Search for any OCSP-related endpoints in the codebase. The Gematik documentation mentions: 1. The deprecated endpoint: /VAUCertificateOCSPResponse (we know this one) 2. A recommended endpoint: /OCSPResponse (need to find this)

Please search for: - Any references to "OCSPResponse" endpoint (not the class/type, but the HTTP endpoint) - TI environment configuration files that might list available endpoints - Connector WSDL files that might define OCSP operations - Any service that might call /OCSPResponse - Check gematik-ti-environment, kbv-ti-connect, and gematik-idp-vau modules

I need to understand: 1. Does this /OCSPResponse endpoint exist in our codebase? 2. Where is it defined? 3. How should it be called? 4. Is it part of the VAU service or the TI Connector service?

I'll search for OCSP-related endpoints in the codebase, focusing on the /OCSPResponse endpoint and related TI infrastructure.

Perfect! I now have comprehensive information about OCSP endpoints in the codebase. Let me compile my findings.

Summary of OCSP Endpoints in the Codebase

Based on my thorough search, here are the findings:

1. The `/OCSPResponse` Endpoint - DOES NOT EXIST

The /OCSPResponse endpoint you're looking for does not exist in the codebase. According to the official Gematik documentation referenced in the code, it appears the recommended approach has changed.

2. The Deprecated Endpoint: `/VAUCertificateOCSPResponse`

The codebase currently has the deprecated endpoint implemented:

Location: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/gematik-idp-vau/services/vauClient.ts

public static async fetchOCSPResponse(headerValues?: HeaderValues): Promise<Buffer> {
  const tiEnvProvider = new TiEnvProvider()
  const vauEnv = tiEnvProvider.getEnv('vau')
  const ocspResponse = await fetch(`${vauEnv.hostUrl}/VAUCertificateOCSPResponse`, {
    headers: new Headers(headerValues),
  })
  if (!ocspResponse.ok) {
    throw new Error(`${VAU_OCSP_REQUEST_ERROR} ${ocspResponse.status} ${ocspResponse.statusText}`)
  }
  return ocspResponse.buffer()
}

3. Current Status: OCSP Check Disabled

Location: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/gematik-idp-vau/services/vauService.ts

The OCSP check is currently commented out and disabled:

// https://doctolib.atlassian.net/browse/FHIR-1818
// https://github.com/gematik/api-erp/blob/master/docs/authentisieren.adoc#verbindungsaufbau-zum-e-rezept-fachdienst
// The call to /VAUCertificateOCSPResponse is deprecated, it is recommended to check VAU certificate
// using TI Connector instead
// Commenting the OCSP check now and it will be elaborated in the next ticket.
// const ocspResponse = await VauClient.fetchOCSPResponse(headerValues)

await VauValidation.verifyCertificate(configurationService, encCertificateResponse)
// await VauValidation.verifyCertificateRevocationStatus(configurationService, encCertificateResponse, ocspResponse)

4. The Recommended Approach: TI Connector's `VerifyCertificate` Operation

Instead of a separate /OCSPResponse endpoint, the recommended approach is to use the TI Connector's Certificate Service.

Location: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/kbv-ti-connect/services/certificate-service/soap-client.ts

The TI Connector CertificateService (SOAP-based) currently exposes these operations: - VerifyCertificate - Verifies X.509 certificates using TI Connector - ReadCardCertificate - Reads certificates from the card - CheckCertificateExpiration - Checks certificate validity periods

The VerifyCertificate operation internally handles OCSP/CRL checks as part of the certification validation process, as documented in the WSDL:

Location: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/kbv-ti-connect/services/connector-wsdls/conn/CertificateService_v6_0_1.wsdl

5. Implementation Details

The VAU certificate validation uses the TI Connector's VerifyCertificate operation:

Location: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/modules/gematik-idp-vau/services/vauValidation.ts

public static async verifyCertificate(
  configurationService: ConfigurationService,
  encCertificateBuffer: X509Serialization,
): Promise<void> {
  const verifyCertificateResponse = await CertificateService.verifyCertificate(
    configurationService,
    'unknown',
    encCertificateBuffer.toString('base64'),
  )
  if (verifyCertificateResponse.Status.Result !== 'OK') {
    throw new Error(VAU_ENCRYPTION_CERTIFICATE_INVALID_ERROR)
  }
}

6. Key Architecture Points

VAU Service: Part of gematik-idp-vau module - REST-based endpoints (/VAUCertificate, /VAUCertificateOCSPResponse, /VAU/{userPseudonym})
TI Connector: Part of kbv-ti-connect module - SOAP-based service (CertificateService)
OCSP Verification: Now delegated to TI Connector's built-in certificate verification which checks revocation status using OCSP/CRL

See JIRA ticket: FHIR-1818

Answer to Your Questions:

Does /OCSPResponse endpoint exist? - No, it does not exist in the codebase.
Where is OCSP defined? - It's integrated into the TI Connector's VerifyCertificate SOAP operation, which internally validates certificates including revocation status.
How should it be called? - Through CertificateService.verifyCertificate() which is a SOAP operation, not a REST endpoint.
Is it part of VAU or TI Connector? - The actual OCSP checking is now part of the TI Connector's CertificateService, not the VAU service. The VAU service delegates certificate verification to the TI Connector.
