NEVER SHARE YOUR PRIVATE SSH KEY WITH ANYONE!


What is SSH and Why do I need it?


The need to facilitate secure communication between system operators and their respective system led to the development of SSH or Secure Shell. SSH works on the premise of challenge-response ('lock' and 'key') using public and private hash values. A user installs the private key into a private location in their user directory and presents the public key any time a console session is established. The necessary tools to generate SSH keys are already preset and virtually every modern Unix-like operating system, including Linux and MacOS X. On Windows, puttygen does the job.


The public key will always follow the following syntax:



Mac Os X Generate Ssh Key For Git

where the hash value would be the length of the cipher strength chosen at generation, usually 2048bit. That WHOLE string is what you copy into your ssh key field during VM generation.The PRIVATE key you have generated should be saved securely on your computer because it is the only credential necessary to log in to the machine; if it is compromised it can be used to gain root access to your machine which isn't good!



Deploying Python applications typically requiresSSH keys. An SSH key has both a public and a private key file. You canuse the private key to authenticate when syncing remote Gitrepositories, connect to remote servers and automateyour application's deployments viaconfiguration management tools likeAnsible. Let's learn how to generate SSH key pairs onmacOS Sierra.

Generating New Keys

Bring up a new terminal window on macOS by going into Applications/Utilitiesand opening 'Terminal'.

The ssh-keygen command provides an interactive command line interface forgenerating both the public and private keys. Invoke ssh-keygen with thefollowing -t and -b arguments to ensure we get a 4096 bit RSA key. Notethat you must use a key with 2048 or more bits in macOS Sierra or thesystem will not allow you to connect to servers with it.

Optionally, you can also specify your email address with -C (otherwiseone will be generated off your current macOS account):

The first prompt you will see asks where to save the key. However, there areactually two files that will be generated: the public key and the privatekey.

This prompt refers to the private key and whatever you enter will alsogenerate a second file for the public key that has the same name and .pubappended.

If you already have a key then specify a new filename. I use manySSH keys so I oftne name them 'test-deploy', 'prod-deploy', 'ci-server'along with a unique project name. Naming is one of those hard computerscience problems, so take some time to come up with a system that works foryou!

Next you will see a prompt for an optional passphrase:

Mac Os X Generate Ssh Key Pair

Whether or not you want a passphrase depends on how you will use the key.The system will ask you for the passphrase whenever you use the SSH key,althoughmacOS can store the passphrase in your system Keychainafter the first time you enter it. However, if you are automating deploymentswith a continuous integration server likeJenkins then you will not want a passphrase.

Note that it is impossible to recover a passphrase if it is lost. Keepthat passphrase safe and secure because otherwise a completely new key wouldhave to be generated.

Enter the passphrase (or just press enter to not have a passphrase) twice.You'll see some output like the following:

Your SSH key is ready to use!

What now?
