Yesterday I got my hands on my very first Lincoln (five dollars) bill, they seem much more older and used than Euro banknotes. As I had already made a Euro note serial number validation algorithm in PHP I thought: “why don’t I do the same for dollar bills?”.
Well you may already know the Murphy Law “If anything can go wrong, it will”, well believe me: it’s true.
Have you ever come across a fake Euro banknote? Well, most of us probably have (at least those of us who live in the European Union, like me) - more than 300 thousand Euro banknotes are falsified every year.
Today I’ll be sharing an algorithm that I use quite a lot, for generating passwords that are easily memorable and spelled - one may also call this type of passwords mnemonic passwords.
