More specifically, I need to emulate this openssl command:

openssl smime -sign -in $tempfile -signer $MY_CERT -inkey $MY_KEY
-outform der -nodetach -binary | \
openssl smime -encrypt -des3 -binary -outform pem
/root/sandbox_cert_key_pem.txt

I am completely at a loss to deal with the pyOpenSSL library and really
need a lift here if anyone can help me out.

TIA,
