In cryptography, Encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot. Encryption does not itself prevent interference, but makes it harder for the would-be interceptor to access the content. It is also used to protect data in transit.
Encryption has long been used by militaries and governments to facilitate secret communication. It is now commonly used in protecting information within many kinds of civilian systems. Types of Encryption include symmetric-key and public-key encryption. In response to Encryption, cyber-interceptors and adversaries have developed new types of attacks, including: cryptographic attacks, stolen ciphertext attacks, attacks on Encryption keys, data corruption or integrity attacks, data destruction attacks, and ransomware attacks.
