If you are like me, who forgets important passwords for credit nd debit cards, and then having to phone banks to send another password, I developed a simple technique that is fairly safe to scramble your password using a simple techniqe and writing this down instead of the actual password.
This simple techniqe uses a few digits that you can remember, and apply it throughout to all your credit and debit cards including online banking pins.
You only need to remember this unique number which you must never give anyone clue about. This number can be minimum 2 digits or more, but for most purposes a 2 digits will more than suffice.
However, if you were going to forget your pin number whilst going shopping then you must carry your scrambled number with you, which you can write down, so even if someone saw your scrambled number, it won't be any good to anyone, as it is not a real 4 digit pin number.
The technique uses a simple maths principle, the two digits must not be same numbers like 11, 22, 33, 44, and so on but must be two different numbers like 12, 21, 45, 37 and so on. Edit: Also avoid numbers with zeros like 10,20,30, 40 and so on, including single numbers like 01,02, 03, but you can have as many digits as you want, two should be minimum, 3 is good, 4 is ideal but can take longer to encrypt and decrypt,
Let us assume your actual password that you don't want to lose so you scramble it first and then write it down in your diary or save it in your computer, but the two digits number you must never tell anyone or write it down. For extra security you can even use 3 digits or 4 digits to scramble, the more you scramble the less anyone can descramble.
Let us assume your password or pin number is 2345, and your two digits scrambling number is 25,
Step 1.
take 2 first from your scrambling number
write down 2222 and subtarct 2345, do not use a calculator for this and do not use or pass any carry out or borrow, from adjacnet digits,
You treat each digit individually, hence no carry or borrow from adjacent digits,
so strating either from right to left or left to right, does not matter, the result will be the same as we are not borrowing or carrying out overflow.
so start from right, take 2, minus 5 from it, but since you can't as 2 is smaller than 5, so we make 2 as if it is 12, we pretend we have borrowed 10 from somewhere, but not from any of the other digits.
so this gives us 12-5= 7
similarly we take the next digit which is 4, (since our actual pin number is 2345)
so taking the next digit 4 and subtracting it from 2, we can't so we add 10 again from somewhere, hence we minus 4 from 12, gives us 8
third digit of our pin is 3, so we di the same again, we subtract 3 from 2 but we make 2 look like it is 12 by borrowing 10 from somewhere, the rsult is 9
finally our last digit of our pin (since we were dealing from right to left) is 2, and we can now take away 2 from 2 and we need not borrow 10 from anywhere, so the answer is 0
hence after first scramble our answer is 0987
2 2 2 2 (first digit of your secret scranmbling code)
2 3 4 5 (Your actual pin number you subtract from above)
--------
0 9 8 7 (this is your intermediate scrambled number)
Now take the 2nd digit of your secret 2 digit scrambling number which in our case is 5 (remember our secret scrambling code was 25)
Now we do the same again to 0987 but this time we are subtracting it from 5555, hence we get the following:-
5 5 5 5
0 9 8 7
--------
5 6 7 8
so by scrambling our original Pin number which was 2345, we get a scrambled number 5678, we can now write this down safely since it won't be any good to anyone, but if we forget our actual Pin number we can use the above scrambled number to get to our original number, here is what you now have to do.
Do the same as you did above i.e. Subtracting but this time instead of using 2 first we use 5 first and then 2, but we just do another subtraction, and not addition.
example:
we first take 5s
5 5 5 5
5 6 7 8
--------
0 9 8 7 (our intermediate number)
now we take 2s
2 2 2 2
0 9 8 7
---------
2 3 4 5 this is our original Pin number.
The two digits you must remember as your descrambling code number can be any number, year you rememer the most, someone you love their birthdate, or year, or just any favourite number that you are unlikely to not remember.
Distinctively possible, but If upon scrambling your number comes almost same as your original Pin number then you must choose another number.
AND REMEMBER NOT TO USE A CALCULATOR to subtract as the calculator will borrow and carry out overflows and underflows.
All you need to remember is we are not actually borrowing or carrying out 10s, we pretend we get this when we need to from our invisible black energy in our univeres!
