19 gnutls_x509_trust_list_t trustlist
20 trust anchors as a gnutls_x509_trust_list_t type
21
22 unsigned int * verify
23 output variable with verification status, an
24 gnutls_ocsp_verify_reason_t
25
26 unsigned int flags
27 verification flags from gnutls_certificate_verify_flags
28
30 Verify signature of the Basic OCSP Response against the public key in
31 the certificate of a trusted signer. The trustlist should be popu‐
32 lated with trust anchors. The function will extract the signer cer‐
33 tificate from the Basic OCSP Response and will verify it against the
34 trustlist . A trusted signer is a certificate that is either in
35 trustlist , or it is signed directly by a certificate in
36 trustlist and has the id-ad-ocspSigning Extended Key Usage bit set.
37
38 The output verify variable will hold verification status codes (e.g.,
39 GNUTLS_OCSP_VERIFY_SIGNER_NOT_FOUND, GNUTLS_OCSP_VERIFY_INSECURE_ALGO‐
40 RITHM) which are only valid if the function returned GNUTLS_E_SUCCESS.
41
42 Note that the function returns GNUTLS_E_SUCCESS even when verification
43 failed. The caller must always inspect the verify variable to find
44 out the verification status.
45
46 The flags variable should be 0 for now.
47
49 On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er‐
50 ror value.
