| This warns you that the first available encryption is not a very secure one. Typically you would put the //warn below here// line between the encryptions you consider secure and the ones you consider substandard. By default, WinSCP supplies a preference order intended to reflect a reasonable preference in terms of security and speed. | This warns you that the first available encryption is not a very secure one.

| - | In SSH2, the encryption algorithm is negotiated independently for each direction of the connection, although WinSCP does not support separate configuration of the preference orders. As a result you may get two warnings similar to the one above, possibly with different encryptions. | + | In SSH2, the encryption algorithm is negotiated independently for each direction of the connection, although WinSCP does not support separate configuration of the preference orders.

| - | Single-DES is not recommended in the SSH2 draft protocol standards, but one or two server implementations do support it. WinSCP can use single-DES to interoperate with these servers if you enable the //Enable legacy use of single-DES in SSH 2// option; by default this is disabled and WinSCP will stick to recommended ciphers. | + | |
