Sound reasonable in the same time it will not always obviously which
minMasked to use.
For example already mentioned credit card numbers in fact can have varying
length as I remember up to 24 digits.
As I understood I created this function for specific case which you had.
Can you provide some examples from real life when minMasked was needed?---
