Encryption

Encryption is a fundamental security technique used to protect sensitive data by converting it into a coded format that can only be read or decoded by someone who has the correct decryption key. This process, essential for safeguarding data against unauthorized access, involves the use of algorithms to scramble the data at its source, such as a terminal or computer, before it is transmitted over networks or stored.

The primary purpose of encryption is to ensure the confidentiality and integrity of data as it moves across the internet or other networks, or while it is stored on computers, servers, or mobile devices. By encrypting data, organizations can prevent fraud and secure personal and financial information from cyber threats, including hacking and data breaches.

Common uses of encryption in the digital world include securing emails, safeguarding sensitive transaction data in online banking and e-commerce, and protecting personal data on mobile devices. As cyber threats evolve, the role of encryption in cybersecurity continues to grow, making it a critical component of modern data protection strategies.
