I am trying set up SFTP (SSH) connection in PyCharm IDE and got this message:
Keypair 'file' is corrupt or has unknown format.
Only SSH2 keys in OpenSSH format or PuTTY Private Key *.ppk keys are supported.
Error message: The cipher 'aes256-cbc' is required, but it is not available.
I generated the private key using puttygen.exe key generator and it has .ppk file extension. What is wrong with the format of my private key?
