In response to Losschabossdragon, "the security of alphanumeric and lower and upper cases" think of it this way; if all passwords were 8 characters and you use numbers only my home pc could crack that in milliseconds (there's a maximum of 10 possibilities per character 0-9) with a total possible 1,073,741,824 combinations. Now add lower case letters = 36 possibilities (0-9 + a-z). Add upper case = 62 possibilities. Add 10 unique characters = 72. That does not mean it will take 7.2 times longer to crack. That's just one character! It has to guess the correct combination of characters. The possible combinations =1.0531229166855719e+65 (e65 means x10 with an exponent of 65) or 10,531,229,166,855,719,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 A lottery ticket has far fewer possible combinations.
