Generate a new key pair in a terminal with the next command ssh-keygen -t rsa. The key generator will ask for location and file name to which the key is saved to. Enter a new name or use the default by pressing enter. (Optional) Create a passphrase for the key. YouTube requires you to connect to your YouTube dropbox using a Secure Shell (SSH) connection. SSH is a network protocol that ensures secure data transfer. SSH authenticates you using public-key cryptography. You create a pair of keys: a private key that resides on your client computer and a public key that your dropbox server uses. 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.

Hi there! This post will be pretty straightforward and will cover Windows, Mac, and Linux, so if you don’t know how to do it already, read on.

Windows

Just follow these 5 steps:

Go to this address, and download Git for Windows, after the download install it with default settings
Open Git Bash that you just installed (Start->All Programs->Git->Git Bash)
Type in the following: ssh-keygen -t rsa (when prompted, enter password, key name can stay the same)
Open file your_home_directory/.ssh/id_rsa.pub with your favorite text editor, and copy contents to your Git repository’s keys field (GitHub, beanstalk, or any other repository provider), under your account.
Be sure that you don’t copy any whitespace while copying public key’s content (id_rsa.pub)

Note: your_home_directory is either C:Usersyour_username (on Windows Vista / 7 / 8 / 10), or C:Documents and Settingsyour_username (on Windows XP)

Mac

Follow these 5 steps:

Start the terminal
Navigate to your home directory by typing: cd ~/
Execute the following command: ssh-keygen -t rsa (when prompted, enter password, key name can stay the same)
Open the file you’ve just created ~/.ssh/id_rsa.pub with your favorite text editor, and copy contents to your Git repository’s keys field (GitHub, beanstalk, or any other repository provider), under your account.
Be sure that you don’t copy any whitespace while copying public key’s content (id_rsa.pub)

Linux (Ubuntu)

Follow these 5 steps:

Open console
cd ~
ssh-keygen -t rsa (when prompted, enter password, key name can stay the same)
open file /home/your_username/.ssh/id_rsa.pub with your favorite text editor, and copy contents to your Git repository’s keys field (GitHub, beanstalk, or any other repository provider), under your account.
Be sure that you don’t copy any whitespace while copying public key’s content (id_rsa.pub)

Additional info

When you create private/public SSH keys on your machine (that’s what you did in the above steps), it’s not enough. You need to give your public key to the repository in order to pair the Git server with your local machine (that’d be steps 4. and 5. above).

Most of the popular repositories will give you web interface access to the application, and here’s how it looks like on Github:
After this step, you’re ready to start using Git.

Conclusion

I hope this wasn’t too complicated to follow, and also I hope it was helpful to someone!

While Encrypting a File with a Password from the Command Line using OpenSSLis very useful in its own right, the real power of the OpenSSL library is itsability to support the use of public key cryptograph for encrypting orvalidating data in an unattended manner (where the password is not required toencrypt) is done with public keys.

The Commands to Run

Generate a 2048 bit RSA Key

You can generate a public and private RSA key pair like this:

openssl genrsa -des3 -out private.pem 2048

That generates a 2048-bit RSA key pair, encrypts them with a password you provideand writes them to a file. You need to next extract the public key file. You willuse this, for instance, on your web server to encrypt content so that it canonly be read with the private key.

Export the RSA Public Key to a File

This is a command that is

openssl rsa -in private.pem -outform PEM -pubout -out public.pem

Generate Rsa Key Terminal

The -pubout flag is really important. Be sure to include it.

Next open the public.pem and ensure that it starts with-----BEGIN PUBLIC KEY-----. This is how you know that this file is thepublic key of the pair and not a private key.

To check the file from the command line you can use the less command, like this:

less public.pem

Do Not Run This, it Exports the Private Key

A previous version of the post gave this example in error.

openssl rsa -in private.pem -out private_unencrypted.pem -outform PEM

The error is that the -pubout was dropped from the end of the command.That changes the meaning of the command from that of exporting the public keyto exporting the private key outside of its encrypted wrapper. Inspecting theoutput file, in this case private_unencrypted.pem clearly shows that the keyis a RSA private key as it starts with -----BEGIN RSA PRIVATE KEY-----.

Visually Inspect Your Key Files

It is important to visually inspect you private and public key files to makesure that they are what you expect. OpenSSL will clearly explain the nature ofthe key block with a -----BEGIN RSA PRIVATE KEY----- or -----BEGIN PUBLIC KEY-----.

You can use less to inspect each of your two files in turn:

less private.pem to verify that it starts with a -----BEGIN RSA PRIVATE KEY-----
less public.pem to verify that it starts with a -----BEGIN PUBLIC KEY-----

The next section shows a full example of what each key file should look like.

The Generated Key Files

The generated files are base64-encoded encryption keys in plain text format.If you select a password for your private key, its file will be encrypted withyour password. Be sure to remember this password or the key pair becomes useless.

The private.pem file looks something like this:

The public key, public.pem, file looks like:

Protecting Your Keys

Depending on the nature of the information you will protect, it’s important tokeep the private key backed up and secret. The public key can be distributedanywhere or embedded in your web application scripts, such as in your PHP,Ruby, or other scripts. Again, backup your keys!
