Dim buffer As Byte() = Convert.FromBase64String(encryptedtext

请问这句话是什么意思？

Base64

也能用一个密匙进行加密吗？

是指把字符串encryptedtext传唤为由基为64数值字节数组.
而会被转换的字符只包括,大写字符“A”到“Z”、小写字符“a”到“z”、数字“0”到“9”以及符号“+”和“/”。空白字符及其 Unicode 名称和十六进制码位为：制表符（CHARACTER TABULATION，U+0009）、换行符（LINE FEED，U+000A）、回车符（CARRIAGE RETURN，U+000D）和空格符（SPACE，U+0020）。

这和加密没什么关系.不过这样转换后方便加密运算.

Dim a As Integer, b As Integer, c As Integer, aa As Integer, bb As Integer dim s as string Dim hstr As String * 1 Dim i As Integer,j As Integer vb DIM A$,B%? Dim Number1 As Single, Number2 As Single, Result As Single Dim rs As New ADODB.Recordset Dim adorecordset As New ADODB.Recordset VB中Dim workstation As workspace 是什么意思？ Dim rttitle As String * 256是什么意思
