c# - Reading executing assembly signature pfx / cert -

this academic question trying understand new material. not academic in sense of formal school in sense of ongoing education , wanting handle on area of development have not been exposed before.

so in understanding create assembly , "signing it" have created strong name / x509certificate.

so create empty winapp. go project properties on signing tab , sign assembly using password.

a file testing.pfx added project.

in form load execute code thinking see assembly signing cert don't null...??

assembly ass = assembly.getexecutingassembly(); module mod = ass.getmodules().first(); x509certificate cert = mod.getsignercertificate();

cert null. why that? doing wrong retrieve cert or have things jumbled in head , looking isn't looking?

thank you

edit

@p e p have used next after reading post , msdn.

signtool sign /a c:/....../myfile.exe

signtool sign /f c:/....../mycert.pfx /p mypassword c:/....../myfile.exe

both said completed success. running code block above still produces null cert.

now may have missed or doing wrong working visual studio debug version , path exe used signing.

c:....\licensedcontroltest\obj\x86\debug

you need authenticode sign assembly. can using file signing tool (signcode.exe) sign assembly authenticode signature. run command using signcode authenticode sign assembly.

if @ doc getsignercertificate, see null expected if assembly not authenticode signed.

signcode /spc mycertificate.spc /v mykey.pvk myassembly

that's basics, can find more info here on msdn http://msdn.microsoft.com/en-us/library/9sh96ycy(v=vs.80).aspx.
