我正在努力理解如何为智能卡创建一个CDOL1,而applet开发人员对此却没有多大帮助。当我向卡片发送GET处理选项命令时,我得到以下响应:
80 0E 7D 00 40 01 01 00 48 01 03 01 50 01 03 00 90 00
我一直试图了解什么是7D模板,以及我应该如何构建CDOL,但到目前为止还没有发现什么。我希望有更多经验的人能帮我。

获取处理选项
根据"-应用规格",标签0x80格式1回复包含以下GET处理选项:
请记住,对于不同的APDU命令,标签0x80格式是不同的。
使用EMV标记0x80格式1的APDU数据答复包含(2字节) AIP和AFL,其中包含3条记录(各4字节,总计12字节):
TLVs: # EMV, Tag + Length + Value (TLV) series

数据对象列表(DOL)
EMV数据对象列表(DOL)的格式定义在同一个EMV 3中。在EMV中使用了几个DOL标记。样本:
所有DOL标记都遵循相同的格式规则--标记值包含Series of Tag_ID + Length字节,没有值部分。
该示例具有CDOL1标记0x8C、长度0x15 (21个字节)和值解析。

CDOL1标签描述了标签的列表及其长度,实际值需要包含在首先生成应用程序加密(AC) APDU请求数据中。
生成应用密码(AC)
第一次生成AC命令的SmartCard APDU请求数据包含CDOL1中提到的系列值。用于第二次生成AC的CDOL2。
下面是在响应中生成AC APDU命令和标签0x80格式1模板的示例(与Generate命令相关)。
