（在debian8上解密）
[email protected]:~# gpg -d temp_txt.log.gpg
You need a passphrase to unlock the secret key for
user: "FranklinYang (Encrypt RSA 4096) <[email protected]>"
4096-bit RSA key, ID 0A09DAC9, created 2016-11-25 (main key ID 276856F7)
gpg: encrypted with 4096-bit RSA key, ID 0A09DAC9, created 2016-11-25

Try
decrypt
on
debian
8

或者，在centos7上加密和签名，发给debian8：
[[email protected] ~]#
[[email protected] ~]#
[[email protected] ~]# cat temp.sig.log
Try

with

！
encrypt

on CENTOS7
!
sending
