EFTS: An encryption file transfer system applying advanced encryption standard (AES) algorithm

Since the start of the Covid19 pandemic, most of the work has been done online, including teaching, consulting, and exchanging confidential data between coworkers. Transferring data over the internet, on the other hand, is always risky. Some data can be lost or delivered to the wrong person by mistake. When a worker types in an email address to send a confidential attachment, they might type in a letter or a number by mistake that will send the email to another person. If the data ends up in the wrong hands, the company can suffer a significant loss. Therefore, encryption is important in case an unauthorized user obtains access to the data, they will be unable to read it due to encryption. It secures sensitive data as well as increases the reliability of client-server communication. EFTS is an encryption file transfer system, developed to ensure safe and secure data transferring over the internet and to reduce the impact caused to companies in case of a human error.
