Many data cryptography methods are based on DES; these methods have a lot of disadvantages such as fixed block size, fixed private key length, multiple rounds and sometimes low level of security. In this research paper a method of secret messages cryptography will be introduced. It will be shown that the proposed method can be easily used to apply data cryptography for short, medium and long messages keeping the values of the quality parameters (MSE, PSN and CC) acceptable. The method will use three image_key to generate the required private keys needed to calculate the number of rotation digits used in character rotation. The images are to be kept in secret and it is possible to change them any time without changing the operations used in the proposed method. The proposed method will be compared with DES to show the improvements provided by the proposed method.
