<tp:docstring xmlns="http://www.w3.org/1999/xhtml">
<p>This interface exists to expose security information about
<tp:dbus-ref namespace="ofdT">Channel</tp:dbus-ref>s. The two
properties are sometimes immutable and can be used to make
decisions on how cautious to be about transferring sensitive
data. The special case of <tp:dbus-ref
namespace="ofdT.Channel.Type">ServerAuthentication</tp:dbus-ref>
channels is one example of where the two properties are
immutable.</p>
<p>For example, clients MAY use these properties to decide
whether the <code>PLAIN</code> mechanism is acceptable for a
<tp:dbus-ref
namespace="ofdT.Channel.Interface">SASLAuthentication</tp:dbus-ref>
channel.</p>

<p>True if this channel occurs over an encrypted
connection. This <strong>does not</strong> imply that steps
have been taken to avoid man-in-the-middle attacks.</p>
<tp:rationale>
<p>For future support for <a
href="http://tools.ietf.org/html/rfc5056">RFC 5056 Channel
Binding</a> it is desirable to be able to use some SASL
mechanisms over an encrypted connection to an unverified peer,
which can prove that it is the desired destination during
the SASL negotiation.</p>

<p>True if this channel occurs over a connection that is

previously negotiated, and the TLS certificate has been
verified against a configured certificate authority or
