Go online to a SymbianSigned account to generate a new developer's certficate for SIS files.
"SIS" is a type of file format used for installable applications on the Symbian operating system. The Symbian operating system is used by some smartphone devices, such as the Nokia E7. To install a SIS file onto a Symbian-based mobile device, the SIS application has to be "signed." This signature is a security measure of sorts. It's what authenticates the application, providing assurances that the application is not malware or a virus. If a SIS application is not signed by its developer, users can acquire their own Developer's Certificate to sign the application themselves.
Instructions
Update a Symbian Developer's Certificate
1. Go to the SymbianSigned website (see the link in the Resources section) and sign into your user account.
2. Click on the "My Symbian Signed" tab. Select "Developer Certificate" in the menu options. Click "Request." You have to request a new Developer Certificate because once one has expired it cannot be renewed. You will need to be issued a new one.
3. Upload the original .crs (certificate request) file you created when you generated the original Developer's Certificate. If the original .crs file is no longer saved on your computer, you can download the file again from the user account area of the SymbianSigned interface. After downloading and saving the file to your computer, navigate back to the "Request" portal on the SymbianSigned interface and upload the file.
4. Follow the on-screen prompts to generate a new Developer's Certificate. This newly generated Developer's Certificate can be downloaded anytime by logging into your SymbianSigned account. Go to the "My Symbian Signed" tab. Select "Developer Certificate" in the menu options. Click "MyDevCerts" and download the certificate.
