Formal Definition

"Encryption is a process of maintaining data integrity and confidentiality by converting plain data into a secret code with the help of an algorithm. The corresponding reverse process is ""decryption"", a transformation that restores encrypted data to its original form. Only authorized users with a key can decrypt encrypted data. Encryption is regarded as an effective way to defend against the abuse of IT technologies, such as hacking, identity and personal data theft, fraud and the improper disclosure of confidential information. It ensures the protection of cybersecurity, data protection and privacy"
