I do not understand what they mean by 'modify your /.ssh/config file ' & the Host. AddKeysToAgent yes UseKeychain yes IdentityFile /.ssh/idrsa. Ssh-add -K /.ssh/idrsa does not work on terminal either, as the results says 'no such file or directory' I saved the key file to my Desktop folder when ssh-keygen prompted me for a location. You can add as many keys as you like and ssh-add -l will show you which keys are registered. When you reboot, you’ll notice that ssh-add -l is empty which is different from how it works on macOS 10.11 and earlier which automatically re-added the keys it knew about. In Sierra, Apple has changed it so that you now need to explicitly add the. MacOS Sierra doesn’t seem to remember SSH keys between reboots. Type in ssh-add -l and you should see one lone SSH key. I updated to Mac OS X Sierra (10.12.6.
This guide goes through setting up SSH keys on macOS Mojave 10.14 back to Mac OSX 10.11 and also a secure password-less SSH connection between a local macOS workstation and a remote server also running a Linux variant operating system.
The process requires generating a public and private key on the local computer and then adding the public key to the remote servers authorised list. What is great about this is that it allows a password prompt free session, handy for a lot of uses.
First thing that you need to do on your macOS machine is to create a directory that will store your SSH keys. Then you will generate a public and private key for your account, launch the Terminal and punch in some commands:
Create a .ssh Directory
Change to the home directory
Create a SSH directory name .ssh and move into it
Make sure that the file permissions are set to read/write/execute only for the user
Create your private and public key, the blank quotes at the end of the command gives the private key no password, so allowing for passwordless logins!
Change into the .ssh directory and list the contents of that .ssh directory
Thats your SSH keys created, the private key is the id_rsa and the public one is the id_rsa.pub, don’t give out the private one always keep that one only on your local machine.
Sharing the Public Key
Create an authorized_keys in the .ssh directory of the remote computer that you want to connect to.
You can create automatic logins by adding the contents of your public key to the authorized_keys file on the remote device.
To see and copy your public key use the cat command and copy the contents:
On the remote computer if needed, change the permssions on the authorized_keys file to write to add the public key, on a new line paste in your public key, and change permissions back to read only after for security.
Allow write on authorised_keys
Paste the entire id_rsa.pub content with vi or nano into the authorized_keys file, if using nano use the -w flag to not use incorrect line breaks.
If the remote host does not have an “authorized_keys” file simply create one and after the public key is pasted in don’t forget to takeaway write permissions.
Going Both Ways
So now when you connect via SSH no password is prompted as the remote computer has your public key which is only decrypted by your private key held in your local .ssh/ directory. If you want the communications to be bilateral then repeat the process in the opposite order between the two.
Now the two computers can securely connect with no password prompting, making it ideal to script between the two for file copies or back ups.

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.

Choosing a key modulus greater than 512 may take a few minutes. Use the generateKey method of the SubtleCrypto interface to generate a new key (for symmetric algorithms) or key pair (for public-key algorithms). Const result = crypto.subtle.generateKey(algorithm, extractable, keyUsages). Click on the “Generate private and public key” button in the plugins settings. If the key generation was successful, dismiss the alert message and download the public-key.pem file, by clicking on the “Download private and public key” link. Save the plugin settings.
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.
Mac Get Ssh Key
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:
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.
Mac Os Sierra Generate Ssh Key Github
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?
Now that you have your public and private keys, I recommend building anddeploying some Python web apps such as:
