How to sign an application for Nokia smartphones?

Owners of Nokia phones often ask a question about how to sign the application? This is necessary when the SIS file was downloaded to the smartphone, and when you try to install it, you receive a certificate error message. To solve this problem, you need to sign a certificate. What does this mean? Developers thus prevent the use of pirated software. But if you can sign the required application with your certificate, which is issued for a particular IMEI, you can install it.

Before signing the certificate, you need to learn a little about it. It is a document in electronic form, which entitles one or another application to be installed on a Symbian 9.x environment for a specific user. He makes demands on the developers of software, depending on how the operating systems develop, as well as the hardware at Nokia. It is these factors that will influence the determination of the terms and conditions for the use of the certificate, which is issued by Simbian.

So, before you sign the application, you must order a certificate. To do this, go to the site of Nokia's club and enter there fifteen digits of your phone's IMEI code, you can find out by dialing * # 06 #. After 13-36 hours, go to the site again and try again. If you are told that he is not ready yet, you will need to wait a few more hours.

But now we move on to how to sign the application. For this purpose I use the SisSigner program. Once you receive your certificate, this software will easily sign the application you are interested in for installation on your device. So, download the installation file of this software and install it on your computer. After this procedure, you will need to add your certificate and the archive key to the Cert program folder (downloaded together with the subscription program).

When all these actions you perform, at your disposal will be a personal certificate, its key, and also the installed program for signing. We proceed directly to the signature procedure of our application. We go to the program directory and copy there the certificate received on the site. Please note that its extension must be CER. Also in this directory copy the key to the certificate, its extension is KEY. And finally, we add to these files the application for the phone that you want to sign.

After that, we run the program and specify the path for our key, certificate and the application to be signed. You can not rename these files, the most important thing is to specify the correct path. After that, click on the "Sign" button, and you will be asked to confirm this action. Press the button to confirm.
