使用ClosedXML加密Excel文件

[英]Encrypt excel file using ClosedXML

原文 2018-07-13 08:23:55 5 1 c#/ excel/ password-protection/ closedxml

We are using ClosedXML library to generate our excel reports. 我们正在使用ClosedXML库来生成我们的Excel报告。 A new requirement form client is to password protect reports marked as confidential. 客户端的一项新要求是使用密码保护标记为机密的报告。 There is a method XLWorkbook.Protect() with some overloads, however, none of it is encrypting a file, just locking structure at best. 有一个带有一些重载的XLWorkbook.Protect（）方法，但是，它没有一个在加密文件，最多只是锁定结构。 In other words, you can still see data after opening a file, MS Excel will not ask you for a password. 换句话说，打开文件后您仍然可以看到数据，MS Excel不会要求您输入密码。

Is ClosedXML even supporting excel file encryption? ClosedXML甚至支持excel文件加密吗？ On their wiki which I found on GitHub, there is the only article about protecting sheets and even for formatting and structure. 在我在GitHub上找到的他们的Wiki上，只有关于保护工作表，甚至用于格式和结构的文章。
Was anyone able to find a way with ClosedXML? 有谁能够找到ClosedXML的方法吗？ We would like to avoid using another library (like Spire.XSL; Microsoft.Office.Interop.Excel is not an option) if possible. 如果可能的话，我们希望避免使用其他库（例如Spire.XSL；不是Microsoft.Office.Interop.Excel）。

Thanks 谢谢

After some try/fails and code disassembling I realized that ClosedXML is not supporting encryption at all; 经过几次尝试/失败和代码分解后，我意识到ClosedXML根本不支持加密；它只支持加密。 at least I was unable to find trace of it. 至少我找不到它的踪迹。 Maybe they will add it later. 也许他们稍后会添加。 We were able to convince client to give us a time to refactor the code and we are using EPPlus now. 我们能够说服客户给我们一些时间来重构代码，我们现在正在使用EPPlus。
