As a good security practice, you should validate PGP keys you receive, and not trust keys.
You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.
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.
About Terminal
Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.
To open the macOS Terminal, follow these steps:
- In Finder, choose Utilities from the Applications folder.
- Find Terminal in the Utilities listw.
- Open Terminal.
The Terminal window opens with the commandline prompt displaying the name of your machine and your username.
Generating an SSH key
An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use
ssh-keygen
to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.To generate SSH keys in macOS, follow these steps:
- Enter the following command in the Terminal window.This starts the key generation process. When you execute this command, the
ssh-keygen
utility prompts you to indicate where to store the key. - Press the ENTER key to accept the default location. The
ssh-keygen
utility prompts you for a passphrase. - Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.
You will need to enter the passphrase a second time to continue.
After you confirm the passphrase, the system generates the key pair.
Your private key is saved to the
id_rsa
file in the .ssh
directory and is used to verify the public key you use belongs to the same Triton Compute Service account.Never share your private key with anyone! |
---|
Your public key is saved to the
id_rsa.pub
;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this: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.
Troubleshooting
You may see a password prompt like this:
This is because:
- You did not enter the correct passphrase.
- The private key on your Macintosh (
id_rsa
) does not match the public key stored with your Triton Compute Service account. - The public key was not entered correctly in your Triton account.
What are my next steps?
Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines.
In order to use the Terminal to create instances, set up
triton
and CloudAPI as well as the triton-docker
commandline tool.by Radu Raicea
Sending sensitive information through the internet is always nerve-racking. What if somebody else sees the bank information I’m sending? Or even those dank memes that should not be spoken of?
Fortunately, there’s a pretty good solution to this problem: Pretty Good Privacy (PGP).
A software engineer named Phil Zimmermann created PGP back in 1991. He was an anti-nuclear activist, and wanted a way to transfer information securely over the Internet.
Zimmermann got into trouble with the US government in 1993 because PGP travelled international waters and reached a vast number of countries around the globe, violating US export restrictions for cryptographic software.
Today, PGP is “owned” by Symantec, but OpenPGP, an e-mail encryption standard, is implemented by multiple software.
You might also hear a lot about GPG. It is another software tool that implements the OpenPGP standard.
How does PGP actually work?
PGP is very easy to understand, on the surface. Imagine you want to send your credit card information to a friend and you write it on a piece of paper. You then put the paper in a box and send it by mail.
A thief can easily steal the box and look at the paper that contains your credit card information. What could you do instead?
You decide to put a key lock on the box, but you realize that you have to send the key along with the box. That’s no good.
What if you meet your friend in person to share the key beforehand? That could work, right? It could, but then both of you have a key that allows to unlock the box. You, as the sender, will never need to open the box again after closing it. By keeping a copy of a key that can unlock the box, you are creating a vulnerability.
Finally, you found just the right solution: you’ll have two keys. The first key will only be able to lock the box. The second key will only be able to open the box. That way, only the person who needs to get the content of the box has the key that allows them to unlock it.
This is how PGP works. You have a public key (to lock/encrypt the message) and a private key (to unlock/decrypt the message). You would send the public key to all your friends so that they can encrypt sensitive messages that they want to send to you. Once you receive an encrypted message, you use your private key to decrypt it.
A Brief Example
There are plenty of software tools that implement the OpenPGP standard. They all have different ways of setting up PGP encryption. One particular tool that works very well is Apple Mail.
If you are using a Mac computer, you can download the GPGTools. This application will generate and manage your public and private keys. It also integrates automatically with Apple Mail.
Once the keys are generated, you will see a lock icon in the subject line, when composing a new message in Apple Mail. This means that the message will be encrypted with the public key you’ve generated.
After sending the e-mail to someone, it will look like this. They will not be able to see the content of the e-mail until they decrypt it using the private key.
Note that PGP encryption does not encrypt the subject line of an e-mail. Never put any sensitive information in the subject line.
If you are using software that automatically decrypts the message using your private key, like Apple Mail, it will look something like this:
