Signing applications with a personal certificate is standard for Nokia smartphones. There is a fairly large selection of programs designed to perform this procedure, differing only in design. In this case, the SignTool program is considered.
Necessary
- - SignTool;
- - personal certificate
Instructions
Step 1
Download the SignTool program archive, available for free download on the Internet, and unpack it into an arbitrary desktop folder to initiate the procedure for signing the selected application with a personal certificate.
Step 2
Run the executable file of the program and click the "Add" button in the "SIS files" section to define the application to be signed.
Step 3
Specify the selected application in the explorer window that opens and click the "Add" button in the "Keys and Certificates" section to define the path to the saved key and certificate files on the computer.
Step 4
Enter the password value in the Enter Password field (if necessary) and click the Browse button in the Save Files section to select the desired save location.
Step 5
Check the Add Signed to Filename and Add Unsigned to Filename boxes at the bottom of the SignTool application window and click the Remove Certificate button to clear the data.
Step 6
Wait until the message "The file xxxxxx.sis does not contain certificates" appears indicating the completion of the data cleansing operation, and then click the "Sign" button.
Step 7
Wait for the message "Files are signed!" and click OK.
Step 8
Wait for the message "Certificates deleted!" if you have previous electronic certificates and click the OK button to confirm the application of the selected changes.
Step 9
Click the "Clear" button to remove signed applications from the list and click the "Add" button to re-specify the path to the programs to be signed.
This action is necessary because the original list contains applications with the definition signed, which is not true after the data deletion operation has been performed. In the new list, these applications will have an unsigned definition.
Step 10
Press the “Sign” button and wait for the message “Files are signed!” To appear.
Step 11
Click OK to confirm the application of the selected changes.
