38 | 


--------------------------------------------------------------------------------
/RubyCrackMaster.rb:
--------------------------------------------------------------------------------
 1 | # RubyCrackMaster.rb
 2 | 
 3 | # Function to obfuscate characters
 4 | def obfuscate(char)
 5 |   (char.ord ^ 0x5A).chr
 6 | end
 7 | 
 8 | # Function to get the obfuscated correct password
 9 | def get_obfuscated_password
10 |   password = "SecurePass123"
11 |   password.chars.map { |c| obfuscate(c) }.join
12 | end
13 | 
14 | # Function to check the password
15 | def check_password(input)
16 |   obfuscated_password = get_obfuscated_password
17 |   obfuscated_input = input.chars.map { |c| obfuscate(c) }.join
18 |   obfuscated_input == obfuscated_password
19 | end
20 | 
21 | puts "Welcome to RubyCrackMaster!"
22 | print "Please enter the activation password: "
23 | input = gets.chomp
24 | 
25 | # Small delay to complicate analysis
26 | sleep(0.5)
27 | 
28 | if check_password(input)
29 |   puts "Congratulations! You have cracked RubyCrackMaster."
30 | else
31 |   puts "Incorrect password. Please try again."
32 | end
33 |
