MacOSX; How To Generate 4096 bit Secure Ssh Key with Ssh Keygen. Generate 4098 Bit Key Generate 4096 Bit DSA Key. RSA is very old and popular asymmetric encryption algorithm. It is used most of the systems by default. There are some alternatives to RSA like DSA. We can not generate 4096 bit DSA keys because it algorithm do not supports. To use -c, the keys have to be already present. Excerpt of man ssh-keygen: Requests changing the comment in the private and public key files. This operation is only supported for RSA1 keys. The program will prompt for the file containing the private keys, for the passphrase if the key has one, and for the new comment. Sep 09, 2019  How to configure passwordless login in Mac OS X and Linux. Generate an RSA private key using ssh-keygen (unless you have already created one). If you’re using Linux or Mac OS X, open your terminal and run the following command under your username: local$ ssh-keygen -t rsa. Learn how to create an SSH key pair on Mac, Windows, and Linux. Open Terminal. Use the following command: ssh-keygen -t rsa -b 4096 -C 'your GitHub email address' For example: ssh-keygen -t rsa -b 4096 -C '[email protected]' When the program asks you to enter a file in which to save the key choose a unique file name.

However, you can follow the same process to use a private key when using any terminal software on Linux. Note: For information about using Secure Shell (SSH) private keys on Microsoft® Windows® operating systems, see Logging in with an SSH Private Key on Windows and Generate RSA keys with SSH by using PuTTYgen.

This will step you through the process of generating a SSH keypair on Mac OS X. Begin by opening your Terminal, generally found in the 'Utilities' subdirectory of your 'Applications' directory.

Generating a keypair

Before you generate your keypair, come up with a passphrase. The rules for good passwords also apply here: mix of upper and lower case, numbers, spaces and punctuation. Limit it to less than 31 characters.

Now, generate your keypair! Enter the following:

$ ssh-keygen -t rsa -C '[email protected]'

Note: Do not type the dollar sign above; it is an example of the default command prompt shown by Mac OS X. Your actual prompt may be different. In the example above and below, the actual part you should type is the part that follows the dollar sign.

Your terminal should respond:

Press Return to accept the default value. Your terminal should respond:

Enter passphrase (empty for no passphrase):

Enter the passphrase you decided on above. The response will be:

Enter same passphrase again:

Enter the passphrase again and press Return. The program will think a bit, and respond with something like this. Note that many of the details in the example below are just for example purposes; much of the actual output you see will differ from the below.

How do I copy my public key into my Mac's clipboard?

You can use the pbcopy utility to easily insert your public key (or other text files) into your Mac's clipboard so that you can add it to your Drupal.org profile, GitHub, or other places. The filename should be yourfilename.pub - with yourfilename being the filename you entered when you first created this file. If you just hit enter, the default is id_rsa.pub.

$ pbcopy < ~/.ssh/id_rsa.pub

You won't see any output in the terminal, but the contents of your public key will now be in your clipboard and can be easily pasted anywhere where you can normally paste text.

In case you're curious, the pbpaste utility works the other way, allowing you to easily grab the contents of the clipboard for use in the terminal. For example, the following command will write the contents of the clipboard to a file:

$ pbpaste > ~/clipboard.text

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:

1. In Finder, choose Utilities from the Applications folder.
2. Find Terminal in the Utilities listw.
3. 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:

1. 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.

2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.

3. 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.

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.

1. After you copy the SSH key to the clipboard, return to your account page.
2. Choose to Import Public Key and paste your SSH key into the Public Key field.
3. 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.
4. 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.

Ssh Key Generation

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.
