On Windows, you can create SSH keys in many ways. This document explains how to use two SSH applications, PuTTY and Git Bash.
Key based authentication in SSH is called public key authentication. It is easy to configure by end users in the default configuration. On the other hand, security-conscious organizations need to establish clear policies for provisioning and terminating key-based access. How to set up public key authentication for OpenSSH.
Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.
PuTTY
PuTTY is an SSH client for Windows. You can use PuTTY to generate SSH keys. PuTTY is a free open-source terminal emulator that functions much like the Terminal application in macOS in a Windows environment. This section shows you how to manually generate and upload an SSH key when working with PuTTY in the Windows environment.
About PuTTY
PuTTY is an SSH client for Windows that you will use to generate your SSH keys. You can download PuTTY from www.chiark.greenend.org.uk.
When you install the PuTTY client, you also install the PuTTYgen utility. PuTTYgen is what you will use to generate your SSH key for a Windows VM.
This page gives you basic information about using PuTTY and PuTTYgen to log in to your provisioned machine. For more information on PuTTY, see the PuTTY documentation |

Generating an SSH key
To generate an SSH key with PuTTYgen, follow these steps:
- Open the PuTTYgen program.
- For Type of key to generate, select SSH-2 RSA.
- Click the Generate button.
- Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair.
- Type a passphrase in the Key passphrase field. Type the same passphrase in the Confirm passphrase field. You can use a key without a passphrase, but this is not recommended.
- Click the Save private key button to save the private key. You must save the private key. You will need it to connect to your machine.
- Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
- Right-click again in the same text field and choose Copy.
Importing your SSH key
Now you must import the copied SSH key to the portal.
- After you copy the SSH key to the clipboard, return to your account page.
- Choose to Import Public Key and paste your SSH key into the Public Key field.
- In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
- Add the key. It will now appear in your table of keys under SSH.
PuTTY and OpenSSH use different formats of public SSH keys. If the text you pasted in the SSH Key starts with
—— BEGIN SSH2 PUBLIC KEY
, it is in the wrong format. Be sure to follow the instructions carefully. Your key should start with ssh-rsa AAAA…
.Once you upload your SSH key to the portal, you can connect to your virtual machine from Windows through a PuTTY session.
Git Bash
The Git installation package comes with SSH. Using Git Bash, which is the Git command line tool, you can generate SSH key pairs. Git Bash has an SSH client that enables you to connect to and interact with Triton containers on Windows.
To install Git:
- (Download and initiate the Git installer](https://git-scm.com/download/win).
- When prompted, accept the default components by clicking Next.
- Choose the default text editor. If you have Notepad++ installed, select Notepad++ and click Next.
- Select to Use Git from the Windows Command Prompt and click Next.
- Select to Use OpenSSL library and click Next.
- Select to Checkout Windows-style, commit Unix-style line endings and click Next.
- Select to Use MinTTY (The default terminal of mYSYS2) and click Next.
- Accept the default extra option configuration by clicking Install.
When the installation completes, you may need to restart Windows.
Launching GitBash
To open Git Bash, we recommend launching the application from the Windows command prompt:
- In Windows, press Start+R to launch the Run dialog.
- Type
C:Program FilesGitbinbash.exe
and press Enter.
Generating SSH keys
First, create the SSH directory and then generate the SSH key pair.
One assumption is that the Windows profile you are using is set up with administrative privileges. Given this, you will be creating the SSH directory at the root of your profile, for example:
- At the Git Bash command line, change into your root directory and type.
- Change into the .ssh directory
C:Usersjoetest.ssh
- To create the keys, type:
- When prompted for a password, type apassword to complete the process. When finished, the output looks similar to:
Uploading an SSH key
To upload the public SSH key to your Triton account:

DKIM stands for DomainKeys Identified Email. It provides a way to validate that an organization delivering an email has the right to do so.
Setting up DKIM
DKIM requires the addition of public keys into your DNS zone. The key is often provided to you by the organization that is sending your email, for example SendGrid, Postmark, or Google Apps. The key will either be inserted directly into your zone as a TXT record, or it will be a CNAME pointing to the key in your provider’s DNS.
If you’re given a string representing the DKIM, it usually looks something like this:
Insert this into a TXT record. Do this by following the instructions for creating a record, selecting TXT as the record type, and entering the string you were given into the Content field.
Your provider will also give you a specific subdomain to use, usually something like:
Enter this subdomain in the “Name” field.
If your provider gives you a fully-qualified name that ends with your domain name, DO NOT include your domain name in the “Name” field when you add the TXT record. If you’re given
pm._domainkey.yourdomain.com
, only enter pm._domainkey
in the “Name” field.Quotes and slashes?
If your provider gave you the DKIM record and it included double quotes around the record, or backslashes before semi-colons in the record, you may safely remove them. The quotes are handled automatically by our name servers, and the semi-colons will automatically be escaped if necessary.
Sometimes there will be forward slashes or other unusual characters in the DKIM record. Don’t modify those. If you have any questions or concerns, contact support.
Verifying your DKIM with dig

The dig tool is a good way to verify that your DKIM record is being returned correctly by our DNS servers.

To verify the DKIM record, query for the TXT record at the fully qualified domain name where the TXT record lives. For example, on the domain aetrion.com, you can get the TXT record using the following query:
This will return a result like this:
If no result is returned, verify that you added the TXT record with the correct subdomain. Remember the “Name” field in DNSimple should not include your domain name, otherwise you’d create a record at
subdomain.yourdomain.com.yourdomain.com
.Verifying your DKIM with an online tool

Verify your DKIM with an online tool like this one from Treehouse. This tool verifies that you have SPF and DKIM records. In the DKIM selector field, just add the first part from the subdomain your DKIM is under. For example, if your DKIM is at
google._domainkey.aetrion.com
, then the DKIM selector is “google”.Technical details
