I'm trying to use SecAsn1Decode in order to parse the following DER encoded data.
However, I failed to define the template for this struct (represented by SecAsn1Template).
perhaps anybody can explain how to create a template for the following DER structure :
here's the binary raw data (DER formatted)
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
6D
and here's the interpretation of this data using asn1 java decoder https://lapo.it/asn1js
