## I GitHub Keys
### I.1
On your VM, go into the ~/.ssh folder. Now generate your SSH keys:
```
ssh-keygen -t rsa -C "your email address"
```
The public key should look like this:
```
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDLrriuNYTyWuC1IW7H6yea3hMV+rm029m2f6IddtlImHrOXjNwYyt4Elkkc7AzOy899C3gpx0kJK45k/CLbPnrHvkLvtQ0AbzWEQpOKxI+tW06PcqJNmTB8ITRLqIFQ++ZanjHWMw2Odew/514y1dQ8dccCOuzeGhL2Lq9dtfhSxx+1cBLcyoSh/lQcs1HpXtpwU8JMxWJl409RQOVn3gOusp/P/0R8mz/RWkmsFsyDRLgQK+xtQxbpbodpnz5lIOPWn5LnT0si7eHmL3WikTyg+QLZ3D3m44NCeNb+bOJbfaQ2ZB+lv8C3OxylxSp2sxzPZMbrZWqGSLPjgDiFIBL w.buchanan@napier.ac.uk

## I What I should have learnt from this lab?
On your Ubuntu instance setup your new keys for ssh:
```
ssh-add ~/.ssh/id_git
```
Now create a Github account and upload your public key to Github (select Settings-> New SSH key or Add SSH key). Create a new repository on your GitHub site, and add a new file to it. Next go to your Ubuntu instance and see if you can clone of a new directory:
git clone ssh://git@github.com/<user>/<repository name>.git
If this doesn’t work, try the https connection that is defined on GitHub.
## J What I should have learnt from this lab?
The key things learnt:
* The basics of the RSA method.
