Signing Symbian/Qt Application in Linux

Signing Symbian/Qt Mobile Applications conventionally has to be done on Windows.
The good news is now it's possible to sign Symbian/Qt mobile applications in Linux-based operating systems such as Ubuntu, with the help of wine.

  1. First you need to get a Symbian certificate and key.
    You can get your applications Symbian signed for free and get developer certificates from Ovi Publish.

  2. Extract the signsis.exe file from this zip file.
    Source: FExplorer thread
    I recommend to make this file executable so you can run it directly with Wine and not having to prefix "wine" command for launching.
    Running this command on Terminal:
    chmod +x signsis.exe

  3. Install Wine.
    In Ubuntu, open Terminal and type:
    sudo apt-get install wine
Now you can sign your unsigned SIS application files.

Type this command in Terminal:

wine path/to/signsis.exe <application-file.sis> <certificate.crt> <certificate.key>

If you make signsis.exe executable you can simply type:

wine path/to/signsis.exe <application-file.sis> <certificate.crt> <certificate.key>

Now you can sign any SIS file at will. :-)

For example in my system this is how it looks:

$ /opt/signsis/signsis.exe -s -v messagemerge_qt-4_6_3_m1_0_2_s60_3_1.sis messagemerge_devsigned.sis OVI_10-29-2010.crt OVI_10-29-2010.key
