The following ratio calculations are based on testing SequenceMatcher like this: for i in range(0,6): print(10**i, SequenceMatcher(a='A', b='A'*(10**i)).quick_ratio()) which yields: 1 1.0 10 0.18181818181818182 100 0.019801980198019802 1000 0.001998001998001998 10000 0.00019998000199980003 100000 1.999980000199998e-05 This means a length_ratio of 10 should never yield a similarity higher than 0.2, for 100 this is down to 0.02 and for 1000 it is 0.002. This can be calculated via 2 / length_ratio. As a result we avoid the potentially expensive sequence matching.  )r9)rmax_similarityvalueZpwd_lenZlength_bound_similarityZ value_lenrrrexceeds_maximum_length_ratios rDc@s4eZdZdZdZedfddZd ddZd d ZdS) UserAttributeSimilarityValidatora Validate that the password is sufficiently different from the user's attributes.
