How-To Generate your SSH key

Open the Terminal and execute the command below using your corporate e-mail:ssh-keygen -t rsa -b 4096 -C "your_email@company.com"

At the interpreter’s suggestion to enter the path to the file, just press Enter:
Enter file in which to save the key

You can optionally set a password or just press Enter 2 times:
Enter passphrase (empty for no passphrase)
Enter same passphrase again:

When done, the key generation program will notify you of its location:
Your identification has been saved in /Users/username/.ssh/id_rsa
Your public key has been saved in id_/Users/username/.ssh/id_rsa.pub

Now you need to display the contents of the public key. The file has the extension pub. You can do this using the cat command:
cat /Users/username/.ssh/id_rsa.pub

The contents of the file will be output to the terminal:

ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAklOUpkDHrfHY17SbrmTIpNLTGK9Tjom/BWDSU
