mac下生成ssh key

ssh -v

usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
           [-D [bind_address:]port] [-E log_file] [-e escape_char]
           [-F configfile] [-I pkcs11] [-i identity_file]
           [-J [user@]host[:port]] [-L address] [-l login_name] [-m mac_spec]
           [-O ctl_cmd] [-o option] [-p port] [-Q query_option] [-R address]
           [-S ctl_path] [-W host:port] [-w local_tun[:remote_tun]]

如上显示则为已经安装了ssh（mac系统一般都会帮我们安装好）

ssh -keygen　接下来显示的信息一直enter就可以啦

会显示在 ／User／xx／.ssh/ 目录下生成两个文件id_rsa和id_rsa.pub

（1）可以在Finder中找到目录中的id_rsa.pub文件并查看key

（2）也可以直接用终端，输入open ～/.ssh就可以直接打开该目录下的文件夹
