[Ruby] Passgen [Updated]

Inori · 03-26-2015, 01:55 AM

I decided to make a random password generator because narwhals and the unicorn on Canadian parliament (I shit you not, it exists (Pic)).

It outputs itself to password list.txt in an array format, mainly because I don't know how to get it to do anything else but it could be useful for use in another program on import.

Anyway, enjoy!

Code:

norm = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]
caps = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]
nums = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
puts "How many passwords would you like to generate?"
num = gets.to_i
system "cls"
puts "Password length:"
len = gets.to_i
system "cls"
puts """
Which characters would you like to use?
[1] a-z, 0-9
[2] A-Z, 0-9
[3] a-z, A-Z, 0-9
"""
type = gets.chomp
system "cls"
case type
	when "1"
	    arr = [norm,nums].flatten
	when "2"
	    arr = [caps,nums].flatten
	when "3"
	    arr = [norm,caps,nums].flatten
	else
    	exit
end
passwd_set = []
output = File.open("password list.txt", "w")
passwd_set << arr.sample(len).join
output << passwd_set

Update:
More efficient
