Guesses passwords of increasing lengths, testing codepoints in an ordered manner (typically increasing).
examples:
- "aa" is weaker than "zz"
- "aaa" is stronger than "zz"
- "🔒" is stronger than "aa"
- "🔒" is weaker than "zzzz"
Same as above, but the attacker assumes the password has a given length.
examples:
- "0" is infinitely strong, if assumed size isn't 1.
- "a" repeated n times, grows in strength exponentially, if assumed size matches n.
- "aaa" is weaker in this model when compared to the previous one (if assumed size 3), as smaller passwords will never be checked.
