Mutant Encryption Algorithm

Today's project is more about the same topic of encrypting passwords.This piece of code is aimed to encrypt passwords, but this time it won't return a single character array, but a constantly-changing matrix which contains the password. I am currently working on the decrypting algorithm, which I'm done so far with. As you may deduce from the code, what I do is 'insert' the password character by character into the matrix following this order:

• First element will go in row 0 and a random column between 13 and 36
• Second element will go in row 1 and a random column between 13 and 36

                                                                  .

                                                                  .

                                                                  .

                                                                  .

                                                                  .

• 'n' element will go in row n-1 and a random column between 13 and 36

Here I attach the file, as always:

And here I show the code, which is really simple:

Test-Type Exam Correction With Java

Hello everyone!

Today's little project is a simple way of correcting tests with Java. In this piece of code I just defined two possible models or answers, they're all random, but the only thing needed is to update them with valid answers. The length of the test? I just did it for a 10-question test, but it can naturally be extended to the number of answers the teacher may want.

Here's a snapshot:

And the code:

A simple function that hides typed passwords in C++

In C++ console there's no way of hiding passwords at the same time we type them (I mean, our password remains visible for everyone who may sit next to us). There's a simple way to avoid this that resembles to what can be easily made in HTML or JavaScript: simply adding a cls command to clear all the console output until that moment and then popping up the same stuff but now with '*' instead.

Password-Decryption with C++

Hi there!
I just finished the second and last part of my little project called Encrypting&Decrypting Passwords with C++. What I show you today is the other part of the code: how to get the real password from a senseless and non-intuitive string, previously encrypted by the first program. As you may know, there are millions of ways of encrypting stuff like passwords, texts, phone numbers...strings in general. Here I show you what first came to my mind. The current program asks the user to type the encrypted password, and it recognizes whether it went through the simple-mode or advanced-mode encryption way. And that's it, it gives back the original password.

 Here are a couple of snapshots, where user chose simple-mode and the result was a string with just numbers:

and user chose advanced-mode ant the result was a string with weird characters:
