Issue
Certificates
When
you
have
a
Certificate
Signing
Request
(CSR)
that
needs
to
be
certificated
by
the
root
CA
of
the
device,
you
can
issue
the
request
here
and
let
Root
CA
sign
it.
There
are
two
approaches
to
issue
a
certificate.
One
is
from
a
CSR
file
importing
from
the
managing
PC
and
another
is
copy
‐
paste
the
CSR
codes
in
gateway’s
web
‐
based
utility,
and
then
click
on
the
"Sign"
button.
In
"Issue
Certificates"
page,
there
are
three
configuration
windows
for
the
"Issue
Certificates"
function.
The
"Certificate
Signing
Request
(CSR)
Import
from
a
File"
window
let
you
browse
the
directories
and
file
list
of
the
managing
PC
to
choose
a
CSR
file
and
import
it
as
the
certificate
signing
request.
The
gateway
will
generates
the
certificate
based
on
the
dedicated
CSR
by
clicking
on
the
"Sign"
button
in
the
window.
Certainly,
only
the
gateway
be
the
root
CA
and
it
can
sign
the
requests
to
certify.
Another
approach
to
import
a
CSR
to
the
gateway
for
signing
is
to
copy
the
PEM
‐
formatted
CSR
contents
and
paste
them
directly
into
the
blank
space
in
the
"Certificate
Signing
Request
(CSR)
Import
from
a
PEM"
window.
The
gateway
will
generates
the
certificate
based
on
the
pasted
CSR
contents
by
clicking
on
the
"Sign"
button.
A
successful
signing
will
show
the
"Signed
Certificate
View"
window
to
display
the
resulted
certificate
contents.
And
you
can
download
the
certification
to
a
file
in
the
managing
PC.

Import
from
a
File
Only
the
gateway
plays
the
root
CA
role
can
sign
CSRs
and

certificates
for
others.
In
this
window,
you
can
browse
the
directory
architecture
and
file
system
in
the
managing
PC
to
choose
one
CSR
file
for
uploading
unsigned
certificates
to
the
gateway.
