.Sh NAME
.Nm PKCS7_set_content ,
.Nm PKCS7_content_new
.Nd set the nested contentInfo in a PKCS#7 structure
.Sh SYNOPSIS
.In openssl/pkcs7.h
.Ft int
.Fo PKCS7_set_content
.Fa "PKCS7 *outer"
.Fa "PKCS7 *inner"
.Fc
.Ft int
.Fo PKCS7_content_new
.Fa "PKCS7 *outer"
.Fa "int inner_type"
.Fc
.Sh DESCRIPTION
If the
.Fa contentType
of the
.Fa outer
PKCS7 structure is
.Vt SignedData
or
.Vt DigestedData ,
.Fn PKCS7_set_content
sets the
.Fa contentInfo
field of the
.Fa content
field of
.Fa outer
to
.Fa inner ,
without copying
.Fa inner .
If there was previous
.Fa contentInfo ,
it is freed rather than overwritten.
The rest of the internal state of
.Fa outer
and of its
.Fa content
remains unchanged.
.Pp
.Fn PKCS7_content_new
is similar except that it first allocates and initializes a new, empty
.Fa inner
object of the given
.Fa inner_type
using
.Xr PKCS7_new 3
and
.Xr PKCS7_set_type 3 .
The
.Fa inner_type
can be any of the NIDs listed in the
.Xr PKCS7_set_type 3
manual.
.Sh RETURN VALUES
These functions return 1 on success or 0 on failure.
They fail if the
.Fa contentType
of
.Fa outer
is unsupported.
.Fn PKCS7_content_new
can also fail when memory is exhausted.
In case of failure,
.Fa outer
remains unchanged.
.Sh SEE ALSO

.Xr PKCS7_new 3 ,
.Xr PKCS7_set_type 3 ,

.Sh HISTORY
These functions first appeared in SSLeay 0.8.1
and have been available since
.Ox 2.4 .
.Sh CAVEATS
Despite the function names, these functions do not set the
.Fa content
field of
.Fa outer ,
but only the
.Fa contentInfo
field inside it.
The rest of the
.Fa content
remains unchanged.
