【GnuPG】linuxにsshして実行したgpg --gen-keyが止まる対応メモ


タイトルの通りなのですが、gpgで鍵を生成したくgpg --gen-keyを実行すると止まったようなハングしたような感じになります。







# 別のターミナルで
$ ssh [your host]

# 無駄にディスク書き込み
$ dd if=/dev/urandom of=/tmp/mass bs=1M count=16384

# gpg --gen-key が終わったら...

# でかいファイルができてしまうので削除
$ rm /tmp/mass

gpg --gen-keyのほう

# 実行

$ gpg --gen-key

   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
Your selection? 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 1024
Requested keysize is 1024 bits
Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0) 0
Key does not expire at all
Is this correct? (y/N) y

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

Real name: B-san
Email address:
Comment: create sample gpg-key
You selected this USER-ID:
    "B-san (create sample gpg-key) <>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
