Computing Memo of 2003/08/18

% pgpk -g
Cannot open configuration file /home/yuuji/.pgp/pgp.cfg
Choose the type of your public key:
  1)  DSS/Diffie-Hellman - New algorithm for 5.0 (default)
  2)  RSA
Choose 1 or 2: 1

Pick your public/private keypair key size:
(Sizes are Diffie-Hellman/DSS; Read the user's guide for more information)
 1)   768/768  bits- Commercial grade, probably not currently breakable
 2)  1024/1024 bits- High commercial grade, secure for many years
 3)  2048/1024 bits- "Military" grade, secure for forseeable future(default)
 4)  3072/1024 bits- Archival grade, slow, highest security
Choose 1, 2, 3 or 4, or enter desired number of Diffie-Hellman bits
(768 - 4096): 2

You need a user ID for your public key.  The desired form for this
user ID is your FULL name, followed by your E-mail address enclosed in
<angle brackets>, if you have an E-mail address.  For example:
  Joe Smith <user@domain.com>
If you violate this standard, you will lose much of the benefits of
PGP 5.0's keyserver and email integration.

Enter a user ID for your public key:

この user ID の部分には自分のローマ字氏名とメイルアドレスを
NANASHINO Gombei <nanashi@example.net>
のように入れる(推奨)。てことで、

Enter a user ID for your public key: YAMADA Taro <taro@example.com>

Enter the validity period of your key in days from 0 - 999
0 is forever (and the default): 0

You need a pass phrase to protect your private key(s).
Your pass phrase can be any sentence or phrase and may have many
words, spaces, punctuation, or any other printable characters.
Enter pass phrase:

はい、ここが重要。ぜええええええええーーったいに誰にもばれない長いパスワード、つまりパスフレーズを考えて入力する。英語やローマ字の文章を20文字以上で考えて入力すべし。

Enter pass phrase: 長いパスフレーズを入れる
Enter again, for confirmation:
Enter pass phrase: 同じパスフレーズをもう一度入れる

We need to generate 299 random bits.  This is done by reading
/dev/random.  Depending on your system, you may be able
to speed this process by typing on your keyboard and/or moving your mouse.

はい、これで鍵のでき上がり。上記の例では自分の user ID が YAMADA Taro <taro@example.com> なのだが、以下の場合、user ID の一部にマッチするものを指定すれば良いので taro だけで指定することにする。
