5.2.4 How to change how the CMS is created
------------------------------------------

'--include-certs N'
     Using N of -2 includes all certificate except for the root cert, -1
     includes all certs, 0 does not include any certs, 1 includes only
     the signers cert and all other positive values include up to N
     certificates starting with the signer cert.  The default is -2.

'--cipher-algo OID'
     Use the cipher algorithm with the ASN.1 object identifier OID for
     encryption.  For convenience the strings '3DES', 'AES' and 'AES256'
     may be used instead of their OIDs.  The default is 'AES'
     (2.16.840.1.101.3.4.1.2).

'--digest-algo name'
     Use 'name' as the message digest algorithm.  Usually this algorithm
     is deduced from the respective signing certificate.  This option
     forces the use of the given algorithm and may lead to severe
     interoperability problems.
