Introduction

BizTalk server has supported the FTP (File Transfer Protocol) adapter since its early release.

With the BizTalk 2010 release, Microsoft enhanced the existing FTP adapter to support SSL (FTPS), which encrypts the data transfers between systems. In the BizTalk 2013 release, Microsoft added SFTP (SSH File Transfer Protocol also called Secure File Transfer Protocol). This has been much anticipated over the years and it is great that a true SFTP adapter now exists with BizTalk server. In the past for one had to rely on the open source adapter developed by Blogical found on CodePlex or an adapter from commercial third parties (like /n software SFTP). Now you will have advantages of Microsoft support for out-of-the-box of SFTP adapter.

How to prepare a testing environment to communicate with the SFTP adapter?

Create a new local user Control Panel -> Administrative Tools -> Computer Management -> Local Users and Groups -> right click User -> New User-> Specify a User name and password.
Switch and Login for one time using SFTPUser to create user related folder and files.
Download Windows SFTP server tool that allows you to connect, retrieve and put files to try out the functionality of the SFTP Adapter.There are many tools For this demo I am using the following one http://dl.bitvise.com/BvSshServer-Inst.exe ,Then install it with default settings and restart your machine and make sure that Bitvise SSH Server service is started.
Download any SFTP client tool in this demo I am using the following tool http://winscp.net/download/winscp517setup.exe .Then install it with default settings and restart your machine.
Open WinSCP and enter Host Name , username and password as figure 2 then click login button then click yes in warning dialog .

Figure 2. WinSCP Login Dialog .

Now you will see the following window as Figure 3.

Figure 3. WinSCP Start-up window
Create a new Directory by selecting Files-> New -> Directory as figure 4.

Figure 4.Creating new Folder in WinSCP
In create Folder window enter folder name in this demo I named it MessageTesting and check Set permissions as figure 5.

Figure 5.Set Folder Permissions in WinSCP
Create folder IN and OUT inside folder MessageTesting same settings of Step 7 and the path for receive location should be as figure 6.

Figure 6.Path of IN Folder in WinSCP

Now we are ready to configure the BizTalk SFTP Adapter.

How to configure BizTalk SFTP Adapter?

Create a receive port I name it Rcv_SFTP then create receive location Rcv_SftpLoc then choose type of receive location to SFTP from drop down list then click Configure then change AcceptAnySSHServerHostKey property to True then fill other settings as Figure 7.
