If you plan on using the Oracle Cloud Services, you will need to generate some SSH Keys to enable secure access to Oracle Cloud resources from applications such as SQL Developer and even terminal connections. Below I will outline the process for creating SSH Keys on macOS.

2. Ssh Keygen On Mac

Generating an SSH key with macOS is relatively straight forward using the variety of Terminal applications available for the OS.

I have written this post as part of a prereq documentation for building on Oracle Cloud Services, but the step apply regardless of your objective. There are plenty of places documenting these steps for both Windows and Linux

Sep 26, 2019 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. Creating an SSH key on Linux & macOS 1. Check for existing SSH keys. You should check for existing SSH keys on your local computer. You can use an existing SSH key with Bitbucket Server if you want, in which case you can go straight to either SSH user keys for personal use or SSH access keys for system use. Open a terminal and run the following. Jul 19, 2018 Saving SSH keys in macOS Sierra keychain. Contribute to jirsbek/SSH-keys-in-macOS-Sierra-keychain development by creating an account on GitHub.

To open the a terminal application you can either find it in the Dock, but if it’s not there, follow these steps:

1. Click the Applications icon in the dock
2. Search for and click the Utilities folder
3. Launch the Terminal application

Once your terminal window is open, to generate the ssh key, follow these steps:

Your private key is saved as “cloudKey” and your public key is “cloudKey.pub” both in the ~/.ssh directory. Next steps will be use these files to enable secure remote access without the need to use passwords.

Once you have completed this, you can now use the generated keys to populate the SSH Key dialogue box.

Take a look at the following blog posts for examples on how you can use this to connect to the Oracle Database Cloud Service.

Enjoy!

The public RSA key components (n, e) DO get generated with and are embedded into the private RSA key file created with openssl genrsa command. A separate public key file. Generate public key from n and e. In particular, the inclusion of the public exponent e in the private key format means that the public key can be trivially extracted from a PKCS1 compliant private key file.

Problem

As described in detail on https://openradar.appspot.com/27348363, macOS/OS X till Yosemite used to remember SSH keys added by command ssh-add -K <key>.

Unfortunately this way no longer works. Keys added to the keychain via ssh-add -K are not automatically re-added to the ssh-agent after a reboot. As Apple Developer stated:

'That’s expected. We re-aligned our behavior with the mainstream OpenSSH in this area.'

Solutions

Solution 1 (recommended)

Apple updated its Technical Notes to indicate that since 10.12.2, macOS includes version 7.3p1 of OpenSSH and its new behaviors.

In ~/.ssh create config file with the following content:

Solution 2

After usage of ssh-add -K <key> (it's recommended to use absolute path of keys) call the command ssh-add -A on every startup of macOS.

To automate this, add a .plist with the following content to the path ~/Library/LaunchAgents/:

Alternatives

• Create this file with the Lingon app.

• Use curl to download the .plist file to the stated path:

Notes

Ssh Keygen On Mac

If you have issues with ssh-add: illegal option -- K after using the ssh-add -K command, you may use the full path of the command /usr/bin/ssh-add.
