Nit: this blank line is not necessary.

[markusheintz_, 2012/02/15 19:04:18]

Done.

+// The |WebsiteSettingsModel| provides information about the connection and the
+// identity of a website. The |WebsiteSettingsModel| is the backend for the
+// WebsiteSettingsUI which displays this information.

[wtc, 2012/02/15 02:14:29]

Nit: I don't know why you named this class WebsiteSettingsModel.
"Settings" implies configuration or preferences, but
this class contains information.

[markusheintz_, 2012/02/15 19:04:18]

This will become more than just a data model. Originally I named it
"WebsiteSettings" and I plan to return to this name.
I will provide you more details via email.

+class WebsiteSettingsModel {
+ public:
+  // Status of a connection to a website.
+  enum SiteConnectionStatus {
+    SITE_CONNECTION_STATUS_NA = 0,           // No status available.

[wtc, 2012/02/15 02:14:29]

Nit: "N/A" stands for "not applicable" as opposed to
"not available".  I suggest you use _NONE or
_UNKNOWN.

This comment also applies to SITE_IDENTITY_STATUS_NA on
line 37 below.

[markusheintz_, 2012/02/15 19:04:18]

Done.

+    SITE_CONNECTION_STATUS_ENCRYPTED,        // Connection is encrypted.
+    SITE_CONNECTION_STATUS_MIXED_CONTENT,    // Site has unencrypted content.
+    SITE_CONNECTION_STATUS_UNENCRYPTED,      // Connection is not encrypted.
+    SITE_CONNECTION_STATUS_ENCRYPTED_ERROR,  // Connection error occured.
+    SITE_CONNECTION_STATUS_INTERNAL_PAGE,    // Internal site.

[wtc, 2012/02/15 02:14:29]

I don't know what "Internal" means here.  Internal to a
company, or internal to Chrome?

[markusheintz_, 2012/02/15 19:04:18]

Internal to chrome. Internal pages like chrome://settings, chrome://ABC

+  };
+
+  // Validation status of a website's identity.
+  enum SiteIdentityStatus {
+    // No status about the website's identity available.
+    SITE_IDENTITY_STATUS_NA = 0,

+    SITE_IDENTITY_STATUS_CERT,
+    // The website provided a valid EV certificate.
+    SITE_IDENTITY_STATUS_EV_CERT,
+    // The website provided a valid DnsSec certificate.

[wtc, 2012/02/15 02:14:29]

Nit: DnsSec => DNSSEC

[markusheintz_, 2012/02/15 19:04:18]

Done.

+    SITE_IDENTITY_STATUS_DNSSEC_CERT,
+    // The website provided a valid certificate but no revocation check could be
+    // performed.
+    SITE_IDENTITY_STATUS_CERT_NOT_VERIFIED,

[wtc, 2012/02/15 02:14:29]

Change "NOT_VERIFIED" to "REVOKE_STATUS_UNKNOWN"
or "REVOCATION_UNKNOWN".

[markusheintz_, 2012/02/15 19:04:18]

Done. I chose REVOCATION_UNKNOWN.

[wtc, 2012/02/15 02:14:29]

Nit: a EV => an EV

[markusheintz_, 2012/02/15 19:04:18]

Done.
