Method Detail

execute

public java.util.List<Match> execute(java.lang.CharSequence password)

Identifies sequence by looking for repeated differences in unicode codepoint. this allows skipping, such as 9753, and also matches some extended unicode sequences such as Greek and Cyrillic alphabets.

for example, consider the input 'abcdb975zy'

password: a b c d b 9 7 5 z y index: 0 1 2 3 4 5 6 7 8 9 delta: 1 1 1 -2 -41 -2 -2 69 1

expected result: [(i, j, delta), ...] = [(0, 3, 1), (5, 7, -2), (8, 9, 1)]

Parameters:

password - the password to analyze for patterns.

Returns:

a list of matches identifying patterns found within the password.
