Android Question B4A SFTP Library

[Nenad Hukavec]

Hello,

I haven't needed SFTP for a long time, and now I see that Jsch library no longer works with the new version of the SFTP server due to deprecated algorithms.
Is there a newer version or some other alternative for SFTP? I can't find anything useful...

I haven't tried it myself: https://www.b4x.com/android/forum/threads/sshj-ssh-scp-sftp-for-java.88615/#content

Tnx I saw that but it's too complicated to implement in an old app built for Android 4.4.
I am looking for a library that would work like Jsch without additional dependencies.
And maybe it's time for those old devices to stop working after almost ten years!

I did try at and it crashed in the first Row

Sub DownloadFileFromSFTP(FullFilename As String, Titel As String, Aufruf As Int)
        
    Dim mSSH As SSHJ
    
    mSSH.Initialize("SSH")
    mSSH.AddHostKeyPromiscuousVerifier
    mSSH.AddAuthPassword (Starter.settings.get ("FTP.PW"))
    mSSH.Connect(Starter.settings.get ("FTP.Server") , Starter.settings.get ("FTP.Port") , Starter.settings.get ("FTP.User"))
    
    Wait For ssh_Connected (success As Boolean)
    
    If success Then
        ToastMessageShow("Die " & Titel & " werden geladen",False)
        Dim SFTP As SSHJSFTPClient = mSSH.GetSFTPClient
        Dim SF As Object = SFTP.Download(Starter.settings.get ("FTP.Folder") & "/" & FullFilename, File.DirInternal & "/" & FullFilename,False)
        wait for (SF) SFTPDownloadFinished(success As Boolean, remoteFilePath As String,LocalFilePath As String)
        If success Then
            ToastMessageShow("Die " & Titel & " wurden vom SFTP Server geladen",False)
            If Aufruf = 1 Then CreateZahlungsarten
            If Aufruf = 2 Then CreateOrganisationen
        Else
