ssh-genkey 生成ssh 1 ssh 2 的 keys

man ssh-keygen

ssh-keygen generates, manages and converts authentication keys for ssh(1).  ssh-keygen can create RSA keys for use by SSH protocol version 1 and RSA or

     DSA keys for use by SSH protocol version 2.  The type of key to be generated is specified with the -t option.  If invoked without any arguments,

     ssh-keygen will generate an RSA key for use in SSH protocol 2 connections.

 -t type

             Specifies the type of key to create.  The possible values are "rsa1" for protocol version 1 and "rsa" or "dsa" for protocol version 2.

所以生成ssh1 key ,运行 ssh-keygen -t rsa1

ssh2 key 默认就可以。
