I am using makemime library for the enryption of my xml file.I want to create a smime.p7m file which when decrypted should look something like this

What I am able to achieve is that I am using makemime to encrypt the data that is the content of my xml file and then I create the data first in the same format that is mentioned above and I try to create the smime.p7m file. Can any one tell me that is this the correct way to encrypt the file or is there any ssl command through which I can make the content of my encrypted file look exactly same. I am using OpenSSL 0.9.8o version on windows base enviornment.
Thanks in advance.
