In the digital age, security has become more critical than ever before. Security measures in information transfer and storage processes are now among the fundamental requirements. In this regard, technologies like encryption and cryptography are fundamental pillars in ensuring digital security. Encryption involves making data unreadable and transforming it into a form accessible only by authorized individuals. This process, carried out using mathematical algorithms, ensures secure transmission and storage of data. On the other hand, cryptography is a field of study that examines and develops these encryption techniques. Cryptography establishes the necessary mathematical and algorithmic foundations to ensure data security. Encryption and cryptography are widely used in various fields. Particularly in areas where sensitive information is involved, such as banking transactions, online shopping, email communication, and data transfer, the use of these technologies is common. Every transaction conducted over a secure internet connection is safeguarded through encryption and cryptography. Encryption and cryptography provide protection against threats such as cybercrime and data breaches. They address crucial issues such as safeguarding personal privacy and ensuring the security of financial transactions. Additionally, these technologies contribute to the establishment and maintenance of digital security standards. In conclusion, encryption and cryptography play a critical role in ensuring security in the digital world. These technologies enhance data security, protecting users' information, and making digital communication secure.
