GnuPG高级指导（4）加密分发我的私钥

私钥,需要绝密,绝对不让别人知道! 所以,分发私钥,可以加密一下! 1 给debian8加密一份“我的私钥” opensuse13:~ # opensuse13:~ # opensuse13:~ # gpg -a -r "debian8" -o FranklinYang.rsa.sec.key.debian8.asc --encrypt FranklinYang.rsa.sec.key gpg: C1845DA4: There is no assurance this key belo

GnuPG高级指导（3）导出私钥

1 为什么要导出分发私钥友情提示:分发私钥,是危险的! 我有好几个电脑,只想用一对密钥:也就是说我需要把我的私钥,放到那几个电脑上.这样,我就就可以在任意电脑上,解密和签名以及其他. 1 怎么做使用(临时)公钥把私钥加密,然后传到我的其他某个电脑,再解密. 3 我的debian8,生成(临时)密钥 [email protected]:~# gpg -K [email protected]:~# gpg -k /root/.gnupg/pubring.gpg -----------
