DPAPI加密与my.settings不兼容 [英] DPAPI encryption not working so well with my.settings

问题描述

当my.settings.datastorage没有任何内容时，这样可以正常工作。但是在我经历了两次之后，它给了我一个错误

when my.settings.datastorage has nothing in it, this works fine. but after i go through this twice, it gives me an error

total_string = "some string"
My.Settings.datastorage = My.Settings.datastorage & DPAPI.Encrypt(total_string)
My.Settings.Save()
MsgBox(DPAPI.Decrypt(My.Settings.datastorage))

这是它给出的错误：

Base-64字符串中的字符无效。

"Invalid character in a Base-64 string."

推荐答案

您不能简单地将加密字符串连接到& amp;;如果您以后要解码它们，则不能。为了添加信息，您必须解码您已经拥有的信息，将清晰的文本合并到编码中。

You can't simply concatenate encrypted strings with &, not if you want to decode them later anyway. In order to Add information you'll have to decode what you've already got, combine the clear text en encode the total.
