问题描述
我正在尝试使用 SecAsn1Decode 来解析以下DER编码的数据.
I'm trying to use SecAsn1Decode in order to parse the following DER encoded data.
但是，我未能为此结构定义模板(由 SecAsn1Template 表示").
However, I failed to define the template for this struct (represented by SecAsn1Template).
也许任何人都可以解释如何为以下DER结构创建模板:
perhaps anybody can explain how to create a template for the following DER structure :
这是二进制原始数据(DER格式)
here's the binary raw data (DER formatted)

推荐答案
这是DER/BER TLV数据.
It is DER/BER TLV data.
以下是使用 https://iso8583.info/解析的详细数据lib/ISO/8825/1/BER/TLVs
