Challenge: Give me feedback about this algorithm/program, your opinion about it, hints how to make it better, more secure etc.
Note: This IS challenge because program has password, so you cannot use program if u dont break it


If someone realy cant break it, ask me, ill give it to you.
I'm now learning Ruby, so im planning to make better version with similar algorithm in Ruby for practical use.
Thanks in advance!
Among programming, im learning english language too, so hope you understand me.
