Wrap a CMS object in an S/MIME entity.

This forms an S/MIME entity with a Content-Type of application/pkcs7-mime from a binary CMS object.
It works in file-to-file mode only.
The input file is expected to be a binary CMS object of type enveloped-data, signed-data or compressed-data;
otherwise it is an error.
The type of input file is detected automatically.
The output is a text file with the correct S/MIME headers according to [SMIME-MSG].
By default the body is encoded in base64.
Use the PKI_SMIME_ENCODE_BINARY option to encode the body in "binary" instead.
Use the PKI_SMIME_ADDX option to change the Content-Type to
application/x-pkcs7-mime for compatibility with legacy applications.
S/MIME signed messages with the multipart/signed format are currently not supported.
nRet = SMIME_Wrap("cmsalice2bob-smime-env.txt", "cmsalice2bob.p7m", "", 0)
In this example, the binary file cmsalice2bob.p7m was created using
CMS_MakeEnvData.
The output file should look like the following.
Content-Type: application/pkcs7-mime;
smime-type=enveloped-data;
id="smime.p7m"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
fileid="smime.p7m"
