So what are the odds of someone guessing a password up to fifteen characters? Assuming the keyboard is using 66 characters then the odds are 1 out of (66^15) or 1 out of 1.96479337E+27. The (E+27) means move the decimal point 27 places to the right.
The decimal point after the "1" has eight numbers behind it. Move the decimal point 8 places to the right, drop the decimal point then add 27 zeroes behind it. .I have no idea what that combination is called but I am just going to say it's off the charts.
Below is a listing of my commodore 64 password program. It will even work for the VIC-20 and notice on the numbers in line 120 I use also a hypen and an understore. To get small letters or capital letters simply use your commode symbol key plus shift key.
Pay attention to colons, semi-colons and strings. S$ is pronounce S string. To save the program to floppy type SAVE "PASSWORD",8 then press return.
To load the program type LOAD "PASSWORD",8
I write my passwords down on index cards and I make sure I have more than one hidden copy.
If you want to generate passwords with fewer characters simply change the FOR-NEXT statement in line 121: I wouldn't go less than 8. To exucute the program type RUN then press the RETURN
KEY.
121 FOR X =1 TO 15 creates a fifthteen character password.
121 FOR X = 1 TO 8 creates an eight character password.
To created a another password simply press any key or space bar.
