Methods

Modifier and Type	Method and Description
static java.lang.String	generateSequence(java.lang.String salt, java.lang.String password, PasswordInputMethod input) Generates a hashed sequence using the given password. If input type is VIRTUAL_KEYBOARD this method splits password into subsequences and applies hash+salt to each subsequence. Returns a string with generated subsequences joined by a separator. SPLIT_PASSWORD_LENGTH constant is used to define each subsequence length. SPLIT_PASSWORD_SEPARATOR constant is used as separator to join subsequences.
static boolean	isValid(java.lang.String value, Password password) Determines whether the given plain value is equals to the given password. This method will process (hash+salt) the given value and will try by brute force* to match the given password. * Only if the value can be split in sequences
