title: unable to ssh to AWS codecommit repository, public key contents change
body: <p>Below public key (modified) when I upload to IAM changes to a different format:</p>
  
  <pre><code>ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDZeqQA7Uc+dsdfasWqqqqqqqqqqqqqq6hvmFLZHfoVsebiGkW5t0g6wCaaaaaaaaaaaaaauD0rsW/IoWsYC95Ax5Kdo5N1yGkIs2m1l6DP0JCx1FuZN6DPp4HcccccVmfA3s88BTC84890qdfffffffffffffffff1/0HSqJyBTGrplZcFSesX7cVUGRdiOEF1iBW743 xxxxx@xxxx-VirtualBox
  </code></pre>
  
  <p>changes to following format (modified) when I view the popup by clicking show SSH key:</p>
  
  <pre><code>-----BEGIN PUBLIC KEY-----

  -----END PUBLIC KEY-----
  </code></pre>
  
  <p>Is this the reason I always get following error:</p>
  
  <pre><code>ssh git-codecommit.eu-west-1.amazonaws.com
  sign_and_send_pubkey: signing failed: agent refused operation
  Permission denied (publickey).
  </code></pre>
  
  <p>My config file (modified) is:
  cat .ssh/config </p>
  
  <pre><code>Host git-codecommit.eu-central-1.amazonaws.com
  User APsssssssDDDDDDDwwwAQ
  IdentityFile ~/.ssh/id_rsa
  </code></pre>
  
  <p>I cannot understand what is going wrong. I used the instructions in
