=head1 DESCRIPTION
CMS_encrypt() creates and returns a CMS envelopedData structure. B<certs>
CMS_encrypt() creates and returns a CMS EnvelopedData structure. B<certs>
is a list of recipient certificates. B<in> is the content to be encrypted.
B<cipher> is the symmetric cipher to use. B<flags> is an optional set of flags.
=head1 NOTES
Only certificates carrying RSA keys are supported in CMS and envelopedData so
the recipient certificates supplied to this function must all contain RSA
public keys, though they do not have to be signed using the RSA algorithm.
Only certificates carrying RSA keys are supported so the recipient certificates
supplied to this function must all contain RSA public keys, though they do not
have to be signed using the RSA algorithm.
EVP_des_ede3_cbc() (triple DES) is the algorithm of choice for S/MIME use
because most clients will support it.
Some old "export grade" clients may only support weak encryption using 40 or 64
bit RC2. These can be used by passing EVP_rc2_40_cbc() and EVP_rc2_64_cbc()
respectively.
The algorithm passed in the B<cipher> parameter must support ASN1 encoding of
its parameters.
