Get enveloped data from MIME

Question

Hello all

I am receiving some encrypted data on a S/MIME message (not an e-mail, but SOAP request over SSL) and I need to get it out of the package.

Does anyone know of any C/C++ interface to do it?

I need something that just strips the SMIME headers and leaves me with the enveloped data, which I would then decrypt to get the MIME package and the get the message itself.

Any ideas?
