We recently changed over to use SFTP instead of FTP with exact targets import/export FTP server.
When we try to log in with our existing FTP credentials, it says wrong authentication method, expecting publickey, and so on.
I've generated some keys using puttygen, however when I tried to upload them using asymmetric key in Encryption Key management, it says that it's an invalid key file.
Any idea how I'm supposed to get the public key for our SFTP?
