我想知道如何通过 vb.net 代码加密电子邮件地址。
我发现一个样本不能很好地处理特殊字符，我收到了这个错误：
The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.
这是我正在尝试的代码：
'The function used to encrypt the text
Private Function Encrypt(ByVal strText As String, ByVal strEncrKey _
As String) As String
Dim byKey() As Byte = {}
Dim IV() As Byte = {&H12, &H34, &H56, &H78, &H90, &HAB, &HCD, &HEF}
Try
byKey = System.Text.Encoding.UTF8.GetBytes(Left(strEncrKey, 8))
Dim des As New DESCryptoServiceProvider()
Dim inputByteArray() As Byte = Encoding.UTF8.GetBytes(strText)
Dim ms As New MemoryStream()
Dim cs As New CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write)
cs.Write(inputByteArray, 0, inputByteArray.Length)
cs.FlushFinalBlock()
Return Convert.ToBase64String(ms.ToArray())
Catch ex As Exception
Return ex.Message
End Try
End Function
你们有什么感想？我究竟做错了什么？谢谢，拉齐尔
更新：全栈跟踪：
System.FormatException 被捕获 Message=输入不是有效的 Base-64 字符串，因为它包含非 base 64 字符、两个以上的填充字符或填充字符中的非空白字符。Source=mscorlib StackTrace：在 D:\Website\Account\Login.aspx.vb:line 213 InnerException 中的 WEbsite.Login.Decrypt(String strText, String sDecrKey) 处的 System.Convert.FromBase64String(String s)：

加密方式增加：
