无法删除 Java 个卡片小程序
Cannot delete Java Card applet
我是 Java Card 的新手，但经过一些阅读后，我的第一个 Applet 运行良好......直到今天。我进行了一些重构，并在我的 Applet 中插入了一个 OwnerPIN 对象。现在我可以写一次Applet，但是第二次，删除就不起作用了。
这是我的输出：

我的卡被冻结了吗？我可以看到我的 AID 在状态 7 下运行...这是什么意思。它是否连接到我的 OwnerPIN 对象？
感谢您的帮助！
一月
有问题的是这一行：
private static byte[] testdata;
请记住，static 对持久对象的引用是邪恶和危险的。它们始终存在，即使在 Applet 实例被卸载并被垃圾收集后也是如此。这就是为什么永远不会对引用的对象（在您的情况下为字节数组）进行垃圾回收，永远不会释放持久内存，因此删除命令失败的原因。
如果可以避免使用 static 引用，这样做。
如果无法避免，使用AppletEvent接口：
public final class MyApplet extends Applet implements AppletEvent {
private static byte[] testdata;
...
//This method is called in the moment of uninstallation
public final void uninstall() {
testData = null; //release the reference --> testData can be GC
}
...
}
我把你的小程序安装在两个不同的JavaCards上，然后我删除了它，然后又一次又一次地成功安装。
首先请下载GlobalPlatformPro工具。 （它是免费的，如果您在 Windows 平台上工作，那么 gp.exe 就足够了。）
下载后在命令行中尝试这些命令：
列出您安装的小程序及其软件包 AID：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -list
AID: A000000151000000 (|....Q...|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
AID: 010203040503 (|......|)
App SELECTABLE: (none)
AID: A0000001515350 (|....QSP|)
ExM LOADED: (none)
A000000151535041 (|....QSPA|)
AID: 0102030405 (|.....|)
ExM LOADED: (none)
010203040503 (|......|)
请注意，在上面的输出中，那些标记为 App 的 AID 是小程序，那些标记为 ExM 的 AID 是 Executable Modules(包裹).
结果中的0102030405和010203040503是我卡中你程序的Pack AID和App AID。
单独删除包，不删除其小程序：
如果我尝试在不删除其小程序的情况下删除程序包，则会失败并且我会收到与您收到的相同的错误消息：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -delete 0102030405
Could not delete AID: 0102030405
TIP: Maybe try with --deletedeps
pro.javacard.gp.GPException: Deletion failed SW: 6985
at pro.javacard.gp.GlobalPlatform.check(GlobalPlatform.java:1092)
at pro.javacard.gp.GlobalPlatform.deleteAID(GlobalPlatform.java:867)
at pro.javacard.gp.GPTool.main(GPTool.java:390)
有两种删除方式：
- 先删除小程序，再删除包。
- 删除包及其所有依赖项（包括小程序）。
同时删除包和小程序：
我选择第二种方案（删除命令中增加了一个参数-deletedeps）：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -delete 0102030405 -deletedeps
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -list
AID: A000000151000000 (|....Q...|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
AID: A0000001515350 (|....QSP|)
ExM LOADED: (none)
A000000151535041 (|....QSPA|)
再次为包和小程序安装具有相同 AID 的相同小程序：
如您所见，您的包和小程序已被删除。现在我再次安装它：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -install C:\NetBeansProjects\test2\dist\test2.cap
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -list
AID: A000000151000000 (|....Q...|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
AID: 010203040503 (|......|)
App SELECTABLE: (none)
AID: A0000001515350 (|....QSP|)
ExM LOADED: (none)
A000000151535041 (|....QSPA|)
AID: 0102030405 (|.....|)
ExM LOADED: (none)
010203040503 (|......|)
嗯，如你所见，小程序又安装成功了
请注意，您必须将我卡的身份验证密钥替换为您卡的身份验证密钥（我的意思是将 404142...4f 替换为您卡的密钥）
无论如何，如果您在第一步（列出已安装的小程序）中遇到 0x6985 错误，这意味着您的密钥不正确。例如，如果我在命令中为 key 参数输入一个随机数，我将面临这个结果：
G:\BasicTestTools\SmartCardTools>gp -key 00112233445566778899aabbccddeeff -list
pro.javacard.gp.GPException: STRICT WARNING: Card cryptogram invalid!

