type, decoding the message into output. It uses the private key of the
PKCS7 object passed in to decrypt the message.
Note that if the EnvelopedData is encrypted using an ECC key and the
KeyAgreementRecipientInfo structure, then either the HAVE_AES_KEYWRAP
build option should be enabled to enable the wolfcrypt built-in AES key
wrap/unwrap functionality, or a custom AES key wrap/unwrap callback should
be set with wc_PKCS7_SetAESKeyWrapUnwrapCb(). If neither of these is true,
decryption will fail.
\return On successfully extracting the information from the message,
returns the bytes written to output
\return BAD_FUNC_ARG Returned if one of the input parameters is invalid
