### Step 2: – Download Your EC2 Key Pair File

This Key pair file that you downloaded in [AWS ubuntu setup || launch an AWS EC2 Server](https://technotaught.com/aws-ubuntu-setup-launch-an-aws-ec2-server/)
i.e .pem file. Now we require here.

A key pair consists of a public key that AWS stores and a private key file that 
you store (downloaded as PEM file). PEM stands for Privacy Enhanced Mail and is 
a widely used X.509 encoding format used for security certificates. Together, the
two keys enable you to securely connect to your EC2 instance using SSH.

downloaded.

Then click on Open and it should connect you to your publically accessible EC2 instance(
in this scenario, this instance would be referred to as the Bastion host or a jump
box).

#### In PuTTY security alert click Yes to add instance host as trustable. 

If this is the first time you have connected to this instance, PuTTY displays a 
security alert dialog box that asks whether you trust the host to which you are 
connecting.
