wodSFTPdll is a client library that provides an implementation of the SFTP protocol (secure FTP over SSH). Use it to transfer your files securely over an encrypted network layer (using the SSH2 protocol). Unlike the popular ActiveX version of this control, this library is intended for VC programmers that dislike using ActiveX components in their applications. Both are based on the same code.
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 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. wodSFTPdll library implements client side of this protocol which is reliable and easy to use.
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 wodSFTPdll), thus no plaintext passwords or file information is exposed to the network.
This library implements protocol that is also used in well known SCP (Secure Copy) command on UNIX systems. Internally, SCP client opens SFTP connection with the server for file transfer (much better than calling RCP over SSH connection).
Features
wodSFTPdll supports the most important PutFile (for file uploading) and GetFile (for file downloading) methods, but also:
PutData and GetData to copy string variable to/from remote file,
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 and 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...
Supported SSH servers
wodSFTPdll is tested and works great with all OpenSSH versions, as well as SSH (from SSH Communications Security Corp.) which are the most commonly used today. It has been also tested on numerous others too. Different server implementations handle some sftp features differently (for example, some add / to the end of each directory name) but wodSFTPdll has no problems with those. If there is a problem - we will fix it or add certain feature on your request.
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.
DEMO version of this library does not allow you to change your password - it will be set to 'weonlydo' and cannot be changed. To test this library, you will have to change the password on the server. Sorry - but this is the step we had to take..
Your component works really great. With minor effort I have been able to convert my delphi application...

We have recently completed a large 1200+ location project where reliable Telnet and SSH connectivity was required. wodSSH worked flawlessly and allowed our staff to complete our project ontime and within budget.
