When you try to import a key pair that you created using puttygen.exe on the management console, the system displays a message indicating that the import failed.
The format of the public key content does not meet system requirements.
If you store a public key by clicking Save public key on PuTTY Key Generator, the format of the public key content will change. You cannot import the key on the management console.
Use the locally stored private key and PuTTY Key Generator to restore the format of the public key content. Then, import the public key to the management console.
The system automatically loads the private key and restores the format of the public key content in PuTTY Key Generator. The content in the red box in Figure 2 is the public key whose format meets system requirements.
