Go Requires Chilkat v11.4.0+

Example: Mime.GetDecryptCertInfo method

Demonstrates the GetDecryptCertInfo method. Go

    success := false

    mime := chilkat.NewMime()

    //  Load MIME that is has Content-Type like this:
    //  Content-Type: application/pkcs7-mime; smime-type="enveloped-data"; name="smime.p7m"; smime-type="enveloped-data"
    success = mime.LoadMimeFile("qa_data/mime/enveloped_data.eml")
    if success == false {
        fmt.Println(mime.LastErrorText())
        mime.DisposeMime()
        return
    }

    //  Get information about the certificate that would be needed to decrypt.
    //  An enveloped-data can potentially be decrypted by multiple certificates if it was encrypted in a way that allows it,
    //  but in most cases, only a single certificate with associated private key (that of the message recipient) is possible.
    json := chilkat.NewJsonObject()
    success = mime.GetDecryptCertInfo(json)
    if success == false {
        fmt.Println(mime.LastErrorText())
        mime.DisposeMime()
        json.DisposeJsonObject()
        return
    }

    json.SetEmitCompact(false)
    fmt.Println(*json.Emit())

    //  Sample output:

    //  {
    //    "recipientInfo": [
    //      {
    //        "serial": "****",
    //        "issuerCN": "****"
    //      }
    //    ]
    //  }

    //  Get each certificate's information like this:
    var serial *string = new(string)
    var issuerCN *string = new(string)

    i := 0
    count := json.SizeOfArray("recipientInfo")
    for i < count {
        json.SetI(i)
        serial = json.StringOf("recipientInfo[i].serial")
        issuerCN = json.StringOf("recipientInfo[i].issuerCN")
        i = i + 1
    }


    mime.DisposeMime()
    json.DisposeJsonObject()
