Dual sign - No signature present RRS feed

  • Question

  • Hi everyone,

    I signed a driver with dual sign - SHA1 and SHA256 to have compatibility from Windows 7 to Windows 10.

    The sign is OK, the driver installs correctly, and when I open cat file properties I can see the both SHA1 and SHA256 signs.

    But for "Details" on SHA256 sign, I got the message "No signature was present in the subject".

    Is there something wrong on the sign process?


    With the only SHA256 sign, the details are OK.


    Here how dual sign:

    SignTool sign /f certificate_sha1.pfx /p PASSWORD /fd sha1 /t /v %InfPath%\*.cat"

    SignTool sign /f certificate_sha2.pfx /p PASSWORD /fd sha256 /tr /td sha256 /as /v "%InfPath%\*.cat"


    signtool verify is successfull

    but on SHA256 Details...

    What is wrong on signtool command?

    Many thanks for your help
