After I switched OS for my development from Windows to Mac, I always try to find options that minimize the need for starting Windows on
VirtualBox. I had to use Windows for digitally signing exes and dlls. Today I found
osslsigncode to sign windows binaries on non-windows platform. One less reason to boot Windows and it is much quicker than on Windows :)
Here is how I did it on Mac:
1. Download source zip, unzip, compile and install osslsigncode from http://sourceforge.net/projects/osslsigncode/
cd osslsigncode-1.3
./configure
make
make install
2. Generate spc and private key files in DER format from .p12 file
openssl pkcs12 -in CodeSigning.p12 -nokeys -clcerts -out CodeSigning-CL.crt.pem
openssl pkcs12 -in CodeSigning.p12 -nokeys -cacerts -out CodeSigning-CA.crt.pem
openssl pkcs12 -in CodeSigning.p12 -nocerts -nodes -out CodeSigning-CL.key.pem
openssl crl2pkcs7 -certfile CodeSigning-CL.crt.pem -certfile CodeSigning-CA.crt.pem -nocrl -outform DER -out CodeSigning-CL.spc.der
openssl rsa -in CodeSigning-CL.key.pem -outform DER -out CodeSigning-CL.key.der
3. Now sign the binary
osslsigncode -spc CodeSigning-CL.spc.der -key CodeSigning-CL.key.der -n "Description" -i "http://www.mydomain.com" -in file.dll -out signed-file.dll
