Vb编程编写一个小程序,可以对输入的加密评测文章源码一段英文字符串进行加密和解密,加密算法中需要使用到学号后两位
以下是源码修改webview源码根据学号末2位加密、解密的加密健康问诊 源码VB程序:Private Sub Form_Click()
x = Val(Right(Text1.Text, 2)) '取学号末2位
'以下是加密
s = Text2.Text
s1 = s
For i = 1 To Len(s)
c = Mid(s1, i, 1)
Mid(s1, i, 1) = Chr(Asc(c) Xor x)
Next i
Text3.Text = s1
'以下是解密
s = s1
For i = 1 To Len(s)
c = Mid(s, i, 1)
Mid(s, i, 1) = Chr(Asc(c) Xor x)
Next i
Text4.Text = s
End Sub

strIN = Replace(strIN, "KBK", " ") '空格处理
num = Len(strIN)
For i = 1 To num
strp = Mid(strIN, i, 1) '取得自符
j = InStr(1, sec, strp)
If j < 0 Then
'保留原来字符
Debug.Print "*" & strp & "*"
Else
strp = Chr(j + Asc("a") - 1)
End If
strOUT = strOUT & strp
Next i
