BUG (inefficiency): we already have the cert chain in
|completed_chain|.  See line 789 above.  So we should pass
completed_chain instead of cert_handle_ to IsRootedAtKnownRoot.

Move this static function into the unnamed namespace above
at lines 34-497.

[agl, 2011/04/06 19:02:02]

It's no longer static because IsSHA1HashInSortedArray is now private. Also, it
has to be after the array of hashes. So I've moved the array into a header file.

+  CFArrayRef cert_chain = NULL;
+  OSStatus result;
+  result = CopyCertChain(cert_ref, &cert_chain);
+  if (result)
+    return false;
+  ScopedCFTypeRef<CFArrayRef> scoped_cert_chain(cert_chain);
+
+  int n = CFArrayGetCount(cert_chain);
+  if (n < 1)
+    return false;
+  SecCertificateRef root_ref = reinterpret_cast<SecCertificateRef>(
+      const_cast<void*>(CFArrayGetValueAtIndex(cert_chain, n - 1)));
+  CSSM_DATA der_bytes;
+  result = SecCertificateGetData(root_ref, &der_bytes);
+  if (result)
+    return false;
+  uint8 hash[base::SHA1_LENGTH];
+  base::SHA1HashBytes(der_bytes.Data, der_bytes.Length, hash);

[wtc, 2011/04/06 04:28:38]

You can use the CalculateFingerprint static method.

Done.
