🙍 About Microsoft Visual Studio:
Visual Studio is an integrated development environment from Microsoft. It is used to develop computer programs including websites, web apps, web services and mobile apps

🙍 About C#:
C# is a general-purpose high-level programming language supporting multiple paradigms. C# encompasses static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented, and component-oriented programming disciplines.

🙍 About Cryptography:
Cryptography, or cryptology, is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

🙍 About IV (Initialization Vector)
In cryptography, an initialization vector (IV) or starting variable is an input to a cryptographic primitive being used to provide the initial state. The IV is typically required to be random or pseudorandom, but sometimes an IV only needs to be unpredictable or unique.

🙍 About Cryptographic Salt:
A cryptographic salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords. Salts help us mitigate hash table attacks by forcing attackers to re-compute them using the salts for each user.

🙍 About Rfc2898DeriveBytes (.NET Class):
Implements password-based key derivation functionality, PBKDF2, by using a pseudo-random number generator based on HMACSHA1.
