It is no secret that for the important role of security of information in the life, especially after the massive information revolution of the past years. There are unremitting efforts to protect the information and communication channels. The great development in the field of protection is negotiable by growing of opposite stream that works on penetration, breaking codes and getting confidential information in any way. This paper discusses one of public encryption modes (Knapsack) then provides a way to break it through the use of a genetic algorithm manner deviate from the classics researches published in this field. The proposed system proved well-deserved break the cipher generated by Knapsack method because of using a new fitness function in addition to a new vision in the using of genetic algorithm in this problem as a whole.
