A lot of tools have been developed to assist in the banking sector. This project work is concern in the design and implementation of computerized data encryption description system used in first bank of Nigeria Enugu branch. Computerized data encryption description system is essential to any organization. This has been previously done by manual method. But this project is aimed at computerized data encryption description system to make the work easier. This is possible because of the advance improvement in information technology as pertaining programming language; because this is achieved by the help of visual basic programming language and other programming language..
