  -l, --list              List available modules
  -v, --version <value>   Print the version
  --help                  prints java -jar shard-1.2.jar -u username-here -p password-herethis usage text
List available modules:

Available modules:
The master branch has modules for GitHub, BitBucket, and Kijiji as well.

Given a username and password shard will attempt to authenticate with multiple sites:

21:16:25.950 [+] Running in single credential mode
21:16:30.302 [+] username-here:password-here - Reddit, Instagram
To test multiple credentials supply a filename. By default this expects one credential per line in the format "username":"password" . Custom formats can be supplied with the --format option
$ java -jar shard-1.2.jar -f /tmp/creds.txt
21:16:39.501 [+] Running in multi-credential mode
21:16:39.516 [+] Parsed 2 credentials
21:16:42.794 [+] username1:password1 - Reddit, Instagram
21:16:45.189 [+] username2:password2 - Facebook, LinkedIn, Twitter

Grab the latest release from the release tab , which was built as a fat jar using sbt assembly.
Build it yourself using sbt, sbt assembly

Developing a new module
Adding a new module is easy. Create a new class that inherits from AbstractModule in the module package and add the module to the ModuleFactory .
The AbstractModule has one abstract method:
  def tryLogin(creds: Credentials): Boolean
This method takes a Credentials object and returns a boolean indicating a successful login. I recommend using the TwitterModule as an template.
  • JSoup is used for HTTP communication and HTML parsing
  • spray-json is used for handling json
