To configure your GitHub Enterprise account to use your new (or existing) SSH key, you'll also need to add it to your GitHub Enterprise account.
Before adding a new SSH key to your GitHub Enterprise account, you should have:
After adding a new SSH key to your GitHub Enterprise account, you can reconfigure any local repositories to use SSH. For more information, see 'Switching remote URLs from HTTPS to SSH.'
Note: DSA keys were deprecated in OpenSSH 7.0. If your operating system uses OpenSSH, you'll need to use an alternate type of key when setting up SSH, such as an RSA key. For instance, if your operating system is MacOS Sierra, you can set up SSH using an RSA key.

This is a brief guide to creating a public/private key pair that can be used for OpenSSL.While the 'easy' version will work, I find it convenient to generate a single PEM bundleand then export the private/public key from that as needed. This document also covers howto add and remove a password from your private key and how to make sure that keychainwill automatically unlock it when you sign in.
Generate an ssh key-pair:
/blur-game-license-key-generator.html. If you just pound enter through the setup procedure then you will end up with a new keypair created in the default location: /Users/yourname/.ssh/
. There will be two files:
id_rsa
This is your private key, you must keep it secret and never allow anybodyelse to gain control of it. Treat this key like a password, keep it safe and makea backup copy. You can add it to keychain using ssh-add -K ~/.ssh/id_rsa
.
id_rsa.pub
This is your public key, you can share it freely. This part of the keyis used during authentication to encode a message which can only be decoded with theprivate key. It cannot be used to derive the private key so there is no risk insharing it.
When a server administrator asks for a copy of your public key, send them a copy of theid_rsa.pub
file. They'll be able to add it to your user account's list of authorizedkeys and that will enable you to log in without typing a password.
This method involves creating the keys as a bundle, exporting the public key andmanually setting the permssions on all of the paths. You'll also have to configureOpenSSH to use your new bundle for authentication.
A summary of the steps follows:
I prefer to generate a certificate using OpenSSL directly, then export the private orpublic-key in the necessary format as needed. The benefits to this appraoch are three-fold:
In order to generate the key I prefer to use OpenSSL directly rather than the ssh-keygen tool.While it is possible to provide flags to ssh-keygen
using OpenSSL gives us access to optionsthat are not avaiable in the standard Mac OS X version of SSH but doesn't require us to buildthe SSH client from scratch.
Unfortunately the version of OpenSSL that ships with Mac OS x is rather dated and so it'smissing some of the features of the latest versions. One of those features is the genpkey
command which is the new recommended way to generate keys. Assuming you have Homebrewinstalled (see: https://brew.sh) you can install an up-to-date version of OpenSSL with:
Many packages that you install with homebrew are likely to depend on OpenSSL anyway so thisis not a terrible idea even if you don't care about using OpenSSL directly.
If you're interested in rebuilding openssh you should link against LibreSSL sothat passwords can be installed in your keychain.
This is a relatively new option and caution should be taken because compatibilitymay not be perfect. LibreSSL is not intended to be a 1:1 replacement for OpenSSL.
It appears that just building OpenSSH will not have it request key information fromthe Mac OS X keychain, nor will it automatically start SSH-Agent so there may besome trouble-shooting steps required if you prefer to go this path. I do not builda new version of SSH.
OpenSSH requires that keys be stored in ~/.ssh
and that path must be restrictedso that only the user can access it. It also requires that any identify files beaccessible only by the user too. Permssions for ~/.ssh/config
can be more relaxedbut it is good practice to keep those private so as not to leak inforamtion aboutuser names or servers you connect to.
Create the directories by running:
While this will create the directory you will have to modify the default permissions.Read/write/execute for the owner and no access for any other user is required. Recall,the execute flag on a directory allows you to view its content.
You might want to create an empty ssh config file and set appropriatepermissions so that you don't have to remember how to do it later whenthere's some problem and you are half-asleep, drunk, and responding to aPagerDuty alert.
You can save a few copy steps if you're following this guide by changinginto your ssh path for the remaining steps:
The first step to generating keys is to create the bundle using OpenSSL. Thisapproach allows us to specify a few extra options when creating keys that arenormally hidden by ssh-keygen
:
The options: are
genpkey
is the new command for generating keys, it supercedes the oldgenrsa
method. Mac OS X's default OpenSSL does not have this command sobuilding your own version is required.
