Subject: Multiple symmetric algo-encrypted data in single S/MIME message
My organisation users need to communicate with 2 groups of users, on different S/MIME secure mail systems. The problem lies in them using different symmetric algorithms for data encryption. I am assessing possibility of building a single mail client to compose and send S/MIME messages to selected users on both nets, at the same time (i.e. at one sending operation). This means that there would logically be 2 sets of encrypted blobs in the S/MIME message sent out, but I am not sure if this is supported in S/MIME format.
The easy way out of course is to send out the same mails twice separately, to users of each group, as what we are doing now. This however is neither efficient nor elegant.
Any suggestion/recommendation would be greatly appreciated.
