I used the following command:
C:\Verisign>signtool sign /v /ac "MSCV-VSClass3.cer"/s MY /n "ABC Company LTD" /t http://timestamp.verisign.com/scripts/timstamp.dll TestRun.jar
and I get the following result:
SignTool Error: This file format cannot be signed because it is not recognized.
Can someone help me to resolve this issue? Does VeriSign not support signing jars?
