Cryptology is a thriving research area of great practical importance. It is a fundamental building block of communications security. Cryptographic techniques currently being utilized in the field of communication. This paper presents an approach for the heuristic search procedures for cryptanalysis and development of enhanced cryptographic techniques. To implement the proposed Tabu search, genetic, and simulated annealing algorithms firstly by utilizing cipher text as well as some plain text and secondly by using only the cipher text to retrieve the original data.
