DESCRIPTION

A CT_POLICY_EVAL_CTX is used by functions that evaluate whether Signed Certificate Timestamps (SCTs) fulfil a Certificate Transparency (CT) policy. This policy may be, for example, that at least one valid SCT is available. To determine this, an SCT's timestamp and signature must be verified. This requires:

The above requirements are met using the setters described below.

CT_POLICY_EVAL_CTX_new() creates an empty policy evaluation context. This should then be populated using:

Each setter has a matching getter for accessing the current value.

When no longer required, the CT_POLICY_EVAL_CTX should be passed to CT_POLICY_EVAL_CTX_free() to delete it.

NOTES

The issuer certificate only needs to be provided if at least one of the SCTs was issued for a pre-certificate. This will be the case for SCTs embedded in a certificate (i.e. those in an X.509 extension), but may not be the case for SCTs found in the TLS SCT extension or OCSP response.

RETURN VALUES

CT_POLICY_EVAL_CTX_new() will return NULL if malloc fails.
