How do I sign an application with a certificate?

Sometimes, buying a novelty, namely a new smartphone,We can face problems that are often associated with the installation of games and applications. Let's look at how to make the application signature a certificate. For this we need a personal computer, a mobile phone with Symbian OS and a USB cable.

Signing via SISSigner

A step-by-step algorithm for signing an application with a certificate:

Download the archive "SISSigner" and additionalprograms. Download the archive with the program here. In the folder "cert" there is a file "mykey". This file must be replaced with the installation file "SISSigner". You must first install the program "SISSigner" and only then replace the file "cert" and an additional archive. A personal signature certificate can be obtained here.
Now go to the application signature. We do this with the help of the same program "SISSigner". To do this, open the folder with the program and copy the certificate (called "cer") and the resulting key (called "key"). Now these files are inserted into the folder with the application or game for your smartphone, which needs a signature.
Now start "SISSigner", indicating the path in itto the necessary files: to the certificate "cer" and to the key "key". The password for the "key" file is standard - 12345678. These key and certificate files do not need to be renamed, the main thing is that the "SISSigner" has the correct path to them. It remains only to click the "Sign" button and download the application to your phone.

Signing via SignSIS

You can also use another application, you can download it here.

We need to download and extract the archive. There we will see four files: "signsis.exe", "uninstall.bat", "install2.bat", "install1.bat". They need to be copied to the same location as the signature certificate and the key. Now replace the names: the certificate is replaced with "cert.cer", and the key is replaced with "cert.key". Then you need to open the file "install1.bat" with notepad and change the "set password1" parameter to another, invented password, the standard password is always 12345678.
Change the path to the folder with the program in the "set"app_path2 "and" set disk_ins ". That is, for example, the program is on disk D: Nokia6290sign_sis, then you need to replace the value with set disk_ins = D: set app_path = Nokia / 6290 / sign_sis. Now we save everything in the notebook.
If you did everything right, then when you startfile "install1.bat" you will see the inscription "Sign a personal certificate". You only need to select an application that needs a signature and click on this label. After the end of the signature, next to the source file appears signed, in its name will be added the word "signed".

Now let's look at how to sign the application with a certificate on the computer. There are several ways.

Using the program "SISSigner". Download it and install it. In its folder we add the certificate of the signature key, the file "cert". Now we have a personal certificate and a key, and only need to make the application signature. To do this, go to the folder with the program "SISSigner", we copy the certificate of electronic signature, with permission cer, the key to the certificate, with the permission key, and the application that needs a subscription. By running the "SISSigner" file and specifying the path to the key key received when it was ordered, the path to the application you want to sign, and the path to the certificate, also received when ordering, the password key. Now we press the button to sign everything.
We sign the application with Signsis. There are advantages here, you do not need to work with the command line and you do not need to enter paths into the program window. In addition, you can sign any application located on the hard drive, no matter which folder.
