Always resolves the server hostname by performing a DNS query. This means a DNS query will be done when using any proxy as well.

Forces listing date format on AS/400 like systems. Format is 'DMY' for day,month,year; 'MDY' for month, day, year; and so on.

Gets or sets a value that indicates whether the backslash '\' is remote directory separator when working with paths (in addition to slash '/').

Gets or sets the compression level used when uploading in mode Z (Zlib). Possible values are 0-9, where 0 means no compression (fastest) and 9 means best compression (slowest). Default value is 6 (medium compression and speed).

Makes the passive mode transfer initialize the connection only after the LIST/NLST/RETR/STOR command has been sent.

Gets or sets a value indicating whether to automatically issue `SITE NAMEFMT 1` command when AS/400 system is detected in a batch operation such as Download(String, String, TraversalMode) or Upload(String, String, TraversalMode). Default is false, which means the `SITE NAMEFMT 1` is issued.

Disables a workaround for FTP servers that announce private range IP addresses even though a public IP was used to connect to them. By default, when such server is detected, an IP address announced by the server in response to PASV command used is overrode with an IP used by the control connection.

Disables progress percentage reporting through TransferProgressChanged event.

Disables feature detection using FEAT and other commands.

Do not send the ABOR command when aborting download.

Do not send abort signals when aborting download.

Gets or sets a value that indicates whether to enable a workaround for FTP/SSL servers which do not handle TLS 1.3 shutdown properly.

Enables reading and throwing out any unexpected incoming responses when sending an FTP command.

Gets or sets a value that indicates whether to use RNFR/RNTO commands to determine remote file existence. Only supported for Windows CE FTP server.

Gets or sets a value indicating whether to attempt to negotiate extended MLST/MLSD facts using OPTS MLST command.

Some firewalls and some versions of ActiveSync were observed not to close data connections properly, causing '426' server errors. This option enables a workaround for this.

Makes it possible to call multiple methods from different threads at once. The calls will block until the operation is completed.

Forces the CCC command behavior that was used by older Rebex FTP/SSL releases.

Gets or sets a value indicating whether to use EPSV/EPRT commands to initiate a data channel.

Use "LIST -la" instead of "LIST" in GetList()()()()/GetRawList()()()() methods.

Forces MDTM command to be always used by GetFileDateTime(String) instead of MLST (which is used when available by default).

Specifies whether to just use a combination of PWD and CWD commands when determining remote directory existence.

Overrides an IP address announced by the server in response to PASV command with an IP used by the control connection.

Send NOOP command during file transfers every 10 minutes.

Gets or sets the length of interval (in seconds) between NOOP commands sent during transfer when the KeepAliveDuringTransfer option is enabled.

Gets or sets a time offset, which is added to date/time value when sending MDTM command to the FTP server. If this offset is set, other workarounds for MDTM command are disabled.

Gets or sets the default processing mode of detected links in multi-file operations.

Gets or sets the default move behavior in multi-file transfers.

Performs a small pause before closing the encrypted upload connection when the transfer is finished. Used as a workaround for servers that are unable to correctly handle the last block data if it is followed by a TLS CloseNotify message in the same TCP block.

Gets or sets a checksum type to be preferred in multi-file operations when FTP server supports several checksum types.
Default value: SHA1.

In multi-file operations it forces checking, whether currently processing item still exists.

Gets or sets a value that indicates which date/time is restored after successful transfer if possible. Please note that FTP protocol supports LastWriteTime only (CreationTime and LastAccessTime are not supported).

Re-use control connection session ID for data connections.

Deprecated. Doesn't have any effect now.

Gets or sets a value that indicates whether to skip duplicate items in directory listings or whether to fail.

Specifies whether to accept all server certificates by default. This is strongly discouraged in production environment.

Gets or sets the group of allowed elliptic curves (for ECDHE cipher suites).

Gets or sets the group of allowed TLS/SSL cipher suites.

Gets or sets allowed TLS/SSL versions.

Gets or sets a value indicating whether vulnerable ciphers might be enabled using SslAllowedSuites property.

Gets or sets TLS/SSL client certificate request handler.

Do not send empty record after successful handshake with CBC ciphers.

Gets or sets the minimum allowed size (in bits) of the ephemeral Diffie-Hellman prime. Valid values are from 512 to 16384, inclusive.

Gets or sets the preferred signature hash algorithm.

Enables and disables renegotiation indication extension.

Gets or sets a value indicating whether to reuse TLS/SSL sessions for data transfers. Default value is true.

Gets or sets validation options to use when validating a server certificate using the default certificate validator. This value is passed as Options as well.

Gets or sets TLS/SSL server certificate verifier.

Gets or sets TLS/SSL server's common name.

Enables and disables server name indication.

Gets or sets a TLS/SSL session to resume.

Gets or sets a key usage check mode for server certificate.

Gets or sets the type of TLS/SSL initialization for explicit TLS/SSL mode.

Gets or sets a value which specifies granularity for time comparisons.

Makes Timeout property affect asynchronous methods as well. By default, it only affects the synchronous methods.

Specifies FTP command for uploading files. STOR is used by default.

Specifies whether to use old API style paths (relative) or new API style paths (absolute) in multi-file transfers.
