掩碼說明
(2)1到8為數字掩碼攻擊
-a 3 --increment --increment-min 1–increment-max 8 ?d?d?d?d?d?d?d?d –O
?d代表數字，可以換成小寫字母?l，大寫字母?u，特殊字符?s，大小寫字母+特殊字符?a，–O表示最優化破解模式，可以加該參數，也可以不加該參數。

This means that hashcat cannot use the full parallel power of your device(s).
Hashcat is expecting at least 1978368 base words but only got 34.2% of that.
Unless you supply more work, your cracking speed will drop.
