Generate Public Key From Pem Mac Os

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.

Generate Public Key From Pem Mac Os Free

Run it on your local computer to generate a 2048-bit RSA key pair, which is fine for most uses. Ssh-keygen The utility prompts you to select a location for the keys. By default, the keys are stored in the /.ssh directory with the filenames idrsa for the private key and idrsa.pub for the public key. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the /.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten.

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.
Generate

You will need to enter the passphrase a second time to continue.

Adobe animate cc key generator. 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.

Key
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.

  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.

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.

Step 1: Verify that you have openssl installed.

If not, install openssl using:

If you are using Microsoft(r) Windows, checkout http://gnuwin32.sourceforge.net/packages/openssl.htm for details about the openssl package on Windows.

If you using Linux, you can use the default package manager to get the openssl package installed on your box. For example:

Step 2: Create a RSA private key.

server.key is a PEM RSA private key. To know more about what is a PEM file and it’s significance, read What is a Pem file and how does it differ from other OpenSSL Generated Key File Formats? at serverfault.com.

Step 3: Create the Certificate Signing Request (CSR) utilizing the RSA private key we generated in the last step.

The ‘challenge password’ is used by the Certificate Authority (CA) to authenticate the certificate owner when they have to revoke the certificate. There is no way to revoke a Self-Signed Certificate via Certificate Revocation List (CRL) (refer: https://devcenter.heroku.com/articles/ssl-certificate-self#generate-private-key-and-certificate-signing-request]

As a result of executing the above command, you will find a file named server.csr (‘csr’ stands for Certificate Signing Request) in the same directory.

Step 4: Generate a file named, v3.ext with the below listed contents:

This step is required because when you load the certificate in the Chrome browser, it would display an error portrayed in the below screenshot.

Setting the DNS.1 value in v3.ext file to be same as the Common Name that you mentioned while generating the certificate signing request would resolve the error. Refer https://stackoverflow.com/questions/43665243/chrome-invalid-self-signed-ssl-cert-subject-alternative-name-missing for more details about the subject alternate name missing error and the solution.

  1. Create the SSL Certificate utilizing the CSR created in the last step.

The above command will use the Certificate Signing Request and the RSA Private Key that we generated as part of executing the previous steps and generate a Certificate file named, server.crt (‘crt’ is an abbreviation of ‘Certificate’) and place it in the same directory.

Step 5: Import the newly generated certificate in your Keychain (Mac OSX only).

Since this is a self-signed certificate, the browser would display a warning mentioning that the certificate is self-signed and the website should not be trusted as portrayed in the below-listed screenshot captured on the Chrome browser.

Click the Advanced hyperlink at the bottom of the warning page and click Proceed to hyperlink.

The browser will allow you to proceed and open the homepage but will mark the site as Not-Secure as portrayed in the image below.

To avoid this accepting the self-signed certificate everytime you restart chrome or restart your web server, follow the steps outlined at Google Chrome, Mac OS X and Self-Signed SSL Certificates to add the certificate to your Mac OSX Keychain. Restart Chrome.

Other platforms like Microsoft(r) Windows and Linux have similar techniques to import a certificate into a browser. A quick Google(r) search should be able to provide you with the exact steps based on the browser that you use.

Now Chrome should happily display the green ‘Secure’ icon against the URL when you navigate to your locally deployed website. Also, the Security tab within the Developer Tools should list the site as ‘Secure’ as portrayed in the screenshot below.
