-=head1 NAME
-
-CMS_add1_recipient_cert, CMS_add0_recipient_key - add recipients to a CMS enveloped data structure
-
-=head1 SYNOPSIS
-
- #include <openssl/cms.h>
-
- CMS_RecipientInfo *CMS_add1_recipient_cert(CMS_ContentInfo *cms, X509 *recip, unsigned int flags);
-
- CMS_RecipientInfo *CMS_add0_recipient_key(CMS_ContentInfo *cms, int nid, unsigned char *key, size_t keylen, unsigned char *id, size_t idlen, ASN1_GENERALIZEDTIME *date, ASN1_OBJECT *otherTypeId, ASN1_TYPE *otherType);
-
-=head1 DESCRIPTION
-
-CMS_add1_recipient_cert() adds recipient B<recip> to CMS_ContentInfo enveloped
-data structure B<cms> as a KeyTransRecipientInfo structure.
-
-CMS_add0_recipient_key() adds symmetric key B<key> of length B<keylen> using
-wrapping algorithm B<nid>, identifier B<id> of length B<idlen> and optional
-values B<date>, B<otherTypeId> and B<otherType> to CMS_ContentInfo enveloped
-data structure B<cms> as a KEKRecipientInfo structure.
-
-The CMS_ContentInfo structure should be obtained from an initial call to
-CMS_encrypt() with the flag B<CMS_PARTIAL> set.
-
-=head1 NOTES
-
-The main purpose of this function is to provide finer control over a CMS
-enveloped data structure where the simpler CMS_encrypt() function defaults are
-not appropriate. For example if one or more KEKRecipientInfo structures
-need to be added. New attributes can also be added using the returned
-CMS_RecipientInfo structure and the CMS attribute utility functions.
-
-OpenSSL will by default identify recipient certificates using issuer name
-and serial number. If B<CMS_USE_KEYID> is set it will use the subject key
-identifier value instead. An error occurs if all recipient certificates do not
-have a subject key identifier extension.
-
-Currently only AES based key wrapping algorithms are supported for B<nid>,
-specifically: NID_id_aes128_wrap, NID_id_aes192_wrap and NID_id_aes256_wrap.
-If B<nid> is set to B<NID_undef> then an AES wrap algorithm will be used
-consistent with B<keylen>.
-
-=head1 RETURN VALUES
-
-CMS_add1_recipient_cert() and CMS_add0_recipient_key() return an internal
-pointer to the CMS_RecipientInfo structure just added or NULL if an error
-occurs.
