What is the Difference Between Implicit and Explicit SSL?
The difference between explicit and implicit TLS/SSL are in the details of the connection. The differences can be summarized as follows: With explicit TLS/SSL, your FTP client specifically asks for an encrypted connection. With implicit TLS/SSL, a secure connection is implied by connecting to a specific port on the FTP server. Explicit TLS/SSL allows your FTP client to negotiate security with the server. Implicit TLS/SSL does not allow negotiation. Explicit TLS/SSL is more secure as it allows the FTP client to reject bogus SSL certificates. Implicit TLS/SSL was not defined in RFC 4217, and is therefore deprecated. ExaVault only supports FTP over Explicit SSL. Because Implicit SSL is not part of the official standard, we do not plan to support it. For further details about the nature of FTP-SSL connections, visit the Wikipedia page for FTP-SSL.
