我正在尝试使用直接XML格式的C#签署Microsoft Office Word文件。
这里有一些问题和模棱两可,如:
SignatureValue
?最后一个问题是我这样做了吗?也许这里有问题,我错过了一个软件包,否则它本身就会与openxml文件进行交互并签名。
但请记住,我实际上是尝试使用外部令牌签署数据,该外部令牌具有可用的pkcs11接口(但没有CSP),因此我使用PKCS11 Interop库将其迁移到c#,但我仍然是这里有点困惑。
只是为了抬头任何执行openXML交互的库也应该允许我使用pkcs11命令对文档进行签名(即,它给我字节流进行签名和消化,但是其他部分本身,pkcs11真的不应该是在这里被认为是重要的(你可以用我的自定义算法替换它))
BTW XML中的签名构建器如下所示:
<?xml version="1.0" encoding="UTF-8"?>
