• 产生SSH秘钥

$ ssh-keygen -t rsa -C "mailwp@163.com" 
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/wupeng/.ssh/id_rsa):
Created directory '/Users/wupeng/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/wupeng/.ssh/id_rsa.
Your public key has been saved in /Users/wupeng/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:mBQBlr4W+G78Gm7tiBnq380bmF3ZCKz2DJ2RH2FKVnQ mailwp@163.com
The key's randomart image is:
