我刚刚生成了一个新的GPG密钥对,并且gpg显示了一些随机的加号,减号,大于,小于和抑扬符。我一直想知道它们的意思。你能跟我解释一下吗?
iblue@nerdpol:~$ gpg --gen-key
[... snip ...]
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.
