Authenticode’s Signcode

Some of you may be annoyed by the way signcode.exe keeps popping up the password prompt when trying to sign file from command line. There’s a workaround, however.

The utility catches password prompt and autoenters the password. After a minute of inactivity it quits. For use in bacth files like this:

start /b AutomateSigncodePassword.exe my-authenticode-password
signcode %1 -spc mycredentials.spc -v myprivatekey.pvk -t

Resource Updater

Sometimes an automated update of the binary resource is required, to update version, product name, some custom string etc. We have an utility for this and and it found itsself being very useful.

We are unlikely to document it, I just leave a sample code illustrating how it all works.


Image = new ActiveXObject(“AlaxInfoResourceTools.Image”);
WScript.Echo(“Product Version: ” + Image.VersionInfo.ProductVersionString);
WScript.Echo(“File Version: ” + Image.VersionInfo.FileVersionString);
var ProductName = Image.VersionInfo.GetString(0, “ProductName”);
var OemProductName = Image.VersionInfo.GetString(0, “OemProductName”);
WScript.Echo(“ProductName: ” + ProductName);
WScript.Echo(“OemProductName: ” + OemProductName);
Image.VersionInfo.SetString(0, “OemProductName”, “// ” + ProductName);

Curious ones are invited to open type library to find out the syntax.
