<chapter id="introduction"> <title>Introduction</title> 

<para>&kleopatra; is the &kde; tool for managing X.509 certificates in
the &gpgsm; keybox and for retrieving certificates from
<acronym>LDAP</acronym> servers.</para>

<para>&kleopatra; can be started from &kmail;'s <guimenu>Tools</guimenu>
menu, as well as from the command line. The &kleopatra; executable is
named <userinput><command>kleopatra</command></userinput>.</para>

<note><para>This program is named after Cleopatra, a famous female
Egyptian pharaoh that lived at the time of Julius Caesar, whom she is
said to have had an intimate relationship with.</para>

<para>The name was chosen since this program originates from the
<ulink url="http://www.gnupg.org/aegypten2/">&Auml;gypten
Projects</ulink> (&Auml;gypten is German for Egypt). &kleopatra; is the
German spelling of Cleopatra.</para></note>

</chapter>

<chapter id="functions"><title>Main Functions</title>

<sect1 id="functions-view"><title>Viewing the Local Keybox</title>

<!-- Viewing and Refreshing, also Validation -->

<para>&kleopatra;'s main function is to display and edit the contents
of the local keybox, which is similar to &gpg;'s concept of keyrings,
albeit one should not stretch this analogy too much.</para>

<para>The main window is divided into the large key listing area, the
menubar and the <link linkend="functions-search">search bar</link> on
top, and a status bar at the bottom.</para>

<para>Each line in the key list corresponds to one certificate,
identified by the so-called <guilabel>Subject &dn;</guilabel>. &dn; is
an acronym for <quote>Distinguished Name</quote>, a hierarchical
identifier, much like a file system path with an unusual syntax, that is
supposed to globally uniquely identify a given certificate.</para>

<para>To be valid, and thus usable, (public) keys need to be signed by
a &ca; (Certification Authority). These signatures are called
certificates, but usually the terms <quote>certificate</quote> and
<quote>(public) key</quote> are used interchangeably, and we will not
distinguish between them in this manual either, except when explicitly
noted. The name of the &ca; which issued the certificate (its &dn;)
is shown in the <guilabel>Issuer &dn;</guilabel> column.</para>

<para>&ca;s must in turn be signed by other &ca;s to be valid. Of
course, this must end somewhere, so the top-level &ca; (root-&ca;)
signs its key with itself (this is called a self-signature). Root
certificates thus need to be assigned validity (commonly called trust)
manually, &eg; after comparing the fingerprint with the one on the
website of the &ca;. This is typically done by the system administrator or
the vendor of a product using certificates, but can be done by the
user via &gpgsm;'s command line interface.</para>

<para>To see which of the certificates are root certificates, you can
either compare <guilabel>Subject &dn;</guilabel> and <guilabel>Issuer
&dn;</guilabel>, or you switch to hierarchical keylist mode with <link
linkend="view-hierarchical-key-list"><menuchoice><guimenu>View</guimenu>
<guimenuitem>Hierarchical Key List</guimenuitem></menuchoice></link>.</para>

<para>You can see the details of any certificate by double-clicking it
or using <link linkend="view-certificate-details"><menuchoice><guimenu>View</guimenu>
<guimenuitem>Certificate Details</guimenuitem></menuchoice></link>. This opens a
dialog that shows the most common properties of the certificate, its
certificate chain (&ie; the chain of issuers up to the root-&ca;), and
a dump of all information the backend is able to extract from the
certificate.</para>

<para>If you change the keybox without using &kleopatra; (&eg; using
&gpgsm;'s command line interface), you can refresh the view with <link
linkend="view-redisplay"><menuchoice><shortcut><keycombo action="simul">
<keycap>F5</keycap></keycombo></shortcut><guimenu>View</guimenu>
<guimenuitem>Redisplay</guimenuitem></menuchoice></link>.</para>

<para>Since validating a key may take some time (&eg; CRLs might need
to be fetched), the normal keylisting does not attempt to check the
validity of keys. For this, <link linkend="certificates-validate">
<menuchoice><shortcut><keycombo action="simul">&Shift;<keycap>F5</keycap></keycombo>
</shortcut><guimenu>Certificates</guimenu><guimenuitem>Validate</guimenuitem></menuchoice></link>, a
special variant of <link
linkend="view-redisplay"><menuchoice><shortcut><keycombo action="simul">
<keycap>F5</keycap></keycombo></shortcut><guimenu>View</guimenu>
<guimenuitem>Redisplay</guimenuitem></menuchoice></link>, is provided. It
either checks the selected certificates, or all keys if none are
selected.</para>

