Component that provides implementation of SFTP (secure file transfer on SSH) protocol. Use it to transfer your file securely over encrypted network layer (using SSH2 protocol). SFTP is not just simple "FTP over SSH" wrapper - it is a newer protocol, supported by all SSH2 servers.
License includes one year of free updates and unlimited lifetime technical support. Each developer must have his own design-time license.
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.
Licensing
Upon purchase, you have the right to distribute wodSFTP.DLL, wodSFTP.OCX and wodKeys.DLL binaries in your applications free of charge. To license your existing versions (not DEMO version!), in DLL version use LicenseKey property with the key you receive from us. In OCX version you don't need to setup your key, it will be handled by your programming environment.
As usual, wodSFTP is a royalty free component.
Additional notes
wodKeys component is included in our setup package free of charge. It can be used for private key management - to Generate new keys, Load/Save the, obtain public keys etc.. Helpfile can be found here.
We are having great success with your component ... email server that has over 750 000 mailboxes back ended by a SQL server...

Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.
