This document describes a model for encrypting text using genetic algorithms. The model involves: 1. Extracting blocks from the text and performing crossover and mutation operations on the blocks based on randomly generated points. 2. Generating a symmetric encryption key based on the crossover and mutation points. 3. Encrypting the text blocks using the key. The model is implemented in a prototype to test its feasibility. The prototype encrypts text accurately based on the genetic algorithm operations.
