate is not valid, the certificate status is: {status} - Certificate revoked
