Implementation and enhancement Affine cipher of database

الملخص EN

: The first of this paper, Caeser cipher is used to encrypt the fields in data base.

The keys have been used from different lengths of fields, then applying affine algorithm.

This is given a layer of security for data base.

The cipher text is stored as a raw data in text file, which is separated between fields by Semicolon.

The process is continued to end of records.

The second part is creating a new Data Access Object(DAO), tables, records, fields, through counting a number of semicolon in a raw.

The program keeps going until obtaining original records.
