General information

The Secure File Transfer Protocol (SFTP client) provides secure file transfer functionality over any reliable data stream, SSH in this case. It is the standard file transfer protocol for use with the SSH2 protocol. Windowless wodSFTP component implements client side of this protocol which is reliable and easy to use. SFTP is supported by all SSH2 servers as their subsystem.

Usage model

SFTP protocol is designed to provide primarily file transfer, but also more general file system access on the remote server - in secure manner. SFTP protocol assumes it is running on secure channel (secure channel is implemented in wodSFTP), thus no plaintext passwords, file or directory contents, or any other information is exposed to the network.

Features include

most important PutFile (for file uploading) and GetFile (for file downloading) methods, but also

  • PutData and GetData to copy string variable to/from remotefile,
  • PutFiles, GetFiles... to upload/download/delete multiple files, recursively
  • Direct read/write on remote file with RemoteOpen, RemoteRead, RemoteWrite and RemoteClose methods
  • MakeDir and RemoveDir to create and delete directories,
  • DeleteFile to delete file on the server,
  • ListItems event to list files in some directory on remote server,
  • GetAttributes/SetAttributes to retrieve and set attributes for the file (or directory),
  • Resume property to resume broken transfers,
  • Blocking mode to execute methods and wait until they are completed.
  • Password and PublicKey properties that determine type of authentication with the server
  • ASCII and Binary file transfers to handle different data types....
  • Done event that is fired when executed method is completed - a perfect place to initiate new command...
  • Compression - from 0 (no compression) up to level 9 (high compression)
  • Proxy support - for SOCKS4/5 and standard WEB proxy
  • Password and PrivateKey authentication
  • fast notifications - you can use callback methods, not slow events
  • Support for 64-bit file sizes (more than 4.2gb)

Ideal in many environments

Due to it's support both for blocking mode and asynchronous mode, wodSFTP can be used in many environments, such as VB (most popular), Delphi, VC, but also in ASP, VBS.

wodSFTP is tested and works great with all OpenSSH versions, as well as SSH (from SSH Communications Security Corp.) which are most common on todays servers, but has been also tested on others too. Different server implementations handle some sftp features differently (for example, some add / to the end of each directory name) but wodSFTP has no problems with those. If there is a problem - we will fix it or add certain feature on your request.

Provided samples will guide you how to take full power of our best selling component.
