Is it possible to dual-sign installer and uninstaller with sha1 and sha256 certificates?

问题

Is it possible in Inno Setup to sign the Uninstaller and Installer with sha1 and sha256 at the same time?

I know that it is possible to sign the Executable with both certs via command tool, but want to know if this is possible to achieve with SignTool in Inno.

Yes, this is possible. As @Wosi suggested you can write a batch and then call it with $f parameter added.

Sample batch (signtool.bat):

@echo off

"PATH_TO_SIGNTOOL\signtool.exe" sign /v /du "COMPANY_NAME" /fd sha1 /t "http://timestamp.verisign.com/scripts/timstamp.dll" /f "sha1_cert.pfx" /p PASSWORD %1

set SIGN_RESULT_1=%ERRORLEVEL%

"PATH_TO_SIGNTOOL\signtool.exe" sign /as /v /du "COMPANY_NAME" /fd sha256 /tr "http://timestamp.comodoca.com/rfc3161" /td sha256 /f "sha256_cert.pfx" /p PASSWORD %1

set SIGN_RESULT_2=%ERRORLEVEL%

set /a RESULT=%SIGN_RESULT_1%+%SIGN_RESULT_2%

if %RESULT% NEQ 0 (
   echo Warning! Signing failed with %SIGN_RESULT_1% for sh1 and %SIGN_RESULT_2% for sha256
   pause
   exit /B %RESULT%
) 

echo Signing succeeded
exit /B 0

Then in Inno Setup you can call signtool.bat $f where $f will be passed to %1 for the batch.

For Windows XP compatibility for sha1: removed /as, /tr replaced with /t, removed /td (as it requires /tr)

I will leave it here as maybe someone could find it helpful.

I'm using InnoSetup 5.5.9. I compile my script from the command line using ISCC. My setup script includes these two lines in the [Setup] section:

SignTool=sha1
SignTool=sha256

The ISCC command looks like:

ISCC "/ssha1=signtool.exe /f <cert.pfx> /p <certpwd> /fd SHA1 /t <timestamp.url> /v $f" "/ssha256=signtool.exe /f <cert.pfx> /p <certpwd> /fd SHA256 /tr <timestamp.url> /td SHA256 /as /v $f" setup.iss

Innosetup will sign the install and uninstall with both certs.
