HULFT Square does not support OpenSSH format private keys.
Please convert an OpenSSH format private key to a PEM format private key, or generate a new PEM format private key.

The header of a PEM format private key is "-----BEGIN RSA PRIVATE KEY-----".

For the details on how to generate a PEM format private key, see the following external document.
