Question

我已经使用java 8签署了一个没有问题的XML文档，直到我升级到 Java 8u121 版本，代码是：

   signature.sign(dsc)

错误在代码行中：

javax.xml.crypto.XMLSignatureException: java.security.InvalidKeyException: Invalid RSA private key

错误是：

Sub Mail_Selection_Range_Outlook_Body()
'For Tips see: http://www.rondebruin.nl/win/winmail/Outlook/tips.htm
'Don't forget to copy the function RangetoHTML in the module.
'Working in Excel 2000-2016
    Dim rng As Range
    Dim OutApp As Object
    Dim OutMail As Object

    Set rng = Nothing
    On Error Resume Next
    'Only the visible cells in the selection
    Set rng = Selection.SpecialCells(xlCellTypeVisible)
    'You can also use a fixed range if you want

    On Error GoTo 0

    If rng Is Nothing Then
        MsgBox "The selection is not a range or the sheet is protected" & _
               vbNewLine & "please correct and try again.", vbOKOnly
        Exit Sub
    End If

    With Application
        .EnableEvents = False
        .ScreenUpdating = False
    End With

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    On Error Resume Next
    With OutMail
        .To = "ron@debruin.nl"
        .CC = ""
        .BCC = ""
        .Subject = "This is the Subject line"
        .HTMLBody = RangetoHTML(rng)
        .Send   'or use .Display
    End With
    On Error GoTo 0

    With Application
        .EnableEvents = True
        .ScreenUpdating = True
    End With

    Set OutMail = Nothing
    Set OutApp = Nothing
End Sub

...

对于Java 8u121之前的版本，不要发生任何错误。

这是由JDK 8u121（http://www.oracle.com/technetwork/java/javase/8u121-relnotes-3315208.html）＆＃34中的修复引起的错误; DER编码解析代码中添加了更多检查更多检查添加到DER编码解析代码中以捕获各种编码错误。此外，包含构造的无限长度编码的签名现在将在解析期间导致IOException。请注意，使用JDK默认提供程序生成的签名不受此更改的影响。 JDK-8168714（不公开）＆＃34;

JDK-8175251（https://bugs.openjdk.java.net/browse/JDK-8175251）已经修复了这个问题，将在下一次JDK更新中提供。该修复已经在JDK 8u152中，其早期访问版本可以从https://jdk8.java.net/download.html
