26 A B<CT_POLICY_EVAL_CTX> is used by functions that evaluate whether Signed
27 Certificate Timestamps (SCTs) fulfil a Certificate Transparency (CT) policy.
28 This policy may be, for example, that at least one valid SCT is available. To
29 determine this, an SCT's signature must be verified. This requires:
33 =item * the public key of the log that issued the SCT
35 =item * the certificate that the SCT was issued for
37 =item * the issuer certificate (if the SCT was issued for a pre-certificate)
41 The above requirements are met using the setters described below.
43 CT_POLICY_EVAL_CTX_new() creates an empty policy evaluation context. This
44 should then be populated using:
48 =item * CT_POLICY_EVAL_CTX_set1_cert() to provide the certificate the SCTs were issued for
50 Increments the reference count of the certificate.
52 =item * CT_POLICY_EVAL_CTX_set1_issuer() to provide the issuer certificate
54 Increments the reference count of the certificate.
56 =item * CT_POLICY_EVAL_CTX_set_shared_CTLOG_STORE() to provide a list of logs that are trusted as sources of SCTs
58 Holds a pointer to the CTLOG_STORE, so the CTLOG_STORE must outlive the
63 Each setter has a matching getter for accessing the current value.
65 When no longer required, the B<CT_POLICY_EVAL_CTX> should be passed to
66 CT_POLICY_EVAL_CTX_free() to delete it.
70 The issuer certificate only needs to be provided if at least one of the SCTs
71 was issued for a pre-certificate. This will be the case for SCTs embedded in a
72 certificate (i.e. those in an X.509 extension), but may not be the case for SCTs
73 found in the TLS SCT extension or OCSP response.
77 CT_POLICY_EVAL_CTX_new() will return NULL if malloc fails.