</sect1>

<sect1 id="functions-search"><title>Searching and Importing Certificates</title>

<para>Most of the time, you will acquire new certificates by verifying
signatures in emails, since certificates are embedded in the
signatures made using them most of the time. However, if you need to
send a mail to someone you have not yet had contact with, you need to
fetch the certificate from an LDAP directory (although &gpgsm; can do
this automatically), or from a file. You also need to import your own
certificate after receiving the &ca; answer to your certification
request.</para>

<para>To search for a certificate in an LDAP directory, switch the
dropdown menu of the search bar from <guilabel>in Local
Certificates</guilabel> to <guilabel>in External
Certificates</guilabel>, enter some text (&eg; the name of the person
you want the certificate for) into the line edit, and click on the
<guilabel>Find</guilabel> icon. The results will be displayed in the
key list below the search bar, where you can select certificates to
either look at them with <link linkend="view-certificate-details">
<menuchoice><guimenu>View</guimenu><guimenuitem>Certificate Details</guimenuitem></menuchoice></link> or
download them with <link linkend="certificates-download">
<menuchoice><guimenu>Certificates</guimenu><guimenuitem>Download</guimenuitem></menuchoice></link> into the
local keybox. Note that you can also download the certificate from the
details dialog, using the <guilabel>Import to Local</guilabel>
button.</para>

<para>You can configure the list of LDAP servers to search in the
<link linkend="configuration-directory-services"><guilabel>Directory
Services</guilabel></link> page of &kleopatra;'s <link
linkend="configuration">configure dialog</link>.</para>

<para>If you received the certificate as a file, try <link
linkend="file-import-certificates"><menuchoice><guimenu>File</guimenu>
<guimenuitem>Import Certificates...</guimenuitem></menuchoice></link>. &gpgsm; needs to understand the
format of the certificate file; please refer to &gpgsm;'s manual for a
list of supported file formats.</para>

<para>If you did not <link linkend="functions-newkey">create your
keypair with &gpgsm;</link>, you also need to manually import the
public key (as well as the secret key) from the PKCS#12 file you got from
the &ca;. You can do this on the command line with <link
linkend="commandline-option-import-certificate"><userinput><command>kleopatra
&commandline-option-import-certificate;
<filename>filename</filename></command></userinput></link> or from
within &kleopatra; with <link
linkend="file-import-certificates"><menuchoice><guimenu>File</guimenu>
<guimenuitem>Import Certificates...</guimenuitem></menuchoice></link>,
just as you would to for <quote>normal</quote> certificates.</para>

</sect1>

<sect1 id="functions-newkey"><title>Creating New Key Pairs</title>

<para>The menu item <link linkend="file-new-key-pair"><menuchoice>
<guimenu>File</guimenu><guimenuitem>New Key Pair...</guimenuitem></menuchoice></link> starts the
certificate-request-creating wizard which will guide you through a
number of steps to create a certificate request; this request can, on the 
last page of the wizard, either be sent to a certificate authority (&ca;)
to be signed or saved to a file (for example to a floppy, so it can be
shipped to the &ca;).</para> <para>Whenever you are done with a step in
the wizard, press <guibutton>Next</guibutton> to go to the next step
(or <guibutton>Back</guibutton> to review steps that are already
completed). The certificate request creation can be canceled at any
time by pressing the <guibutton>Cancel</guibutton> button.
</para>
<para>The first step in the wizard is to type in your personal data
for the certificate. The fields to fill out are:
<itemizedlist>
<listitem>
<para><guilabel>Name:</guilabel> Your name;</para>
</listitem>
<listitem>
<para><guilabel>Location:</guilabel>The town or city in which you live;</para>
</listitem>
<listitem>
<para><guilabel>Organization:</guilabel>The organization you represent
(for example, the company you work for);</para>
</listitem>
<listitem>
<para><guilabel>Department:</guilabel>The organizational unit you are
in (for example, "Logistics");</para> 
</listitem>
<listitem>
<para><guilabel>Country code:</guilabel>The two letter code for the
country in which you are living (for example, "US");</para>
</listitem>
<listitem>
<para><guilabel>Email address:</guilabel>Your email address; be sure
to type this in correctly&mdash;this will be the address people will be
sending mail to when they use your certificate.</para>
</listitem>
</itemizedlist>
</para><para>
The next step in the wizard is to select whether to store the
certificate in a file or send it directly to a &ca;. You will have to
specify the filename or email address to send the certificate request to.
</para></sect1>


