Installing Trusted Certificates on Mobile phone

Now a days, mobile phone has become a part and parcel of our life. We not only call to our friends and relatives using a mobile phone but also send short messages, browse internet and many more. Many of us visit secure website like yahoo, gmail, msn, facebook etc. If your phone is a certificate supported phone, it may show a warning message telling 'Website not certified, continue with a secure connection?' or something like this when you access those secure connection using the default browser of phone. Sometimes that message shows for a several times. Then we need to press the 'Yes' button to allow accessing a secure connection. This is disturbing. On the other hand, during receiving email or synchronizing contacts on our phones' default database we see warning messages like that. This problem can be solved easily by installing some certificate on phone memory, that means, phone's file system.

In this article I'll show you how easily certificates can be installed into phone. To see if your phone is certificate supported or not, go to setting, then scroll to security. Here you’ll find an option named ‘certificates’. Click this option and you’ll see the trusted certificates installed in your phone system. If you don’t find any option like ‘certificate’ or ‘security’ into ‘Settings’, you may find that into ‘internet’. If you can’t find these things into your phone, your phone is not a certificate supported one. Now let’s see how to install certificate into phone.

You need a computer to do this deal. The computer needs to have internet connection and all security of that updated. Trusted certificate can be found in web browser of a computer. Here I’ll show you the process of copying trusted security certificates from Internet Explorer and Mozilla Firefox.

Internet Explorer: On Internet Explorer,

go to ‘Tools>Internet Option>On the middle of the tabs, click ‘Content’>On the middle of the window, click ‘Certificates’. Here you’ll see six tabs named

1. Personal

2. Other People

3. Intermediate Certification Authorities

4. Trusted Root Certification Authorities

5. Trusted Publishers

6. Untrusted Publishers

Click these tabs and you’ll see the trusted certificates. Now you need to copy the certificate into file. To do it,

double click on any of the certificates.

Then click details. Before copying to file check that the certificate is expired or not from the ‘General’ tab. On the bottom of the window, click ‘copy to file’. Continuously click ‘Next’ until the name field appear. Now give a name any of your choice and save that with (.cer) extension. That’s all.

Mozilla Firefox:

On Mozilla Firefox, click ‘Tools>Option>click the last tab, ‘Advanced’>click ‘view certificates’. Here you’ll find five tabs those contains the trusted certificates. Click any of the certificate you as your need and then click ‘Export’. Now give the file name with (.cer) extension and make the file type ‘All files’ and then save.

Installing on phone: You may install a certificate in several ways. Just copy the file to memory card or phone memory. This time the certificates can be shown as unsupported item on phone. Now send the certificates to the phone where you need to install the certificates via bluetooth or infrared. This is the easiest way to install certificate on phone. After installing a certificate on phone some phone restarts or some phone ask for continuation of installing the certificate without restart. Now you have necessary certificates on your phone and from then the warning message will not show while browsing secure networks.

N.B: Certificates from mozilla firefox may not support on most of the phones as the certificates on mozilla firefox are of (.pem) extension. But most of the phones supports certificates of (.cer) extension
