Definition
Encryption is the process of transforming data into a form that cannot be read by anyone without the appropriate cryptographic keys.
Human Explanation
Encryption means that even if someone gains access to data, they cannot read it without the correct key.
Why it Matters
Encryption protects the confidentiality of data while it is stored and while it is transmitted.
Conceptual Boundary
Encryption does not replace Access Control, Backup or other security mechanisms.
Practical Perspective
The effectiveness of Encryption depends not only on the algorithm but also on appropriate management of cryptographic keys.
