我想用vb加密一个jpg格式的图片文件，应该如何实现呢，不需要多少复杂的加密，只需要普通的图片软件无法打开就可以了，加密之后还可以重新还原[此贴子已经被作者于2016-11-25 15:32编辑过]
复杂一点的话，可以尝试API（这个是我从范例里找到，没有用过，你自己研究一下）
程序代码：Private Declare Function icePub_encryptFile Lib "icePubDll.dll" (ByVal strFilename As String,ByVal strOutputFilename As String, ByVal strKey As String) As Integer
Private Declare Function icePub_decryptFile Lib "icePubDll.dll" (ByVal strFilename As String, ByVal strOutputFilename As String, ByVal strKey As String) As Integer
strkey ="This is a key"
'加密
a2=icePub_encryptFile("e:\a.jpg","e:\a.dat",strkey )
'解密
a2 = icePub_decryptFile("e:\a.dat", "e:\a.jpg", strkey )
