【记录】SecureCRT使用pem文件通过SSH登录远程服务器
期间，需要去学习使用ssh-keygen

其中的：
- ssh-keygen -p -f runningfast_aws_test.pem
- 对于提示empty for no passphrase时，先后两次回车即可
- -p指的是：要求改变某私钥文件的密语而不重建私钥。程序将提示输入私钥文件名、原来的密语、以及两次输入新密语。
- ssh-keygen -e -f runningfast_aws_test.pem > runningfast_aws_test.pem.pub
- -e 读取OpenSSH的私钥或公钥文件，并以 RFC 4716 SSH 公钥文件格式在 stdout 上显示出来。该选项能够为多种商业版本的 SSH 输出密钥。
