+will not be controled by others, in some cases.
+
+** Bug fix for secp256k1 and NIST P-256.
+Bugs in basic computation were fixed.
+
+** Bug fix for bignum routines.
+Bignum routine update from upstream (failure doesn't occur for our RSA
+computation, though).  Another fix for mpi_exp_mod.

+
+Now, we have three keys (one primary key for signature and certification,
+subkey for encryption, and another subkey for authentication).
+
+
+Publishing public key
+=====================
+
+We make a file for the public key by ``--export`` option of GnuPG. ::
+
+  $ gpg --armor --output <YOUR-KEY>.asc --export <YOUR-KEY-ID>
+
+We can publish the file by web server.  Or we can publish the key
+to a keyserver, by invoking GnuPG with ``--send-keys`` option.  ::
+
+  $ gpg --keyserver pool.sks-keyservers.net --send-keys <YOUR-KEY-ID>
+
+Here, pool.sks-keyservers.net is a keyserver, which is widely used.
+
+
+Backup the private key
+======================
+
+There are some ways to back up private key, such that backup .gnupg
+directory entirely, or use of paperkey, etc.
+Here, we describe backup by ASCII file.
+ASCII file is good, because it has less risk on transfer.
+Binary file has a risk to be modified on transfer.
+
+Note that the key on host PC is protected by passphrase (which
+is <PASSWORD-KEY-ON-PC> in the example above).  Using the key
+from the backup needs this passphrase.  It is common that
+people will forget passphrase for backup.  Never forget it.
+You have been warned.
+
+To make ASCII backup for private key,
+invokde GnuPG with ``--armor`` option and ``--export-secret-keys``
+specifying the key identifier. ::
+
+  $ gpg --armor --output <YOUR-SECRET>.asc --export-secret-keys <YOUR-KEY-ID>
+
+From the backup,
+we can recover privet key by invoking GnuPG with ``--import`` option. ::
+
+  $ gpg --import <YOUR-SECRET>.asc
+
+
+Generating ECC keys on host PC
+==============================
+
+Here is an example session log to create newer ECC keys.  You need
+libgcrypt 1.7 or newer and GnuPG 2.1.8 or newer.
+
+Next, we invoke gpg frontend with ``--expert`` and ``--full-gen-key`` option. ::
+
+    $ gpg --expert --full-gen-key
+    gpg (GnuPG) 2.1.13; Copyright (C) 2016 Free Software Foundation, Inc.
+    This is free software: you are free to change and redistribute it.
+    There is NO WARRANTY, to the extent permitted by law.
+
+Then, we input ``9`` to select ECC primary key and ECC encryption subkey. ::
+    
+    Please select what kind of key you want:
+       (1) RSA and RSA (default)
+       (2) DSA and Elgamal
+       (3) DSA (sign only)
+       (4) RSA (sign only)

+       (9) ECC and ECC
+      (10) ECC (sign only)
+      (11) ECC (set your own capabilities)
+    Your selection? 9
+
+Next is the important selection.  We input ``1`` to select "Curve25519". ::
+
+    Please select which elliptic curve you want:
+       (1) Curve 25519
+       (2) NIST P-256

+
+You may see WARNING (it depends on version of GnuPG) and may been asked.  Since it is what you want, please answer with 'y'. ::
+
+    gpg: WARNING: Curve25519 is not yet part of the OpenPGP standard.

+

+

+
+    GnuPG needs to construct a user ID to identify your key.

 Let gpg-agent manage SSH key
 ============================

-I deactivate seahorse-agent.  Also, for GNOME 2, I deactivate gnome-keyring managing SSH key. ::
-
-  $ gconftool-2 --type bool --set /apps/gnome-keyring/daemon-components/ssh false
-
-I edit the file /etc/X11/Xsession.options and comment out use-ssh-agent line.
-
-Then, I create ``.gnupg/gpg-agent.conf`` file with the following content. ::
+I create ``.gnupg/gpg-agent.conf`` file with the following content. ::

  enable-ssh-support

+I edit the file /etc/X11/Xsession.options and comment out use-ssh-agent line,
+so that Xsession doesn't invoke original ssh-agent.  We use gpg-agent as ssh-agent.
+
+In the files /etc/xdg/autostart/gnome-keyring-ssh.desktop,
+I have a line something like: ::
+
+    OnlyShowIn=GNOME;Unity;MATE;
+
+I edit this line to: ::
+
+    OnlyShowIn=
+
+So that no desktop environment enables gnome-keyring for ssh.
