  -p, --password <value>  Password to test
  -f, --file <value>      File containing a set of credentials
  --format <value>        The format of the credentials. Must be a regular expression with 2 capture groups. The first capture group for the username and the second capture group for the password. Defaults to a regex that will match:
	"username":"password"
  -l, --list              List available modules
  -v, --version <value>   Print the version
  --help                  prints this usage text

List available modules:

$ java -jar shard-1.2.jar -l
Available modules:
        Facebook
        LinkedIn
        Reddit
        Twitter
        Instagram

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

$ java -jar shard-1.2.jar -u username-here -p password-here
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

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.

Dependencies:

• JSoup is used for HTTP communication and HTML parsing
• spray-json is used for handling json