<sect1 id="functions-keybox-management"><title>Keybox Management</title>

<para>In addition to <link linkend="functions-view">list and
validate</link>, <link linkend="functions-search">search and
import</link> certificates and <link
linkend="functions-newkey">creating new ones</link>, &kleopatra; also
has some less often used functions that help you manage your local
keybox.</para>

<para>These functions include deleting certificates from the local
keybox with <link linkend="certificates-delete"><menuchoice><shortcut>
<keycombo action="simul"><keycap>Delete</keycap></keycombo></shortcut>
<guimenu>Certificates</guimenu><guimenuitem>Delete</guimenuitem></menuchoice></link>, as well 
as manual handling of CRLs (<link linkend="certificates-refresh-crls">

<para>This mode of operation is called <quote>decentralized key

<para>This function only has an effect on certificates which define a

<para>You may use this &eg; if you have sideband knowledge that a key

happen at the next scheduled CRL update.</para>

<warning><para>Excessive use of this function might put a high load on

<para>Each of its pages is described in the sections below.</para>

<sect1 id="configuration-directory-services"><title>Configuring <guilabel>Directory Services</guilabel></title>

<para>On this page, you can configure which LDAP servers to use for
certificate searches. You can also configure their order, as well as
some selected LDAP-related settings from the dynamic backend
configuration dialog, available via <link
linkend="settings-configure-gpgme-backend"><menuchoice><guimenu>Settings</guimenu>
<guimenuitem>Configure GpgME Backend...</guimenuitem></menuchoice></link>.</para>

<para>To add a new server, click on the <guilabel>Add
Service...</guilabel> button. In the dialog that appears, you can set
the <guilabel>Server name</guilabel>, the <guilabel>Port</guilabel>
(preset to the default LDAP port), the <guilabel>Base &dn;</guilabel>
(sometimes referred to as the search root or search base), and the
usual <guilabel>User name</guilabel> and
<guilabel>Password</guilabel>, both of which are only needed if the
server requires authentication. Clicking <guilabel>OK</guilabel> adds
the server details to the list of servers, while
<guilabel>Cancel</guilabel> dismisses the input.</para>

<para>To remove a server from the search list, select it in the list,
then press the <guilabel>Remove Service</guilabel> button.</para>

<para>To change the relative search order of servers, select one of
them and move it up or down with the arrow buttons right next to the
list.</para>

<para>To set the LDAP timeout, &ie; the maximum time the backend will
wait for a server to respond, simply use the corresponding input field
labelled <guilabel>LDAP timeout</guilabel>.</para>

<para>If one of your servers has a large database, so that even
reasonable searches like <userinput>Smith</userinput> hit the
<guilabel>maximum number of items returned by query</guilabel>, you
might want to increase this limit. You can find out easily if you hit
the limit during a search, since a dialog box will pop up in that
case, telling you that the results have been truncated.</para>

<note><para>Some servers may impose their own limits on the number of
items returned from a query. In this case, increasing the limit here
will not result in more returned items.</para></note>

</sect1>

<sect1 id="configuration-appearance"><title>Configuring visual <guilabel>Appearance</guilabel></title>

<para>&kleopatra; allows you to customize the appearance of
(validated) keys in the list view. This includes the foreground (text)
and background colors, as well as the font.</para>

<para>Each <guilabel>Key Category</guilabel> on the left is assigned a
set of colors and a font in which keys belonging to that category are
displayed. The category list also acts as a preview of the
settings. Categories can be freely defined by the administrator or the
power user, see <xref linkend="admin-key-filters"/> in <xref
linkend="admin"/>.</para>

<para>To change the text (foreground) color of a category, select it
in the list, and press the <guilabel>Set Text Color...</guilabel>
button. The standard &kde; color selection dialog will appear where
you can select or create a new color.</para>

<para>Changing the background color is done in the same way, just press
<guilabel>Set Background Color...</guilabel> instead.</para>

<para>To change the font, you basically have two options:</para>

<orderedlist>
<listitem><para>Modify the standard font, used for all list views in
&kde;</para></listitem>
<listitem><para>Use a custom font.</para></listitem>
</orderedlist>

<para>The first option has the advantage that the font will follow
whichever style you choose &kde;-wide, whereas the latter gives you
full control over the font to use. The choice is yours.</para>

<para>To use the modified standard font, select the category in the
list, and check or uncheck the font modifiers
<guilabel>Italic</guilabel>, <guilabel>Bold</guilabel>, and/or
<guilabel>Strikeout</guilabel>. You can immediately see the effect on
the font in the category list.</para>

