简易文本加密vb程序，通过让每个字符的Ascll码都加上一个随机数来达到加密目的。目前功能不是很完善，就当作是自娱自乐的小游戏好了。如果出现了bug，希望指出。(The simple text encrypts the VB program by adding a random number to the Ascll code of each character to achieve the encryption purpose. At present, the function is not very perfect, just as a small game of self amusement. If bug appears, I hope to point out.)
