Owners of Nokia phones often ask a question about how to sign an application. This is necessary in cases where the SIS file was downloaded to the smartphone, and when you try to install it, a certificate error message appears . 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 desired application with your certificate, which is issued for a specific IMEI, you can install it.
Before signing a certificate, you need to know a little about it. It is a document in electronic form, which gives rights to certain applications to be installed in the Symbian 9.x environment for a specific user. He makes requirements for software developers, depending on how the operating systems, as well as Nokia hardware , are developing. It is these factors that will affect the determination of the term and conditions of use of the certificate issued by Symbian.
So, before signing the application, you must order a certificate. To do this, go to the Nokia Club website and enter there fifteen digits of the IMEI code of your phone, which you can find out by dialing * # 06 #. After 13-36 hours, visit the site again and re-enter. If you are informed that he is not ready yet, you will need to wait a few more hours.
Now let's move on to how to sign the application. For this purpose I use the SisSigner program. As soon as you receive your certificate, this software will easily sign the application of interest for you to install on your device. So, download the installation file for this software and install it on your computer. After this procedure, you will need to add your certificate and archive key to the Cert program folder (downloaded with the program for subscription).
When you complete all these steps, you will have at your disposal a personal certificate, its key, as well as the installed program for signing. We proceed directly to the signing procedure of our application. We go into the program directory and copy the certificate received on the site there. Please note that its extension must be CER. Also, copy the key to the certificate to this directory, its extension is KEY. And finally, add the phone application that you want to sign to these files.
After that, we run the program and specify the path for our key, certificate and 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, after which a request for confirmation of this action will appear. Press the button to confirm.
If you did everything correctly, the application becomes signed. You can safely install it in your smartphone. To do this, connect the device to the computer and install the program on the phone using the special Nokia software. That is the whole procedure.
