Abstract
Privacy and security in our digital environment have become essential today. Some data stored on hard disks, in flash memory, or exchanged through our communication channels is sensitive and should be kept confidential. Additionally, documents containing confidential information, such as business algorithms or new application coding, require adequate measures to ensure privacy and security. Therefore, data encryption is crucial in protecting information from being intercepted, misused, or stolen. While encryption tools are available for business e-mails, using these tools often requires subscribing as a member and paying extra fees. Effective tools are not limited to e-mail alone. Still, they can also be applied to any text data that requires a high level of security and complexity to ensure the protection of the data for a duration longer than it needs to be safeguarded. Our research aims to develop a stand-alone application that encrypts data to ensure its confidentiality without additional subscriptions or fees. The application is designed to be user-friendly, with fast encryption and decryption capabilities. It can be used not only for encrypting and decrypting e-mail messages but also for programming languages and Excel data. The application development utilizes techniques such as Diffe-Hellman, Mersenne Twister, and AES, arranged in layers to generate complex ciphertext that is difficult to decrypt without the developed application. LabVIEW was used for testing encryption speed. The attempt to attack encrypted data was subjected, but the result yielded no successful key retrieval.
