Mac Generate Ssh Key Rsa

Updated on November 5, 2019

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. Oct 05, 2007  ssh-keygen Tutorial – Generating RSA and DSA keys. Ssh-keygen can generate both RSA and DSA keys. RSA keys have a minimum key length of 768 bits and the default length is 2048. When generating new RSA keys you should use at least 2048 bits of key length unless you really have a good reason for using a shorter and less secure key.

Want to learn how to generate an RSA Key Pair on a Mac® device using JumpCloud®? View the video below for a walkthrough. Please note that this process can be replicated on a Linux® device as well. If you wish to generate a RSA Key Pair on Windows you will need to use the PuttyGen tool.

In this video you will learn how to generate an RSA Key Pair for use with a Single Sign connector, and a secure connection with the service provider.

Why?¶

  • Increased security: they are nearly impossible to brute force or guess
  • Ease of management: Need access to a friend’s computer? Just send them yourpublic key. No more creating and changing random passwords.
  • Type less passwords: You can use ssh-agent to cache your key, so you can usessh without typing your password every time
  • Automated scripts: Because you don’t need to type your password every time,its easier to automate tasks that require ssh

How?¶

Linux/OS X (Short Version)¶

Generate Ssh Key Github

  • Run this command:

  • Accept the default location, and enter a secure passphrase that you (and onlyyou) will remember.

  • Email us the contents of ~/.ssh/id_rsa.pub

Linux/OS X (Detailed)¶

  • Use the ssh-keygen utility to create your key. For a 2048 bit RSA key do:

For increased security you can make an even larger key with the -b option. Forexample, for 4096 bits do:

The OSL recommends using RSA over DSA because DSA keys are required to be only1024 bits.

  • When prompted, you can press Enter to use the default location(/home/your_username/.ssh/id_rsa on Linux, or/Users/your_username/.ssh/id_rsa on Mac) if you don’t already have a keyinstalled, or specify a custom location if you are creating a second key (orjust want to for whatever reason).
  • Enter a passphrase at the prompt. All people connecting to OSL servers mustuse a passphrase. This is just a password used to unlock your key. Ifsomeone else gets a copy of your private key they will be able to log in asyou on any account that uses that key, unless you specify a passphrase. If youspecify a passphrase they would need to know both your private key andyour passphrase to log in as you.
  • After you re-enter your passphrase, ssh-keygen may print a little picturerepresenting your key ((you don’t need to worry about this now, but it ismeant as an easily recognizeable fingerprint of your key, so you could know ifit is changed without your knowledge - but it doesn’t seem to be widely used))then exit.
  • Your private key should now be in the location you specified, and your publickey will be at that same location but with ‘.pub’ tacked onto the filename.

Note

If you are creating this key for use with an OSL SSH account, copy and pastethe public key into your ticket. If we didn’t ask you for a public key but youwant one added to your account email it to support@osuosl.org, being sure tospecify who you are and what project(s) you are associated with.

  • Or, to use the public key on a computer under your control, add it to~/.ssh/authorized_keys (you can specify multiple public keys, one perline).
  • Never share your private key file, only the public key file.

Windows (using putty)¶

  • In the “Key” section choose SSH-2 RSA and press Generate.
  • Move your mouse randomly in the small screen in order to generate the keypairs.
  • Enter a key comment, which will identify the key (useful when you use severalSSH keys).
  • Type in the passphrase and confirm it. The passphrase is used to protect yourkey. You will be asked for it when you connect via SSH.
  • Click “Save private key” to save your private key.
  • Click “Save public key” to save your public key.
