Did you ever wonder why does the applications like opera mini (in 90% cases) asks for a permission while connecting to the network or while reading or writing on your phone's memory????????????? i.e. something an error like this----ALLOW THIS APPLICATION TO CONNECT TO NETWORK.
Most of us would answer NO in that case. But I am going to tell you a characterstic reason for that.
The easiest reason for the fact is that these applications are not digitally signed. Confused?????????? Ok let me explain what digital signatures are:
A digital signature or digital signature scheme is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, and that it was not altered in transit. Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering.
The applications which we download through the phone manufacturer's official website like in case of Nokia THE OVI STORE, you always download a digitally signed application. But whenever the talk begins of a third party apps let me tell you those apps are never digitally signed. Ever heared about VERISIGN ? Or Thawte? Actually these are organisations which develop these digital signatures for mobile phones. These signatures are just to authenticate that no application can harm your digital device.
You might be wondering that opera is a trusted brand , then why do they themselves not give digitally signed application i.e. OPERA MINI. The answer is they do give digitally signed opera mini but their homepage provide an unsigned version. Don't worry I will explaining how to download a signed version of opera mini. Just follow these simple steps:
1. Go to Opera mini website with your phone's browser.
2. Now you might be seeing suggested downloads for your phone. Just ignore them and click on the link OTHER DOWNLOAD OPTIONS.
3. Now browse to the bottom and you will see a heading " OTHER OPTIONS FOR OPERA MINI 6.5 "(an example in our case).
4. Under that head there is a link provided saying SELECT CODE SIGNING CERTIFICATE.Click on that.
5.A new page opens up which might say AUTO DETECTION OF CODE SIGNING CERTIFICATE FAILED. No worries select a suitable certificate from the list of certificates given below. I would recommend selecting ALL CERTIFICATES as the certificates may vary from phone to phone.
6. Again a new page pops up asking for you to download OPERA MINI 6.5. Go ahead and click this link. Actually this is a digitally signed link.
7. You are ready to go once the application downloads.
8. Now to change the access permissions in your NOKIA phone goto the downloaded location. Open OPTIONS> APPLICATION ACCESS> COMMUNICATION>NETWORK ACCESS AND CHANGE IT TO ALWAYS ALLOWED.
9. You are ready to go. Now everytime you access internet with your application are need not give permissions your connecting to the network.
10. Please note that if you would have downloaded the unsigned application from the opera mini home page you will not be able to change the access permissions to always allowed.
Please comment if you like my post . Any suggestions are gratefully admired.