<para>To use a custom font, press the <guilabel>Set Font...</guilabel>
button. The standard &kde; font selection dialog will appear where you
can select the new font. Note that you can still use the font
modifiers to change the custom font, just as for modifying the
standard font.</para>

<para>To switch back to the standard font, you need to press the
<guilabel>Default Appearance</guilabel> button.</para>

<sect1 id="configuration-dn-order"><title>Configuring the <guilabel>&dn;Attribute Order</guilabel></title>

<para>Although &dn;s are hierarchical, the order of the individual
components (called relative &dn;s (RDNs), or &dn; attributes) is not
defined. The order in which the attributes are shown is thus a matter
of personal taste or company policy, which is why it is configurable in
&kleopatra;.</para>

<note><para>This setting does not only apply to &kleopatra;, but to all
applications using &kleopatra; Technology. At the time of this
writing, these include &kmail;, &kaddressbook;, as well as &kleopatra;
itself, of course.</para></note>

<para>This configuration page basically consists of two lists, one for
the known attributes (<guilabel>Available attributes</guilabel>), and
one describing the <guilabel>Current attribute order</guilabel>.</para>

<para>Both lists contain entries described by the short from of the
attribute (&eg; <guilabel>CN</guilabel>) as well as the spelled-out
form (<guilabel>Common Name</guilabel>).</para>

<para>The <guilabel>Available attributes</guilabel> list is always
sorted alphabetically, while the <guilabel>Current attribute
order</guilabel> list's order reflects the configured &dn; attribute
order: the first attribute in the list is also the one displayed
first.</para>

<para>Only attributes explicitly listed in the <guilabel>Current
attribute order</guilabel> list are displayed at all. The rest is
hidden by default.</para>

<para>However, if the placeholder entry <guilabel>_X_</guilabel>
(<guilabel>All others</guilabel>) is in the <quote>current</quote>
list, all unlisted attributes (whether known or not), are inserted at
the point of <guilabel>_X_</guilabel>, in their original relative
order.</para>

<para>A small example will help to make this more clear:</para>

<informalexample>
<para>Given the &dn;</para>
<blockquote>
<para>
 O=&kde;, C=US, CN=Dave Devel, X-BAR=foo, OU=&kleopatra;, X-FOO=bar,
</para>
</blockquote>
<para>the default attribute order of <quote>CN, L, _X_, OU, O,
C</quote> will produce the following formatted &dn;:</para>
<blockquote>
<para>
 CN=Dave Devel, X-BAR=foo, X-FOO=bar, OU=&kleopatra;, O=&kde;, C=US
</para>
</blockquote>
<para>while <quote>CN, L, OU, O, C</quote> will produce</para>
<blockquote>
<para>
 CN=Dave Devel, OU=&kleopatra;, O=&kde;, C=US
</para>
</blockquote>
</informalexample>

<para>To add an attribute to the display order list, select it in the
<guilabel>Available attributes</guilabel> list, and press the
<guilabel>Add to current attribute order</guilabel> button.</para>

<para>To remove an attribute from the display order list, select it in
the <guilabel>Current attribute order</guilabel> list, and press the
<guilabel>Remove from current attribute order</guilabel> button.</para>

<para>To move an attribute to the beginning (end), select it in the
<guilabel>Current attribute order</guilabel> list, and press the
<guilabel>Move to top</guilabel> (<guilabel>Move to bottom</guilabel>)
button.</para>

<para>To move an attribute up (down) one slot only, select it in the
<guilabel>Current attribute order</guilabel> list, and press the
<guilabel>Move one up</guilabel> (<guilabel>Move one down</guilabel>)
button.</para>

<chapter id="admin"><title>Administrator's Guide</title>

<para>This Administrator's Guide describes ways to customize &kleopatra; that
are not accessible via the &GUI;, but only via config files.</para>

<para>It is assumed that the reader is familiar with the technology
used for &kde; application configuration, including layout,
file system location and cascading of &kde; config files, as well as
the KIOSK framework.</para>

<sect1 id="admin-certificate-request-wizard"><title>Customization of the Certificate-Creation Wizard</title>

<para>&kleopatra; allows you to customize the fields that the user is
allowed to enter in order to create their certificate.</para>

