无声安装PFX到Andorid系统可信CA用户密钥库

Question

我的公司正在开发使用android平板电脑的自助服务终端。我们正在使用TLS与私人服务器进行通信。我们有平台键给我们的客户端应用程序系统权限。如果使用授权客户端证书进行连接，服务器将只允许客户端进行连接。为了制造平板电脑，我们需要将PFX格式的客户端证书和私钥加载到Android系统可信CA用户密钥库中。多个应用程序需要从用户密钥库中检索PrivateKey和Certificate链。我们的制造流程是一个自动化流程，没有人员点击是和确定屏幕提示。我们还需要静默证书安装过程来替换未来客户端证书过期的客户端证书。

如何将PFX文件从平台签名应用程序中静默装入系统可信CA用户存储，无需用户交互？

这仅适用于企业WiFi配置。以下方法将使用CA证书和用户证书配置WPA/EAP-TLS wifi配置。

 
public static void createEapConfig(Context context, String ssid, String password, boolean connectAutomatically, boolean hiddenNetwork, 
            Integer eapMethod, Integer phase2, String identity, String anonymousIdentity, String caCertificateData, 
            String clientCertificateData, String clientCertPass) { 
    if (ssid == null || eapMethod == null) { 
     return; 
    } 
    WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); 
    boolean connect = connectAutomatically; 
    boolean isWifiReceiverRegistered = false; 
    try { 
     Logger.logEnteringOld(); 

     WifiConfiguration config = new WifiConfiguration(); 
     config.SSID = "\"" + ssid + "\""; 
     config.hiddenSSID = hiddenNetwork;//false; //hidden network is always set to false. 
     config.status = WifiConfiguration.Status.ENABLED; 
     config.priority = 40; 
     try { 
      wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class).invoke(wifiManager, config, false); 
     } catch (Exception e) { 
      Logger.logError(e); 
     } 
     Settings.isWifiHotspotEnabled(false); 
     if (!wifiManager.isWifiEnabled()) { 
      wifiManager.setWifiEnabled(true); 
      Thread.sleep(5000); 
     } 

     if (connect) { 
      lastActNetId = wifiManager.getConnectionInfo().getNetworkId(); 
      wifiManager.disableNetwork(lastActNetId); 
      wifiManager.disconnect(); 
     } 
     config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