at pro.javacard.gp.GlobalPlatform.openSecureChannel(GlobalPlatform.java:515)
at pro.javacard.gp.GPTool.main(GPTool.java:371)
如输出中所示，您对 key 的值的尝试次数有限。通常在 10 次错误尝试后，您的卡将被锁定并且锁定生命周期不可逆转。
我是 Java Card 的新手，但经过一些阅读后，我的第一个 Applet 运行良好......直到今天。我进行了一些重构，并在我的 Applet 中插入了一个 OwnerPIN 对象。现在我可以写一次Applet，但是第二次，删除就不起作用了。 这是我的输出：

有问题的是这一行：
private static byte[] testdata;
请记住，static 对持久对象的引用是邪恶和危险的。它们始终存在，即使在 Applet 实例被卸载并被垃圾收集后也是如此。这就是为什么永远不会对引用的对象（在您的情况下为字节数组）进行垃圾回收，永远不会释放持久内存，因此删除命令失败的原因。
如果可以避免使用 static 引用，这样做。
如果无法避免，使用AppletEvent接口：
public final class MyApplet extends Applet implements AppletEvent {
private static byte[] testdata;
...
//This method is called in the moment of uninstallation
public final void uninstall() {
testData = null; //release the reference --> testData can be GC
}
...
}
我把你的小程序安装在两个不同的JavaCards上，然后我删除了它，然后又一次又一次地成功安装。
首先请下载GlobalPlatformPro工具。 （它是免费的，如果您在 Windows 平台上工作，那么 gp.exe 就足够了。）
下载后在命令行中尝试这些命令：
列出您安装的小程序及其软件包 AID：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -list
AID: A000000151000000 (|....Q...|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
AID: 010203040503 (|......|)
App SELECTABLE: (none)
AID: A0000001515350 (|....QSP|)
ExM LOADED: (none)
A000000151535041 (|....QSPA|)
AID: 0102030405 (|.....|)
ExM LOADED: (none)
010203040503 (|......|)
请注意，在上面的输出中，那些标记为 App 的 AID 是小程序，那些标记为 ExM 的 AID 是 Executable Modules(包裹).
结果中的0102030405和010203040503是我卡中你程序的Pack AID和App AID。
单独删除包，不删除其小程序：
如果我尝试在不删除其小程序的情况下删除程序包，则会失败并且我会收到与您收到的相同的错误消息：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -delete 0102030405
Could not delete AID: 0102030405
TIP: Maybe try with --deletedeps
pro.javacard.gp.GPException: Deletion failed SW: 6985

at pro.javacard.gp.GlobalPlatform.deleteAID(GlobalPlatform.java:867)
at pro.javacard.gp.GPTool.main(GPTool.java:390)
有两种删除方式：
- 先删除小程序，再删除包。
- 删除包及其所有依赖项（包括小程序）。
同时删除包和小程序：
我选择第二种方案（删除命令中增加了一个参数-deletedeps）：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -delete 0102030405 -deletedeps
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -list
AID: A000000151000000 (|....Q...|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
AID: A0000001515350 (|....QSP|)
ExM LOADED: (none)
A000000151535041 (|....QSPA|)
再次为包和小程序安装具有相同 AID 的相同小程序：
如您所见，您的包和小程序已被删除。现在我再次安装它：
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -install C:\NetBeansProjects\test2\dist\test2.cap
G:\BasicTestTools\SmartCardTools>gp -key 404142434445464748494a4b4c4d4e4f -list
AID: A000000151000000 (|....Q...|)
ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management
AID: 010203040503 (|......|)
App SELECTABLE: (none)
AID: A0000001515350 (|....QSP|)
ExM LOADED: (none)
A000000151535041 (|....QSPA|)
AID: 0102030405 (|.....|)
ExM LOADED: (none)
010203040503 (|......|)
嗯，如你所见，小程序又安装成功了
请注意，您必须将我卡的身份验证密钥替换为您卡的身份验证密钥（我的意思是将 404142...4f 替换为您卡的密钥）
无论如何，如果您在第一步（列出已安装的小程序）中遇到 0x6985 错误，这意味着您的密钥不正确。例如，如果我在命令中为 key 参数输入一个随机数，我将面临这个结果：
G:\BasicTestTools\SmartCardTools>gp -key 00112233445566778899aabbccddeeff -list
pro.javacard.gp.GPException: STRICT WARNING: Card cryptogram invalid!

如输出中所示，您对 key 的值的尝试次数有限。通常在 10 次错误尝试后，您的卡将被锁定并且锁定生命周期不可逆转。
