如何使用 SignedCode

Question

你好最近我看到了有关CAPICOM的 https://learn.microsoft.com/it-it/windows/win32/seccrypto/signedcode?redirectedfrom=MSDN#methods 和其他文件.dll

如何调用此 DLL/activeX？

我有方法和属性，但我如何调用 SignedCode -> SignCode.verify.......

Note：此问题总结整理于:How to use SignedCode - Microsoft Q&A

Answer

您好，您必须首先添加对 CAPICOM 的引用，然后像（此处的代码）一样使用它。


    Dim signeddata As CAPICOM.SignedData = New CAPICOM.SignedData()  
    Dim file As FileStream = File.Open(tbSourceFile.Text, FileMode.Open)  
    Dim Content As Byte() = New Byte(CInt(file.Length) - 1) {}  
    file.Read(Content, 0, CInt(file.Length))  
    file.Close()  
    Dim sw As StringWriter = New StringWriter()  
    sw.Write(Content)  
    signeddata.Content = sw.ToString()  
    Dim store As IStore = New CAPICOM.Store()  
    store.Open(CAPICOM.CAPICOM_STORE_LOCATION.CAPICOM_CURRENT_USER_STORE, "MY", CAPICOM.CAPICOM_STORE_OPEN_MODE.CAPICOM_STORE_OPEN_READ_ONLY Or CAPICOM.CAPICOM_STORE_OPEN_MODE.CAPICOM_STORE_OPEN_EXISTING_ONLY)  
    Dim certificates As ICertificates2 = CType(store.Certificates, ICertificates2)  
    certificates = certificates.Find(CAPICOM_CERTIFICATE_FIND_TYPE.CAPICOM_CERTIFICATE_FIND_KEY_USAGE, CAPICOM_KEY_USAGE.CAPICOM_DIGITAL_SIGNATURE_KEY_USAGE, True)  
  
    If certificates.Count > 0 Then  
        certificates = certificates.[Select]()  
    End If  
  
    If certificates.Count > 0 Then  
        Dim signers As ISigner2 = New CAPICOM.Signer()  
        signers.Certificate = certificates(1)  
        tbSignatureBlock.Text = signeddata.Sign(signers, True)  
    End If
