For this exercise the client system is a Chromebook, and the server system is an Ubuntu VM running on Google Compute Engine.

Boxcryptor is a great backup tool. It can upload to most cloud storage providers, and encrypts each file with a unique symmetric key. Even supports 2FA. That's where all of my file-based secrets (.ovpn files, ssh keys, etc) get backed up, with the life or death production keys (google play store, prod aws keys.

Generate ssh key

Mar 31, 2020  On Linux or macOS workstations, you can generate a key by using the ssh-keygen tool. Open a terminal on your workstation and use the ssh-keygen command to generate a new key. Specify the -C flag to add a comment with your username. Ssh-keygen -t rsa -f /.ssh/KEYFILENAME -C USERNAME where. First make sure you have a Chrome OS Device with a Test Image installed. If you are a Google partner, please contact your Google representative for Google Storage access to our builds for for automated re-imaging of your test devices via the devserver (described below). Mar 03, 2020 Register a public key. In the GCP Console, open the Manage SSH Keys page. Open Cloud Source Repositories. Click Register SSH key. The Register SSH Key dialog opens. In the Key name field, type a unique name for the key. In the Key field, copy the key string from your public key file. Click Register.

The SSH client of choice on Chrome OS devices is Secure Shell. Per its own documentation, it is possible to use public key-based authentication with the Secure Shell client. However, Secure Shell cannot generate its own keys. My goal here is to be able to SSH into a Google Compute Engine VM running Ubuntu Linux, so I generated the keypair on the target Linux VM using the browser-based SSH client offered by https://console.cloud.google.com/, and then imported them into Secure Shell on my Chromebook. This is appealing because it avoids the need to configure passwords for SSH altogether.

Security note: Generating the keypair on the target machine into which possession of that keypair authorizes access is reasonable. If an attacker already has a foothold in that system, you already lose. However, once that keypair is imported into Secure Shell on one’s client device, it can be convenient to use that key for access to other systems. Consider how much you trust the VM image where ssh-keygen executes before deciding whether to use the same keypair to authorize access to any other systems. Also consider the note about HTML5 filesystems being a relatively young technology in the above link to the Secure Shell documentation about SSH keys. A topic for another day is how to integrate with a physical hardware token like a Yubikey, so that the private SSH key is never exposed to any client device software.

This creates files gce-instance-ssh and gce-instance-ssh.pub. Need for speed hot pursuit 2010 serial key generator download. Both of these files need to be copied onto the Chromebook for importing into Secure Shell. I decided to do this using cat gce-instance-ssh and cat gce-instance-ssh.pub and then copy-pasting the contents of each. The destination was a Chrome extension that can create and edit plain text files. Secure Shell requires that both gce-instance-ssh and gce-instance-ssh.pub be available to import a keypair. I shift-clicked when selecting the files for the Import (to the right of the Identity: field in the Secure Shell connection dialog) dialog box. When selecting only the private key file, there seems to be little or no UI feedback that anything has happened at all.

If successful, the drop-down next to Identity: will have a new entry, whose name appears to be the basename of the imported key files. In this case, gce-instance-ssh.
