Yes. But maybe not with the openssl api's :)

Hi,
is the following picture correct ?
when creating an encrypted PKCS#7 envelope, a random AES key is generated
and encrypted with the provided RSA private key. The AES key is used to
encrypt the envelope content. The X509 certificate containing the
associated public key is included in the envelo
