First cool thing that everybody knows already: Mac OSX is based on Unix so you get ssh out of the box.

1. Mac Os X Generate Ssh Key Password
2. Generate Ssh Key Git Mac Os X
3. Mac Os X Add Ssh Key
4. Generate Ssh Key Osx

Adding your SSH key to the ssh-agent. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source. Second cool thing you may not know: OS X 10.5 actually also comes with an ssh key agent (ssh-agent). That means that, without any additional software (like PuTTY Agent on Windows.), Mac OSX can actually load an encrypted private key into memory and remember it for all subsequent connections.

It is developed to handle all aspects of building a home. Key generator chief architect x8 library.

Third cool thing that almost seems too good to be true: ssh-agent can store the passwords of the encrypted keys into your keychain. Than means that you have to tell it once to remember the decryption password for your key(s) like this:

ssh-add -K .ssh/id_whatever_your_rivate_key_is

And next time you log into your mac and try to ssh somewhere, your private key will be loaded automagically (as long as your keychain is unlocked of course).

Very groovy!!

Mac Os X Generate Ssh Key Password

How do I generate ssh keys under Linux / UNIX / Mac OS X and *BSD operating systems for remote login?
SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if required. You can create ssh keys as follows on any Linux or UNIX-like operating systems including Mac OS X.[donotprint][/donotprint]

ssh-keygen command to Generate SSH Keys

Generate Ssh Key Git Mac Os X

The ssh-keygen command generates, manages and converts authentication keys for ssh client and server usage. Type the following command to generate ssh keys (open terminal and type the command):
$ ssh-keygen
Generate SSH keys looks as follows:

The above command creates ~/.ssh/ directory. So if your user name is vivek, than all files are stored in /home/vivek/.ssh/ or $HOME/.ssh/ directory as follows:

• $HOME/.ssh/id_rsa – Your private key. Do not share this file with anyone. Keep it private
• $HOME/.ssh/id_rsa.pub– Your public key.

Please note that the passphrase must be different from your current password and do not share keys or passphrase with anyone. Also, make sure you have correct and secure permissions on $HOME/.ssh/ directory:

SSH Keys Are Generated, What Next?

You need to copy $HOME/.ssh/id_rsa.pub file to remote server so that you can login using keys instead of the password. Use any one of the following command to copy key to remote server called vpn22.nixcraft.net.in for vivek user:
ssh-copy-id vivek@vpn22.nixcraft.net.in
On some *nix system such as OS X ssh-copy-id command may not be installed, use the following commands (when prompted provide the password for remote user account called vivek) to install/append the public key on remote host:
ssh vivek@vpn22.nixcraft.net.in 'umask 077; mkdir .ssh'
cat $HOME/.ssh/id_rsa.pub ssh vivek@vpn22.nixcraft.net.in 'cat >> .ssh/authorized_keys'
To login simply type:
ssh vivek@vpn22.nixcraft.net.in
The following command will help to remember passphrase
exec ssh-agent $SHELL
ssh-add
ssh vivek@vpn22.nixcraft.net.in

Optional ssh-keygen command syntax for advance users

The following syntax specifies the 4096 of bits in the RSA key to creation (default 2048):
ssh-keygen -t rsa -b 4096 -f ~/.ssh/aws.key -C 'My AWs cloud key'
Where,

• -t rsa : Specifies the type of key to create. The possible values are “rsa1” for protocol version 1 and “dsa”, “ecdsa”, “ed25519”, or “rsa” for protocol version 2.
• -b 4096 : Specifies the number of bits in the key to create.
• -f ~/.ssh/aws.key : Specifies the filename of the key file.
• -C 'My AWs cloud key' : Set a new comment.

Now install the ~/.ssh/aws.key, run:
ssh-copy-id -i ~/.ssh/aws.key user@aws-server-ip
Test it with the ssh command:
ssh -i ~/.ssh/aws.key ec2-user@aws-server-ip
