Protecting secret messages from being hacked is a vital issue. In this paper research some standard symmetric and asymmetric methods of data cryptography will be studied and a comparative analysis of these methods will be provided. A simple, highly secure and efficient method of secret messages cryptography will be introduced; the method will use a character private key with variable length. Increasing the PK length will increase the key space making the method capable to resist any attack, the produced decrypted message will be very sensitive to the PK, any changes in the PK during the decryption phase will be considered as a hacking attempt by producing a damaged decrypted message. The proposed method will be implemented using various messages; the obtained results will be analyzed to prove the quality, security and efficiency achievements provided by the proposed method.