-algorith rsa
uses the RSA algorithm for the key and is recommended formaximum compatibility. Other options include ECDSA
, which is lesscomputationally intensive on very low-end hardware (e.g. 50 MHz ARM) andDH
which has characteristics similar to RSA but is rarely used.
-aes-256-cbc
is the cypher used to encrypt the bundle and causes the userto be prompted for a password. There are a number of available ciphers butAES-256-cbc is among the stronger options available and widely used too.
-outform PEM
there are several output formats that you can use but PEM iswidely used by open source software and tends to be the best supported. Theformat is also nicely encoded so that you can debug with any text editor andhas the advantage of bundling the public and private key into a single filewhich makes them easier to move around. You can always output the public orprivate key from a PEM bundle that contains both.
-pkey_opt …
can be specified multiple times and supplies options to thegeneration function. This can be specified multiple times to suplly severaloptions
rsa_keygen_bits:4096
sets the length of the keys produced. 1024 bits isgenerally considered the absolute minimum for secure communication todaythough there is some concern that they will be broken for well-fundedattackers in the near future so 2048 bits is recommended where possible.Longer keys provide greater security however there is diminishing returnsas key length increases. Also, increasing the key length also increasescomputational costs exponentially (by the cube of the change, so 2048 is8x more demanding than 1024-bit). You may want to use smaller keys forslower hardware or if you find yourself frequently reconnecting due to badconnections during a session for better performance.-out yourname.pem
defines the output file for your bundle. You should storea copy of this certificate in ~/.ssh
so that it can be used to authenticatessh sessions. The file must not be accessible to other users on the system soset the permissions accordingly. You should also store the file and thepassword somewhere safe (like in your password vault or on a USB drive in asafe deposit box).
When generating the key you will be prompted for a password. Make sure to use a verystrong, unique, random password for this file. You won't have to type it in regularlyso generate it with your password vault. In a pinch you can generate a random passwordusing OpenSSL via: openssl rand -base64 48
.
When the bundle has been generated, copy it to your~/.ssh
folder and change itspermissions accordingly:
I prefer to make the bundle read-only for my user so I never accidentally edit it orstrip the password. chmod 0600 ~/.ssh/yourname.pem
would also work if you don't mindit being editable by your user.
You'll want to be able to send the public key to other people and leave it on othercomputers without risking your private key. The easiest way to export your publickey is using the ssh-keygen method which prints it to standard out.
You can always redirect that to a file if you want to send it via email or copy itvia SFTP. Generally I prefer not to keep a copy of my public keys on disk so that I amjustified in always treating ~/.ssh
as a secret.
Remember to either edit your ~/.ssh/config
to specify this bundle as the defaultidentify file by adding the line:
Alternatively you can specify it on a host-by-host basis by using ssh command-lineoptions: ssh -i ~/.ssh/yourname.pem example.com -l someuser
. When you areprompted for a password, remember that you should enter the one used when creatingthe bundle, not the log-in password for your computer or the remote system you areconnecting to.
Finally, you should consider adding the key to your Mac OX X keychain using:
This will store the password in the login Keychain which is unlocked automaticallywhenever you sign in. Storing your password this way means you won't have to re-typethe password you used when creating the bundle in order to use it.
Using ssh -i ~/.ssh/yourname.pem foo.example.com
will also add your key to Keychain.
It's a good idea to add your public key to github.com so that you can pull from privaterepositories and push changes to your public repositories. You can do this at:
Once you've uploaded your public key, other users can download it by going to
For example, my public key is located here: https://github.com/colinstein.keys
You may want to create different key-pairs for different repositories or organizationsand then use ~/.ssh/config
and local .gitconfig
files ot manage those relationships.
After generating keys in the above manner for each github account you can configuressh by editing ~/.ssh/config
and adding entries like the following for each account:
When cloing a repository you would then clone from the appropriate host:
You can also edit the existing git remote by editing the .gitconfig
insidethe checked out repository:
Git also provides a number of ways to configure SSH via git config
andgit remote add foo git@github.com-foo:somegithubuser/somerepo.git
. A fullrun through of those options is well outside the scope of this gist.
