you need to export the certificate in pfx format (include private key)

make sure when you export, you need to include private key :) [tell him the password on the pfx file as well]

follow the instruction https://technet.microsoft.com/en-au/library/dd261744.aspx

then he should need to convert to PEM or soemthing he can use
