+// Inputs
+// ---------
+//
+//   cert_chain:
+//     A non-empty chain of N DER-encoded certificates, listed in the
+//     "forward" direction.
+//
+//      * cert_chain[0] is the target certificate to verify.
+//      * cert_chain[i+1] holds the certificate that issued cert_chain[i].
+//      * cert_chain[N-1] must have been issued by a trusted root.
+//
+//   trust_store:
+//     Contains the set of public keys that are trusted as roots.
+//
+//   signature_policy:
+//     The policy to use when verifying signature (what hash algorithms are
+//     allowed, what length keys, what named curves, etc).
+//
+//   time:
+//     The UTC time to use for expiration checks.
+//
+//
+// ---------
+// Outputs
+// ---------
+//
+//   returns true if the target certificate can be verified.
