CMS_AuthEnvelopedData_create_ex() creates a CMS_ContentInfo structure with a type NID_id_smime_ct_authEnvelopedData. cipher is the symmetric AEAD cipher to use. Currently only AES variants with GCM mode are supported. The library context libctx and the property query propq are used when retrieving algorithms from providers.
The algorithm passed in the cipher parameter must support ASN1 encoding of its parameters.
The recipients can be added later using CMS_add1_recipient_cert(3) or CMS_add0_recipient_key(3).
The CMS_ContentInfo structure needs to be finalized using CMS_final(3) and then freed using CMS_ContentInfo_free(3).
CMS_EnvelopedData_create() and CMS_AuthEnvelopedData_create are similar to CMS_EnvelopedData_create_ex() and CMS_AuthEnvelopedData_create_ex() but use default values of NULL for the library context libctx and the property query propq.
