I am evaluating MySQL Compare and I am trying to connect to two separate database servers over ssh using public/private key pair. When I try to do the compare, I get an error message   Cannot connect to server on HOSTNAME:   Wrong Key Format. What key format is this application looking for? In the browse dialog window to select the key it's looking for files with a ".key" extension. The private key I create using the Windows 11 Pro ssh-keygen program doesn't have any extension (i.e. id_rsa). I have also tried using Putty's putty-keygen to convert the private key to a ".ppk" format ..read more

This has been asked already a while ago. Did anyone find a solution? I've tried with a user defined as 'mysql_native_password' but with the same result. I have also checked Devarts forum and they had indeed a problem reported. So that probably means that in 'MySQL compare' an old library has been used not supporting MySQL 8.0 correctly. I've also tried to get direct support but this product is only supported via the forum. Does look to me that this tool has not a very high prio ..read more
