Nov 29, 2017 How To: Connect via SFTP using SSH.NET. In my current project I've to connect to a remote server via Secure File Transfer Protocol (aka SFTP) using a user name, a RSA private key and a phassphrase. Once connected, the goal is to read some files from a remote folder and download them to a local folder. PuTTY-User-Key-File-2: ssh-rsa. SSH key pairs allow an additional level of security that can be used in conjunction with the SFTP protocol. Key pairs are typically created by the client, and then the resulting public key is used by Core FTP Server. Core FTP products use the OpenSSH SSH2 format, that can be generated using Core FTP software, or via the ssh-keygen utility.
This guide contains description of setting up public key authentication for use with WinSCP. You may want to learn more about public key authentication or SSH keys instead.
- Configure Server to Accept Public Key

Before starting you should:
- Have WinSCP installed;
- Know how to connect to the server without public key authentication.
If you do not have a key pair yet, start with generating new key pair.
Connect to your SSH server using WinSCP with the SSH protocol, using other means of authentication than public key, e.g. typically using password authentication.
Once logged in, configure your server to accept your public key. That varies with SSH server software being used. The most common SSH server is OpenSSH.
You can use Session > Install Public Key into Server command on the main window, or Tools > Install Public Key into Server command on SSH > Authentication page page on Advanced Site Settings dialog. The functionality of the command is similar to that of OpenSSH ssh-copy-id
command.
Or you can configure the key manually:
- Navigate into a
.ssh
subdirectory of your account home directory. You may need to enable showing hidden files to see the directory. If the directory does not exists, you need to create it first. - Once there, open a file
authorized_keys
for editing. Again you may have to create this file, if this is your first key. - Switch to the PuTTYgen window, select all of the text in the Public key for pasting into OpenSSH authorized_keys file box, and copy it to the clipboard (
Ctrl+C
). Then, switch back to the editor and insert the data into the open file, making sure it ends up all on one line. Save the file. WinSCP can show you the public key too. - Ensure that your account home directory, your
.ssh
directory and fileauthorized_keys
are not group-writable or world-writable. Recommended permissions for.ssh
directory are700
. Recommended permissions forauthorized_keys
files are600
. Read more about changing permissions.
- Save a public key file from PuTTYgen, and copy that into the
.ssh2
subdirectory of your account home directory. - In the same subdirectory, edit (or create) a file called
authorization
. In this file you should put a line likeKey mykey.pub
, withmykey.pub
replaced by the name of your key file.
For other SSH server software, you should refer to the manual for that server.
When configuring session, specify path to your private key on SSH > Authentication page of Advanced Site Settings dialog.
Alternatively, load the private key into Pageant.
Cloud providers have typically their own mechanism to setup a public key authentication to virtual servers running in the cloud.

- Amazon EC2;
- Google Compute Engine;

Secure Shell (SSH) allows you to remotely administer and configure your Windows IoT Core device
Using the Windows 10 OpenSSH client
Core Ftp Generate Ssh Key Password
Important
The Windows OpenSSH client requires that your SSH client host OS is Windows 10 version 1803(17134). Also, the Windows 10 IoT Core device must be running RS5 Windows Insider Preview release 17723 or greater.
The OpenSSH Client was added to Windows 10 in 1803 (build 17134) as an optional feature. To install the client you can search for Manage Optional Features in Windows 10 settings. If the OpenSSH Client is not listed in the list of installed features then choose Add a feature.
Next select OpenSSH Client in the list and click Install.
To login with a username and password use the following command:
Where host is either the IP address of the Windows IoT Core device or the device name.
The first time you connect you see a message like the following:
Type yes and press enter. Microsoft office professional plus 2013 product key generator download.
If you need to log in as DefaultAccount rather than as administrator you will need to generate a key and use the key to log in. From the desktop that you intend to connect to your IoT Device from, open a powershell window and change to your personal data folder (e.g cd ~)
Register the key with ssh-agent (optional, for single sign-on experience). Note that ssh-add must be performed from a folder that is ACL'd to you as the signed-in user (BuiltinAdministrators and the NT_AUTHORITYSystem user are also ok). By default cd ~ from powershell should be sufficient as shown below.
Tip
If you receive a message that the ssh-agent service is disabled you can enable it with sc.exe config ssh-agent start=auto
To enable single sign append the public key to the Windows IoT Core device authorized_keys file. Or if you only have one key you copy the public key file to the remote authorized_keys file.
If the key is not registered with ssh-agent it must be specified on the command line to login:
If the private key is registered with ssh-agent then you only need to specify DefaultAccount@host:
To enable single sign append the public key to the Windows IoT Core device authorized_keys file. Or if you only have one key you copy the public key file to the remote authorized_keys file.
If the key is not registered with ssh-agent it must be specified on the command line to login:
If the private key is registered with ssh-agent then you only need to specify DefaultAccount@host:
The first time you connect you see a message like the following:
Type yes and press enter.
You should now be connected as DefaultAccount
To use single sign-on with the administrator account, append your public key to c:dataProgramDatasshadministrators_authorized_keys on the Windows IoT Core device.
You will also need to set the ACL for administrators_authorized_keys to match the ACL of ssh_host_dsa_key in the same directory.
To set the ACL using powershell
Note
If you see a REMOTE HOST IDENTIFICATION CHANGED message after making changes to the Windows 10 IoT Core device, then edit C:Users.sshknown_hosts and remove the host that has changed.

Using PuTTY
Download a SSH client
In order to connect to your device using SSH, you'll first need to download a SSH client, such as PuTTY.
Connect to your device
In order to connect to your device, you need to first get the IP address of the device. After booting your Windows IoT Core device, an IP address will be shown on the screen attached to the device:
https://dispacapan1973.mystrikingly.com/blog/add-a-blog-post-title. Now launch PuTTY and enter the IP address in the
Host Name
text box and make sure theSSH
radio button is selected. Then clickOpen
.If you're connecting to your device for the first time from your computer, you may see the following security alert. Just click
Yes
to continue.If the connection was successful, you should see
login as:
on the screen, prompting you to login.
EnterAdministrator
and press enter. Then enter the default passwordp@ssw0rd
as the password and press enter.If you were able to login successfully, you should see something like this:
Update account password
Generate Ssh Keys Windows 10
It is highly recommended that you update the default password for the Administrator account.
To do this, enter the following command in the PuTTY console, replacing [new password]
with a strong password:
Core Ftp Generate Ssh Key For Git
Configure your Windows IoT Core device
To be able to deploy applications from Visual Studio 2017, you will need to make sure the Visual Studio Remote Debugger is running on your Windows IoT Core device. The remote debugger should launch automatically at machine boot time. To double check, use the tlist command to list all the running processes from powershell. There should be two instances of msvsmon.exe running on the device.
It is possible for the Visual Studio Remote Debugger to time out after long periods of inactivity. If Visual Studio cannot connect to your Windows IoT Core device, try rebooting the device.
If you want, you can also rename your device. To change the 'computer name', use the
setcomputername
utility:You will need to reboot the device for the change to take effect. You can use the
shutdown
command as follows:
