A. Initial encryption algorithm
The initial encryption algorithm is based on characters in the plaintext, disguise the real information with the help of calculating ASCII code values of different characters, in order to prevent being cracked easily. At the same time, improve the system encryption to protect the safety factor.
In the general software system encryption process, the
plaintext is composed of Capital letters, lower case letters, Arabic numbers and other special characters. Therefore, we need to deal with different types of characters transform
