关于Chrome 17/18/19 EV SSL证书(绿色地址栏)乱码问题

  最近升级Chrome(谷歌浏览器)到目前最新稳定版本17.0.963.46 m,结果通过HTTPS访问使用了SSL EV证书(非英文)的网站时“绿色地址栏”出现了乱码! 目前国内各大银行虽然也有通过SSL EV证书的绿色地址栏提高网站安全性,很直观的向来访者展示网站身份,防止钓鱼网站;但是都爱走国际路线--基本上都是英文名称,这样却不方便国内网民去识别其身份,不过这次他们幸运的逃过了此劫...

  通过Chrome的“工具” -> “报告问题” 提交问题后,也不知道提交到哪了(问题列表中也没看到http://code.google.com/p/chromium/issues/list)。

    Check out Chrome的源码查看UI部分的toolbar代码也没发现什么问题,想估计是证书信息解析方面问题了...

    http://src.chromium.org/svn/trunk/src/chrome/browser/ui/toolbar/toolbar_model.cc

    string16 ToolbarModel::GetEVCertName() const {
    
      DCHECK_EQ(GetSecurityLevel(), EV_SECURE);
    
      scoped_refptr cert;
    
      // Note: Navigation controller and active entry are guaranteed non-NULL or
    
      // the security level would be NONE.
    
      CertStore::GetInstance()->RetrieveCert(
    
          GetNavigationController()->GetVisibleEntry()->GetSSL().cert_id, &cert);
    
      return GetEVCertName(*cert);
    
    }
    
    
    
    // static
    
    string16 ToolbarModel::GetEVCertName(const net::X509Certificate& cert) {
    
      // EV are required to have an organization name and country.
    
      if (cert.subject().organization_names.empty() ||
    
          cert.subject().country_name.empty()) {
    
        NOTREACHED();
    
        return string16();
    
      }
    
    
    
      return l10n_util::GetStringFUTF16(
    
          IDS_SECURE_CONNECTION_EV,
    
          UTF8ToUTF16(cert.subject().organization_names[0]),
    
          UTF8ToUTF16(cert.subject().country_name));
    
    }

    今天再去问题列表中查看,发现也有人提交了相同的问题(http://code.google.com/p/chromium/issues/detail?id=114168)。

    这次确定问题大概是 http://codereview.chromium.org/9358080/diff/1/net/base/x509_certificate_win.cc 中的 GetAttributeValue函数使用了 CertRDNValueToStrA导致的!

    // Converts the value for |attribute| to an ASCII string, storing the result	
    
    // in |value|. Returns false if the string cannot be converted.	
    
    bool GetAttributeValue(PCERT_RDN_ATTR attribute,	
    
                           std::string* value) {	
    
      DWORD bytes_needed = CertRDNValueToStrA(attribute->dwValueType,	
    
                                              &attribute->Value, NULL, 0);	
    
      if (bytes_needed == 0)	
    
        return false;	
    
      if (bytes_needed == 1) {	
    
        // The value is actually an empty string (bytes_needed includes a single	
    
        // byte for a NULL value). Don't bother converting - just clear the	
    
        // string.	
    
        value->clear();	
    
        return true;	
    
      }	
    
      DWORD bytes_written = CertRDNValueToStrA(	
    
          attribute->dwValueType, &attribute->Value,	
    
          WriteInto(value, bytes_needed), bytes_needed);	
    
      if (bytes_written

    问题出现在这次的修改:http://src.chromium.org/viewvc/chrome/trunk/src/net/base/x509_certificate_win.cc?r1=112005&r2=112650

相关补丁

  主要修复:

// Converts the value for |attribute| to an UTF-8 string, storing the result

// in |value|. Returns false if the string cannot be converted.

bool GetAttributeValue(PCERT_RDN_ATTR attribute,

                       std::string* value) {

  DWORD chars_needed = CertRDNValueToStrW(attribute->dwValueType,

                                          &attribute->Value, NULL, 0);

  if (chars_needed == 0)

    return false;

  if (chars_needed == 1) {

    // The value is actually an empty string (chars_needed includes a single

    // char for a NULL value). Don't bother converting - just clear the

    // string.

    value->clear();

    return true;

  }

  std::wstring wide_name;

  DWORD chars_written = CertRDNValueToStrW(

      attribute->dwValueType, &attribute->Value,

      WriteInto(&wide_name, chars_needed), chars_needed);
