There are two samples on our blog, and I'm adding additional samples here.

This connects to our demo server, lists the root directory contents and downloads the readme.txt file:

# load Rebex SFTP assemblies
Add-Type -Path "c:\Program Files (x86)\Rebex Components 2017 R4.1\bin\net-4.0\Rebex.Common.dll" 
Add-Type -Path "c:\Program Files (x86)\Rebex Components 2017 R4.1\bin\net-4.0\Rebex.Networking.dll" 
Add-Type -Path "c:\Program Files (x86)\Rebex Components 2017 R4.1\bin\net-4.0\Rebex.Sftp.dll" 

# create an instance of Sftp object
$sftp = New-Object Rebex.Net.Sftp

# omit this if logging is not needed (or use FileLogWriter to log into a file)
$sftp.LogWriter = New-Object Rebex.ConsoleLogWriter([Rebex.LogLevel]::Info)

# connect and authenticate
$sftp.Connect("test.rebex.net")
$sftp.Login("demo", "password") 

# display contents of the root directory (use GetList to get a parsed form)
Write-Output $sftp.GetRawList("/")

# download a file into the current directory
$sftp.Download("/readme.txt", ".")

# disconnect from the server and dispose the sftp object
$sftp.Disconnect()
$sftp.Dispose()

To authenticate using a private key instead of a password, use create an instance of SshPrivateKey and use another overload of the Login method:

...
$key = New-Object Rebex.Net.SshPrivateKey("C:\MyData\Key.ppk", "keypassword")
$sftp.Login("username", $key) 
...

And to use both a key and password, use this:

...
$key = New-Object Rebex.Net.SshPrivateKey("C:\MyData\Key.ppk", "keypassword")
$sftp.Login("username", "password", $key) 
...

Most methods of the Sftp object are simple-to-use and quite suitable to be called from PowerShell scripts - converting the sample code from our features pages should be quite simple.

Hello,

I am trying out Rebex HTTPs for our Compact Framework.Net app. The app makes extensive use of WCF calls using proxies generated by the CF.Net version of svcutil.

I am using the HttpRequestCreator.Register() approach for registering the Rebex library. However, the WCF calls are getting an error inside the HTTPChannelFactory class with an InvalidCastException. The .Net HTTPChannelFactory.GetWebRequest method is expecting the return type of GetWebRequest to be HttpWebRequest. Since Rebex returns a HttpRequest, this is resulting in the casting exception. I am adding the stack trace at the end of this message.

Is there any alternative way of using HttpChannelFactory with Rebex, or plans to add support for this in the future ?

Thanks.

Subha Tarafdar.

Hi,
I downloaded RebexHttps-2017R2-Trial.exe to support TLS 1.2 in .net CF 3.5.
I did the adjustment but cannot log into https sites. My code is given bellow.

This was an existing code and i modified it to support TLS 1.2 based on the instructions given in Rebex site. But i feel i have missed something.

Our app uses ant file patterns for selecting files, does the FileSet class support these or do we need to create our own descendent?

Looking at the help, it looks like it may do, with ** support, just wondering if it's intended to support any ant pattern?

So I know this is a pretty common problem and but it's showing itself in a very unique way. I have built a program that basically retrieves emails via IMAP and then resends them. I build the program originally in test format under a windows console program. It works perfect. I built a windows service project and have installed it successfully and have it running the code starting fine. The issue is the exact same code in windows service gives me the Object ref not set. I have tried everything that i can think of. Added right, installed the dlls in the GAC, put the files with the EXE. Below is the sample code. Any help would be greatly appreciated. The error code I'm catching is "Object reference not set to an instance of an object"

using imap As New Rebex.Net.Imap()

    Dim mydb As New mySqlDB
        mydb.executeDMLSQL("insert into o365pocdb.poc_log (server, type, data, POC) values ('"& Server & "','Perf-Log','POC Started','"& Username & "')", sresult)

        Try
            mydb.executeDMLSQL("insert into o365pocdb.poc_log (server, type, data, poc) values ('"& Server & "','error','connected fine',' ')", sresult)
            imap.Connect(hostname, SslMode.Implicit)
            imap.Login(Username, Password)
            imap.SelectFolder("Inbox")

        Catch ex As Exception
        'mydb.executeDMLSQL("insert into o365pocdb.poc_log (server, type, data, poc) values ('"& Server & "','error','"& ex.Message & "',' ')", sresult)
        mydb.executeDMLSQL("insert into o365pocdb.poc_log (server, type, data, poc) values ('"& Server & "','error','Going to exit sub - cant connct','"& ex.Message & "')", sresult)
        Exit Sub
    End Try

Hello,

I am not sure what you mean by ant file patterns other than using '**' in the path. You can use this 'wildcard' in both Include and Exclued methods, as you probably read at our file set feature page. It serves recursive search and matching file or directory deep in directory tree based at path provided to the FileSet constructor. If it doesn't suite you, you can create your own descendent, of course. How to implement it, please read this file set forum post for the start. It implements fileset based on regular expression, but you should be able to rewrite it to any ant pattern support as you need.

Hello,

How would I remove a few receive headers in an email? I can list them out fine but I can't figure out how to strip a few out. I'm a little confused as to how to leverage the removeat method of the HeaderValueCollection. Any help would be welcome.

Dim mail As MailMessage

    mail = imap.GetMailMessage(uniqID)

    For Each header In mail.Headers

            If header.Name Like "Received" Then
                If InStr(header.value.ToString, "prod.outlook.com") > 0 Then
                    MsgBox("Going to remove the header")
                    header.removeat(header)' This doesn't work
                End If

                MsgBox(header.Value.ToString)

            End If

This looks useful. However, the encryption would not be done in-place anyway (otherwise, if the app was terminated in the middle of encrypting a file, we would end up with half-encrypted file). That means that we would still have to do File.Delete(filename)+File.Move(encrypted, filename) afterwards (sadly, Windows doesn't support POSIX-like atomic rename).

We will consider this, but implanting a custom extension method for the FileEncryption class is the recommended solution for now.

We get the following errors when connecting to an SFTP server. Any ideas?

Unfortunately, there is no such feature as file priority. Sorry.

Your solution is the correct one.
If you have more .SFV files to be uploaded, you can use FileSet class to easily select them:

var sfvFiles = new FileSet("c:/data");
sfvFiles.Include("*.sfv", TraversalMode.MatchFilesDeep);

// upload all .SFV files first
client.Upload(sfvFiles, "/data");

var otherFiles = new FileSet("c:/data");
otherFiles.Include("*");
otherFiles.Exclude("*.sfv", TraversalMode.MatchFilesDeep);

// upload other files
client.Upload(otherFiles, "/data");

We send mail from two different modules. One is while configuration/setup and another is when you select the file and send mail to addresses.

Configuration is success. But actual send mail is failing.

Some server have been observed to have troubles with SMTP's "pipelining" and "chunking" extensions. Please try to disable them before calling the Send method and let us know whether this has any effect:

smtp.EnabledExtensions &= ~(SmtpExtensions.Pipelining | SmtpExtensions.Chunking);
smtp.Send(...);

Are you planning on implementing support for the Signature algorithm RSASSA-PSS (as per IETF RFC 4056)in SecureMail before the end of 2017?

This will be a mandatory requirement here in Germany as of 1st January 2018.
