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 envelope attributes.
If so, would it be possible in principle to decrypt an encrypted PKCS#7 envelope only knowing which AES key was used ?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 envelope attributes.
