32 <para>The <application>GnuPG</application> package is GNU's tool for
33 secure communication and data storage. It can be used to encrypt data and
34 to create digital signatures. It includes an advanced key management
35 facility and is compliant with the proposed OpenPGP Internet standard as
36 described in RFC2440 and the S/MIME standard as described by several RFCs.
37 GnuPG 2 is the stable version of GnuPG integrating support for OpenPGP and
38 S/MIME.</para>

106 <warning>
107 <para>
108 If you are upgrading from gnupg prior to version 2.1, upstream
109 developers recommend to backup
110 <filename class="directory">~/.gnupg</filename>, because some additional
111 configuration will probably be necessary, and you could lose your keys.
112 You can find instructions at
113 <ulink url="http://jo-ke.name/wp/?p=111"></ulink> and
114 <ulink url="https://wiki.archlinux.org/index.php/GnuPG#.22Lost.22_keys.2C_upgrading_to_gnupg_version_2.1"></ulink>.
115 </para>
116 </warning>
117
118 <para>If the top directory path where the source is unpacked contains
119 symbolic links, the openpgp tests may fail. If this is your case and
120 you wish to run the test suite, fix that with:</para>
121
122<screen><userinput>sed -e '/noinst_SCRIPTS = gpg-zip/c sbin_SCRIPTS += gpg-zip' \
123 -i tools/Makefile.in</userinput></screen>
