[Mono-list] signcode on Centos 5

[Matthew Gertner]

Hi,

I installed Mono using the yum packages on Centos 5. The version is
1.2.4-2.el5.centos.

I'm trying to digitally sign an executable using signcode. I followed
the instructions here:
https://developer.mozilla.org/En/Signing_an_executable_with_Authenticode.
I added the three CA certificates I downloaded from GlobalSign to the
CA repository as instructed.

I had to extract the .p7b and .pvk files from the .p12 file supplied
by GlobalSign, which I did by following the instructions here:
http://wiki.cacert.org/wiki/Authenticode.

Everything seemed to go fine, but when I run the signcode command:

signcode \
 -spc (path to your public key).p7b \
 -v (path to your private key).pvk \
 -a sha1 -$ commercial \
 -n My\ Application \
 -i http://www.example.com/ \
 -t http://timestamp.verisign.com/scripts/timstamp.dll \
 -tr 10 \
 MyApp.exe

I get the following output:

Mono SignCode - version 1.2.4.0
Sign assemblies and PE files using Authenticode(tm).

I get the same error if I just run:

signcode -spc <path to my p7b>

I'm stuck. Does anyone have any idea what might be causing this?

Thanks in advance,
Matt
