20.3 – Planning & Managing Security Assessment & Testing
Cryptography & Steganography Cryptography is the method of hiding information and it is used when communicating over an authorized platform like the internet, where information is required to be secured from other third parties. Modern cryptography focuses on emergent cryptographic algorithms that are tough to break by an opponent because of computational resistance, and consequently could not be broken by a sensible means. Modern cryptography is classified in three types of cryptographic algorithms such as Symmetric key cryptography, Public-key cryptography and hash functions. Symmetric key cryptography contains encryption techniques where both the sender and the receiver share the same key…
