It is NOT certain that the key belongs to the person named
in the user ID.  If you *really* know what you are doing,
you may answer the next question with yes

Use this key anyway?
gpg: message.txt: encryption failed: unusable public key
[alice@client ~]$

我参考KEVIN老师的GPG实验
创建alice bob
su - alice
mkdir .gnupg
gpg --gen-key
建立了KEY
BOB同
然后

BOB下
gpg --export --armor bobby > /tmp/bob.key
输出PUB KEY

ALICE下
gpg --import /tmp/bob.key
倒入BOB的PUB KEY

echo "11111">message.txt
gpg --encrypt --armor --recipient bobby message.txt
用BOB的PUBKEY加密asd.txt
问题就出在这里了。。。。
gpg: message.txt: encryption failed: unusable public key
意思是这个PUBKEY是没用的PUBKEY。。。晕倒。。

不过第一次做我是做出来的 不过后来想脱离书本做一下就失败了
然后再看书做。。也是这样

Maybe you can try some of the gpg commands in this thread and see if that will help:
