Examples
Probably the format is not that easy to understand but it is the most flexible I could think of. Here some example for the format string:"0:0:0:0:0:0" = 6 digit random number
"a:a:a:a:a:a:a:a" = 8 digit random string
"A:a:a:a:a:a" = String starting with capital letter and five lower letters afterwards
"1:1:1:1:1:1:1:1" = 8 digit binary number
"f:f:f:f:f:f" = 6 digit hex number with lower letters
"C:e:c:e:c:e:" = 6 character "good" sounding random word
"aA0):aA0):aA0):aA0):aA0):aA0):aA0):aA0)" = 8 digit password with everything
"F:F:F:F:F:F:F:F:F:F" = 10 digit hex number with capital letters