<para>Create a group called
<literal>CertificateCreationWizard</literal> in the system-wide
<filename>kleopatrarc</filename>. If you want a custom order of
attributes or if you only want certain items to appear, create a key
called <varname>DNAttributeOrder</varname>. The argument is one or
more of <varname>CN,SN,GN,L,T,OU,O,PC,C,SP,DC,BC,EMAIL</varname> If
you want to initialize fields with a certain value, write something like
Attribute=value. If you want the attribute to be treated as a required
one, append an exclamation mark
(e.g. <varname>CN!,L,OU,O!,C!,EMAIL!</varname>, which happens to be
the default configuration).</para>

<para> Using the <acronym>KIOSK</acronym> mode modifier
<varname>$e</varname> allows to retrieve the values from
environment variables or from an evaluated script or binary. If you
want to disallow editing of the respective field in addition, use the
modifier <varname>$i</varname>.  If you want to disallow the use
<guibutton>Insert My Address</guibutton> button, set
<varname>ShowSetWhoAmI</varname> to false.</para>

<tip><para> Due to the nature of the &kde; <acronym>KIOSK</acronym>
framework, using the immutable flag (<varname>$i</varname>) makes it
impossible for the user to override the flag. This is intended
behavior. <varname>$i</varname> and <varname>$e</varname> can be used
with all other config keys in &kde; applications as well.</para></tip>

<para>The following example outlines possible customizations:</para>

<para>
<programlisting>
[CertificateCreationWizard] 
;Disallow to copy personal data from the addressbook, do not allow local override
ShowSetWhoAmI[$i]=false

;sets the user name to $USER
CN[$e]=$USER

;sets the company name to "My Company", disallows editing
O[$i]=My Company

;sets the department name to a value returned by a script
OU[$ei]=$(lookup_dept_from_ip)

; sets country to DE, but allows for changes by the user
C=DE

      <note>
	<para>
	  Some of the more interesting criteria, such as
	  <varname>is-revoked</varname> or
	  <varname>is-expired</varname> will only work on
	  <emphasis>validated</emphasis> keys, which is why, by
	  default, only validated keys are checked for revocation and
	  expiration, although you are free to remove these extra
	  checks.
	</para>
      </note>

      <para>
        In addition to the config keys listed above, a key filter may
        also have an <varname>id</varname> and
        <varname>match-contexts</varname>.
      </para>

      <para>
        Using the filter's <varname>id</varname>, which defaults to
        the filter's config group name if not given or empty, you can
        reference the key filter elsewhere in the configuration, &eg;
        in &kleopatra;'s View configurations<!--TODO write and
        link-->. The <varname>id</varname> is not interpreted by
        &kleopatra;, so you can use any string you like, as long as
        it's unique.
      </para>

      <para>
        The <varname>match-contexts</varname> limits the applicability
        of the filter. Two contexts are currently defined: The
        <literal>appearance</literal> context is used when defining
        coloring and font properties for the views. The
        <literal>filtering</literal> context is used to selectively
        include (and exclude) certificate from
        views. <literal>any</literal> can be used to signify all
        currently defined contexts, and is the default if
        <varname>match-contexts</varname> is not given, or otherwise
        produces no contexts. This ensures that no key filter can end
        up <quote>dead</quote>, &ie; with no contexts to apply it in.
      </para>

      <para>
        The format of the entry is a list of tokens, separated by
        non-word characters. Each of the tokens is optionally prefixed
        by an exclamation point (<literal>!</literal>), indicating negation. The tokens act
        in order on an internal list of contexts, which starts out
        empty. This is best explained by an example: <literal>any
        !apperance</literal> is the same as
        <literal>filtering</literal>, and <literal>appearance
        !appearance</literal> is producing the empty set, as is
        <literal>!any</literal>. However, the last two will be
        internally replaced by <literal>any</literal>, since they
        produce no contexts at all.
      </para>

      <para>
	In general, criteria not specified (&ie; the config entry is
	not set) are not checked for. If a criterion is given, it
	is checked for and must match for the filter as a whole to
	match, &ie; the criteria are AND'ed together.
      </para>

      <para>
        Each filter has an implied <quote>specificity</quote> that is
        used to rank all matching filters. The more specific filter
        wins over less specific ones. If two filters have the same
        specificity, the one that comes first in the config file
        wins. A filter's specificity is proportional to the number of
        critera it contains.

	<para>
	  To check for all disabled OpenPGP keys (not yet supported by &kleopatra;)
	  with ownertrust of at least
	  <quote>marginal</quote>, you would use:
	</para>
	<screen><!--
-->[Key Filter #<replaceable>n</replaceable>]
Name=disabled OpenPGP keys with marginal or better ownertrust
is-openpgp=true
is-disabled=true
is-at-least-ownertrust=marginal
