A CT_POLICY_EVAL_CTX must be provided that specifies:
Failure to provide the certificate will result in the validation status being SCT_VALIDATION_STATUS_UNVERIFIED.
This is only required if the SCT was issued for a pre-certificate (see RFC 6962). If it is required but not provided, the validation status will be SCT_VALIDATION_STATUS_UNVERIFIED.
If the SCT was issued by a log that is not in this CTLOG_STORE, the validation status will be SCT_VALIDATION_STATUS_UNKNOWN_LOG.
If the SCT is of an unsupported version (only v1 is currently supported), the validation status will be SCT_VALIDATION_STATUS_UNKNOWN_VERSION.
If the SCT's signature is incorrect, its timestamp is in the future (relative to the time in CT_POLICY_EVAL_CTX), or if it is otherwise invalid, the validation status will be SCT_VALIDATION_STATUS_INVALID.
If all checks pass, the validation status will be SCT_VALIDATION_STATUS_VALID.
SCT_LIST_validate() returns a negative integer if an internal error occurs, 0 if any of SCTs fails validation, or 1 if they all pass validation.
SCT_get_validation_status() returns the validation status of the SCT. If SCT_validate() or SCT_LIST_validate() have not been passed that SCT, the returned value will be SCT_VALIDATION_STATUS_NOT_SET.
