autoupdate-server
The autoupdate-server package provides a server that allows Lantern clients to compare their running software version against releases posted at Github, if a new version is available, the autoupdate-server will provide a binary diff that the client can use to patch itself.
## Features
- Uses Github releases.
- Generates binary diffs.
Requisites
Make sure you have the bsdiff program installed:
apt-get instal -y bsdiff
yum install -y bsdiff
brew install bsdiff
The bsdiff program is used to calculate a binary diff of two files and
generate a patch.
In order to sign binary files you'll need a keypair:
openssl genrsa -out private.pem 2048
openssl rsa -in private.pem -out public.pem -pubout
The private key must match the public key set in the autoupdate package configuration.
## How to run the autoupdate server
./autoupdate-server -k private.pem
Just testing?
Sure! Use this private key:

-----END RSA PRIVATE KEY-----
Save it to private.pem and run the server pointing to the autoupdate-server
repo that belongs to the getlantern organization:
go run *.go -k private.pem -o getlantern -n autoupdate-server
# 2015/03/13 18:22:41 Starting release manager.
# 2015/03/13 18:22:41 Updating assets...
The private key above matches the public key the https://github.com/getlantern/autoupdate/tree/master/_test_app example uses.
The first time you run the server, it will download all required assets, so you'll probably need to wait a bit before the HTTP server is started.
Once you see the "Starting HTTP server" message you can continue testing a running app.
# 2015/03/13 18:22:43 Starting up HTTP server at :9197.
