+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBCMS_EnvelopedData_create_ex()\fR creates a \fBCMS_ContentInfo\fR structure
+with a type \fBNID_pkcs7_enveloped\fR. \fIcipher\fR is the symmetric cipher to use.
+The library context \fIlibctx\fR and the property query \fIpropq\fR are used when
+retrieving algorithms from providers.
+.PP
+\&\fBCMS_AuthEnvelopedData_create_ex()\fR creates a \fBCMS_ContentInfo\fR
+structure with a type \fBNID_id_smime_ct_authEnvelopedData\fR. \fBcipher\fR is the
+symmetric AEAD cipher to use. Currently only AES variants with GCM mode are
+supported. The library context \fIlibctx\fR and the property query \fIpropq\fR are
+used when retrieving algorithms from providers.
+.PP
+The algorithm passed in the \fIcipher\fR parameter must support ASN1 encoding of
+its parameters.
+.PP
+The recipients can be added later using \fBCMS_add1_recipient_cert\fR\|(3) or
+\&\fBCMS_add0_recipient_key\fR\|(3).
+.PP
+The \fBCMS_ContentInfo\fR structure needs to be finalized using \fBCMS_final\fR\|(3)
+and then freed using \fBCMS_ContentInfo_free\fR\|(3).
+.PP
+\&\fBCMS_EnvelopedData_create()\fR and \fBCMS_AuthEnvelopedData_create()\fR are similar to
+\&\fBCMS_EnvelopedData_create_ex()\fR and \fBCMS_AuthEnvelopedData_create_ex()\fR
+but use default values of NULL for
+the library context \fIlibctx\fR and the property query \fIpropq\fR.
+.SH NOTES
+.IX Header "NOTES"
+Although \fBCMS_EnvelopedData_create_ex()\fR, and \fBCMS_EnvelopedData_create()\fR,
+\&\fBCMS_AuthEnvelopedData_create_ex()\fR, and \fBCMS_AuthEnvelopedData_create()\fR allocate
+a new \fBCMS_ContentInfo\fR structure, they are not usually used in applications.
+The wrappers \fBCMS_encrypt\fR\|(3) and \fBCMS_decrypt\fR\|(3) are often used instead.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+If the allocation fails, \fBCMS_EnvelopedData_create_ex()\fR,
+\&\fBCMS_EnvelopedData_create()\fR, \fBCMS_AuthEnvelopedData_create_ex()\fR,
+\&\fBCMS_AuthEnvelopedData_create()\fR, \fBCMS_AuthEnvelopedData_create()\fR,
+and \fBCMS_AuthEnvelopedData_create_ex()\fR return NULL and set an
+error code that can be obtained by \fBERR_get_error\fR\|(3).
+Otherwise, they return a pointer to the newly allocated structure.
+.SH "SEE ALSO"

+.SH HISTORY
+.IX Header "HISTORY"
+The \fBCMS_EnvelopedData_create_ex()\fR method was added in OpenSSL 3.0.
+.PP
+\&\fBCMS_AuthEnvelopedData_create()\fR and \fBCMS_AuthEnvelopedData_create_ex()\fR
+were added in OpenSSL 3.5.
