Cryptography - Data Security

This App covers the basics of the science of cryptography. It explains how programmers and network professionals can use cryptography to maintain the privacy of computer data. Starting with the origins of cryptography, it moves on to explain cryptosystems, various traditional and modern ciphers, public key encryption, data integration, message authentication, and digital signatures

Types of Cryptography

1. Symmetric Key Cryptography (Secret Key Cryptography)

2. Asymmetric Key Cryptography (Public Key Cryptography)

3. HASH FUNCTION

This useful App lists 150 topics with detailed notes, diagrams, equations, formulas & course material, the topics are listed in 5 chapters. The app is must have for all the engineering science students & professionals.
