| - | The %%SSL%% is disabled by default to protect you from its known serious vulnerabilities. Enable is only, if the server does not support %%TLS%%. You may want to restrict minimum %%TLS%% version further, in order to prevent WinSCP from using versions of %%TLS%% protocol that suffer from known vulnerabilities (currently %%TLS%% 1.0). | + | The %%TLS%% 1.0 and 1.1 are disabled by default, to protect you from their known serious vulnerabilities. Enable them only, if the server does not support newer versions.((Enabling %%TLS%% 1.0 a 1.1 has an additional side effect of lowering OpenSSL security level. That allows use of insecure keys even with higher protocol versions.)) You may want to restrict minimum %%TLS%% version further, in order to prevent WinSCP from using versions of %%TLS%% protocol that may become weak or insecure in the future. The insecure SSL protocol of any version is not supported. |
| - | You may want to restrict maximum %%TLS/SSL%% version, when there is an interoperability problem with your server. Particularly %%TLS%% 1.1 and %%TLS%% 1.2 are new and some servers do not implement them correctly. | + | You may want to restrict maximum %%TLS%% version, when there is an interoperability problem with your server.
