How is the private key generated by OpenSSH used in putty?

Background description

The remote office Linux springboard, the public and private keys are generated by OpenSSH that comes with MacOS.One day, I came home from get off work without a computer and only had a Windows computer at home.I just wanted to use this Windows computer to remotely go to the springboard to temporarily process the item work. Anyway, I have the private key.I temporarily downloaded putty and configured the private key, but I couldn't log in.The error is as follows:

From the prompt, it should be that putty does not support the private key format generated by openssh.No wonder when importing the private key to putty, you can see that the file format requested is .ppk (putty private key files).

How to solve it?

After querying the data, I learned that putty has its own keygen tool, which can be used to convert the private files generated by openssh into .ppk format.

putty-kengen does not have a separate installation package, the installation package in .msi format will be installed automatically.

Let's try converting the private key before logging in.

• Import the private key file generated by openssh

• Save it

• Configure putty to use the converted private key

Successful login.
