Hi All,
small question - I was playing around with the CMS interface and I was
wondering what is the right way to generate a signed and encrypted CMS.
In particular, for PKCS#7, you could use the signed_and_encrypted
choice... but in CMS, there is the envelopedData ... but that does not
allow for signing... ??? And for the signed data, there is the
signedData type... but that does not allow for encryption... The
EncryptedData is for use with PSK - not a case I am interested into...
So... what is the right way of doing it ?
And when you receive such CMS, how do you extract the encryption
algorithm from the EnvelopedData/EncryptedContentInfo (I can not find
the helper function...) ?
Cheers,
Max
