authorized any responder issued by an ancestor of the target's issuer;
RFC 6960 4.2.2.2 requires direct issuance by the CA identified in the
request.
- Remove CheckOcspResponderChain() and WOLFSSL_NO_OCSP_ISSUER_CHAIN_CHECK.
- Drop now-unused vp parameter from CheckOcspResponder() and the
OcspRespCheck() helper; cascade through template and non-template
paths.
OCSP test blobs:
- Re-sign resp_server1_cert with intermediate1-ca (CA-direct path).
- Add resp_server1_cert_ancestor_responder for the negative test.
- Embed server1_cert_pem[] in test_ocsp_test_blobs.h so the new test
runs under NO_FILESYSTEM; matching entry added to
create_ocsp_test_blobs.py.
- Regenerate response[] in test_certman.c with intermediate1-ca as
signer; recipe switched from Wireshark export to openssl -respout
+ xxd -i for reproducibility.
- Fix self-XOR in test_wolfSSL_CertManagerCheckOCSPResponse so the
serial byte actually flips (^= 0xFF).
Live OCSP coverage:
- Add ocsp-responder-int1 (delegated responder issued directly by
intermediate1-ca, with id-kp-OCSPSigning EKU) for the
responder->intermediate->root chain.
- scripts/ocsp-stapling.test: intermediate1 responder switched to
ocsp-responder-int1 (delegated path).
- scripts/ocsp-stapling2.test, scripts/ocsp-stapling_tls13multi.test:
intermediate2 and intermediate3 sign their OCSP responses with
their own CA keys (CA-direct path); root block unchanged
(ocsp-responder-cert is still RFC-compliant for root-issued certs).
- .github/workflows/ocsp.yml: server1 OCSP responder switched to
ocsp-responder-int1 to match the cert chain.
- New test_ocsp_ancestor_responder_rejected confirms the
ancestor-issued response is rejected with OCSP_LOOKUP_FAIL.
Adds resp_certid_keyhash_mismatch — a forged response signed by the
legitimate ocsp-responder whose CertID pairs the legitimate root CA's
issuerNameHash with the imposter root CA's issuerKeyHash. The new
test_ocsp_responder_keyhash_binding asserts wolfSSL_OCSP_basic_verify
rejects it, exercising the fix that requires both halves of the
CertID to match the responder's issuer.
Exposes dynamic TLS certificate loading and OCSP stapling to allow applications to load certs lazily.
The server no longer needs to load the CA to staple OCSP responses.
Adds a certificate setup callback (WOLFSSL_CERT_SETUP_CB)
Adds an OCSP status callback to load OCSP responses directly
Adds `wc_NewOCSP`, `wc_FreeOCSP`, and `wc_CheckCertOcspResponse`
Don't call verify twice on the same error
Send correct alert on status response error
- Added a new test case `resp_bad_embedded_cert` in
`create_ocsp_test_blobs.py` to test OCSP response with an unusable
internal cert that can be verified in Cert Manager.
- Updated `test_ocsp_response_parsing` in `ocsp.c` to include the new
test case.
- Ensured the new test case checks for proper handling of OCSP responses
with incorrect internal certificates.
