问题描述
嗨朋友，
i使用河豚Encription algothem来获取数据。设计了一个窗口，其中包含
1.input（lable）和Textbox1
2.Output（lable和Textbox2
和两个按钮Encript和Decript。我的问题是当我在inputField中输入一些数据时输出为32bit。但我需要16位。我需要改变我的源代码。请帮助我
这是我的班级
Hi Friends,
i used blowfish Encription algothem to data encription .designed one window having
1.input(lable) and Textbox1
2.Output(lable and Textbox2
and "Two buttons" Encript and Decript. my question is when i enter some data in inputField the output come in 32bit.But i neeed 16 bit. where i have to change my source code.plese help me
