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
2.詢問密鑰對位數，預設為2048，本例中手動輸入1024.
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 1024
提示輸入密鑰對有效期，輸入“0”(永不過期)并按Enter鍵确定。
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
提示将永不過期，輸入“y”确認。
Key does not expire at all
Is this correct? (y/N) y
輸入密鑰對名稱（本例中為cheshi）。
GnuPG needs to construct a user ID to identify your key.
Real name: cheshi
依次輸入郵件位址和備注。
Real name: cheshi
Email address: [email protected]
Comment: NA
You selected this USER-ID:
"cheshi (NA) <[email protected]>"
詢問是否修改或者确認，直接輸入“o”确認。
Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? o
提示您需要設定私鑰。

系統需要時間生成密鑰對，期間最好随機輸入字元或移動滑鼠等，有助于生成密鑰對，結果如下圖。
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.
