Data encryption achieves the critical goal of protecting sensitive information from unauthorized access or breach during transmission and storage. By converting data into a coded format, encryption ensures that only authorized users possessing the appropriate decryption keys can access the original information. This process is fundamental to maintaining data integrity and privacy in various applications, particularly in financial transactions, online communications, and cloud storage. With increasing concerns over data security, encryption is essential to safeguarding personal and corporate data against cyber threats and malicious attacks.
