We were inspired to add another level of security to people's data. When people share laptops or common accounts, their personal data may be vulnerable and no longer private. By encrypting your files, you can ensure that you are the only person reading your files.

What it does

Our program encrypts and decrypts local text files to ensure that the contents of your files are protected. Users select the file that they want encrypted and decrypted through a file chooser, and then simply enter a key word for the process to be completed. The decrypted or encrypted file is then available for the user to access.

How we built it

The project uses symmetric cryptography to encrypt and decrypt the data. We first wrote a sorting algorithm using a Vignère cipher that uses the basis of a keyword to shift the letters in a given file. Then, we created a graphical user interface for users to interact with the program.

Challenges we ran into

We tried to implement our project using Microsoft Azure. However, we ran into a few technical difficulties. In the end, we were not able to place our project fully on the web.

Accomplishments that we're proud of

We understood how encryption and decryption using symmetric cryptography tools can be beneficial.

What we learned

First, we learned about the variety of methods available for encryption when we were determining which one to use. Additionally, we expanded our knowledge in creating a GUI with the tools that Java provides - panels, buttons, textfields, etc.

What's next for encryptr

The next step is to implement our project through Microsoft Azure so that it can be available as a Java web application. Additionally, we can look into different methods of encryption or encrypting multiple files at once. Finally, we would be interested in adding feature that let you upload your encrypted file to the cloud automatically, for instance to Google Drive.
