Password strength checker for Firefox Accounts

• Maintains a bloom filter with list of common/leaked passwords
• Checks for the presence of common passwords

Usage:

• Create a new instance of the password checker, like so: var checkpassword = new PasswordCheck(options); where options can be:

  options: {
    minLength : integer, // minimum length of password, default 8
    noOfHashFunctions: integer // no of hash functions to use for the bloom filter, default 8
    // do not change noOfHashFunctions unless you also change it in the bloomfilter file.
  }
  

• Call the checkpassword with a callback, like so:

  checkpassword(password, callback);
