徐氏文本加密 app for iPhone and iPad

Professional Mail, SMS, Notes, Facebook, Twitter and other text information encryption and decryption application software.

The 21st century, With the rapid development of computer technology,  people are increasingly inseparable from computer and network,  information fills with peoples lives, and relates to personal privacy,so people increasingly pay more attention on security issues.
How to ensure the information on the transmission of  the network will not be pried? Obviously, the safest way is to transmit encrypt information, receiver use the same software and the same password to unlock the information.
The biggest feature of this application is not only user can input a  password which contains a length of any character (including Chinese),but also the application can open the built-in  second password, which doubles the difficulty of the crack,enhances the safety factor greatly.
Of course, while the safety factor is increasing,  the length of the ciphertext encrypted will increase. But at the present ,the machine performance, the speed of the network, it can be ignored, after all, safety is more important.

After the default encryption: TpkCEd6oULiJuRgJ7iYAYHZsAsbEWNWwS/3SwWnKbxE=
