A CERT (Computer Emergency Response Team) is a specialised cybersecurity team dedicated to managing large-scale IT security incidents. In French, the term CERT or CSIRT (Computer Security Incident Response Team) is sometimes used.

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.
