Examples of PasswordPattern

org.owasp.passfault.PasswordPattern
This class stores information about a password pattern that was identified. In addition it contains specific how the size of the pattern and the part of the password that matched the pattern. Note that some finders have the same cost regardless of the specific pattern finding, but other do not. For example, a dictionary word will have the same cost for all words in the dictionary, but a keyboard sequence will have a higher cost for longer sequences. @author cam
