+
+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)
+Your selection? 1
+RSA keys may be between 1024 and 4096 bits long.
+What keysize do you want? (2048) 
+
+Requested keysize is 2048 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) 
+
+Key does not expire at all
+Is this correct? (y/N) y
+
+You need a user ID to identify your key; the software constructs the user ID
+from the Real Name, Comment and Email Address in this form:
+    "Heinrich Heine (Der Dichter) <heinrichh@duesseldorf.de>"

+Real name: NIIBE Yutaka

+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.
