security - 使用 SecAsn1Decode 解析 DER 格式数据
问题描述
我正在尝试使用SecAsn1Decode以解析以下 DER 编码数据。
但是，我没有为这个结构定义模板（用 表示SecAsn1Template）。
也许任何人都可以解释如何为以下 DER 结构创建模板：
这是二进制原始数据（DER 格式）
30 81 8E 31 0B 30 09 06 03 55 04 06 13 02 49 4C
31 0F 30 0D 06 03 55 04 08 0C 06 69 73 72 61 65
6C 31 0C 30 0A 06 03 55 04 07 0C 03 54 4C 56 31
0B 30 09 06 03 55 04 0A 0C 02 54 53 31 1E 30 1C
06 03 55 04 0B 0C 15 43 41 5F 63 65 72 74 69 66
69 63 61 74 65 5F 73 65 72 76 65 72 31 1B 30 19
06 03 55 04 03 0C 12 61 61 61 61 61 61 61 4D 61
63 42 6F 6F 6B 5F 50 72 6F 31 16 30 14 06 09 2A
86 48 86 F7 0D 01 09 01 16 07 7A 40 7A 2E 63 6F

这是使用 asn1 java 解码器https://lapo.it/asn1js对此数据的解释

解决方案
它是 DER/BER TLV 数据。
这是使用https://iso8583.info/lib/ISO/8825/1/BER/TLVs解析的详细数据
