A simple and easy to implement method of secret message cryptography will be introduced. The message to be encrypted-decrypted is to be converted to binary matrix, this matrix is to be reshaped to 16 columns matrix, and the contents of this matrix will be rearranged base on the contents of the generated indices key. A chaotic paramaters included in the private key will be used to run a chaotic logistic map model to generate a 16 elements chaotic key, this key will be sorted to get the required indices key. The proposed method will be flixeble and it will be used to encrypt-decrypt any message with any length. Changing the message or/and changing the key will not affect the method. The produced decrypted message will be sensitive to the selected PK, any changes in the private key in the decryption process will produce a carrupted unreadable message. The proposed method will be tested and implemented using various in sizes messages, the obtained result will be used to prove the sensitivity, quality and efficiency of the proposed method.
