How to Make an SSH Key.md

Introduction

This page lists the steps needed to create an ssh key for Biola System Administration use. We currently use ecdsa with 521 bits.

Step 1: Create an SSH Key

  1. Run the following in terminal:
    • Linux 
      ssh-keygen -t ecdsa -b 521 -f ~/.ssh/desiredSSHKeyFilename
    • Windows 
      ssh-keygen -t ecdsa -b 521 -f $HOME/.ssh/desiredSSHKeyFilename
  2. Enter your desired passphrase and press enter.
  3. Enter your desired passphrase again and press enter.

Step 2: Set the SSH Directory and File Permissions

  • Linux 
    sudo chown 700 ~/.ssh; sudo chown 600 ~/.ssh/*
  • Windows 
    icacls $HOME\.ssh /inheritance:r /grant:r "`"$($env:USERNAME)`":(OI)(CI)F" /T ; icacls $HOME\.ssh\* /inheritance:r /grant:r "`"$($env:USERNAME)`":(OI)(CI)F" /T
