Tricks to add encrypted private SSH key to .travis.yml file

Setup for an easy to use, simple reverse http tunnels with nginx and ssh. It's that simple there's no authentication at all. The end result, a single ssh command invocation gives you a public url for your web app hosted on your laptop.

What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.

Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).

Intercept and manipulate HTTPs traffic with Python and mitmproxy

Intercepts HTTPs Traffic with Python & mitmproxy

Warning

This Gist is created in 2014, and it's highliy outdated now, according to one of mitmproxy's manjor contributor (check his comment below). Thanks for letting us know, @mhils!

Introduction

Modern applications usually make use of back-end API servers to provide their services. With a non-transparent HTTPs proxy, which intercepts the communication between clients and servers (aka the man-in-the-middle scheme), you can easily manipulate both API requests and responses.

If you want to give only Travis-CI access to a private key or secret file in your repository, you will need to encrypt it, but rather than storing the entire encrypted file in an environment variable, just store the a secret password in a secure environment variable that you will use to encrypt and decrypt your private key file. The encryption o…
# generate your private key, put the public key on the server you will be connecting to
ssh-keygen -t rsa -f ./my_key
# generate the password/secret you will store encrypted in the .travis.yml and use to encrypt your private key
cat /dev/urandom | head -c 10000 | openssl sha1 > ./secret
# encrypt your private key using your secret password
openssl aes-256-cbc -pass "file:./secret" -in ./my_key -out ./my_key.enc -a
# download your Travis-CI public key via the API. eg: https://api.travis-ci.org/repos/travis-ci/travis-ci/key

Steps to install a Comodo PositiveSSL certificate with Nginx.

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert
