Abstract: Cryptography is an imperative tool for protecting and securing data. Security provides safety and reliability. Genetic Algorithm (GA) is typically used to obtain solution for optimization and search problems. This paper presents application of GA in the field of cryptography. Key Selection in public key cryptography is a selection process in which keys can be categorized on the basis of their fitness, making GA a good candidate for key generation. Primary goals of our algorithm was to provide fast and improved performance results having practical and feasible implementation. GA correlates nature to a great extent and produce population of keys such that keys with higher fitness value is replicated often. Good Fitness function helps in exploring search space more efficiently and effectively while bad fitness function traps GA operating in local optimum solution and losing its discovery power. Pearson’s Coefficient of auto-correlation was used to calculate the fitness of keys. Ranking of keys was performed to find the best fit key. The private key generated cannot be derived from public key. The key samples satisfy gap and frequency test. Thus, purely random and non-repeating final keys were obtained by application of GA which increased the keys strength and security.
