remove travis encryption keys -- generate a new ssh key

sudo gem install travis

cd deploy/
travis login --org
ssh-keygen -t ecdsa -b 256 -C "deploy" -f id_deploy -N ""
cat id_deploy.pub (copy this into deploy@dev.ole.org:.ssh/authorized_keys)

ignacio@home:~/builder/deploy$ travis encrypt-file id_deploy
encrypting id_deploy for treehouses/builder
storing result as id_deploy.enc
DANGER ZONE: Override existing id_deploy.enc? |no| yes
storing secure env variables for decryption

Please add the following to your build script (before_install stage in your .travis.yml, for instance):

    openssl aes-256-cbc -K $encrypted_eae07f48be7a_key -iv $encrypted_eae07f48be7a_iv -in id_deploy.enc -out id_deploy -d

Pro Tip: You can add it automatically by running with --add.

Make sure to add id_deploy.enc to the git repository.
Make sure not to add id_deploy to the git repository.
Commit all changes to your .travis.yml.
ignacio@home:~/builder/deploy$

rm id_deploy

edit .travis.yml

before_deploy:
 - openssl aes-256-cbc -K $encrypted_eae07f48be7a_key -iv $encrypted_eae07f48be7a_iv -in deploy/id_deploy.enc -out deploy/id_deploy -d

git add -u

also, optionally, we can remove the old key from https://travis-ci.org/treehouses/builder/settings
