File Encryption Using AES and XOR Algorithm for Data Security

The issue of Cybersecurity is paramount in today's world of the internet and data. Many organizations face the problem of the theft of confidential data and are continuously making efforts in the field of cyber security. This research work also intends to do the same and aid in the security of data in the digital world. We have seen a lot of development in the cyber security world in recent years, with attackers also getting more and more innovative with their approach to their attack on any information on the internet. The exchange of data on the internet is quite risky, as there can be unauthorized intrusion during the exchange of the data. Even if the cybercriminals hack into servers or personal devices, it can easily read the files on the system, which may be sensitive in nature. So, to maintain privacy and avoid the possible loss of privacy, techniques like encryption and decryption were introduced to encrypt confidential or sensitive files, or simply data. We intend to apply the technique of symmetric cryptography to encrypt/decrypt files that a user considers confidential. A novel approach of file encryption uses a combination of XOR and AES ciphers, which helps in creating an encrypted version of the file. This application can also decrypt the encrypted files. This concept can be used by users who want assurance that their data/files are safe and secure while on the device or while being sent to someone.
