DES

encryption - decryption algorithm implementation in C++ implementation in two ways

• using strings libirary
• using bits operations very fast less than 20K cpu cycles

Pre-requisites

• iostream
• bits/stdc++.h
• vector
• map
• string
• iterator
• alg
• math
• bitset
• sstream
• assert
• stdlib.h

Getting Started

• the methods are overloaded so you could either use it in strings or in the optimized way in bits operations

• get the key and text and the operation type and perform the desired operation.
