Encryption, also known as cryptography in everyday language although this term is inappropriate, is a technique which consists of transforming understandable data, known as plaintext data, into an unreadable and incomprehensible format, known as encrypted data, using mathematical algorithms and one or more encryption keys.
This transformation ensures that only people with the decryption key (or the corresponding keys in the case of two-key systems) can read and understand the original content.
The aim is to protect the confidentiality, integrity and sometimes authenticity of information, by preventing it from being consulted or modified by unauthorised persons.
