When a key pair created using puttygen.exe was imported to the management console, the system displayed a message indicating that importing the public key failed.
The format of the public key content does not meet system requirements.
Storing a public key by clicking Save public key of puttygen.exe will change the format of the public key content. Such a key cannot be imported to 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 with the format meeting system requirements.
