What Hacker News says
4 sourcesHello, nice to find people interested in ASN1 ! But, one of the first lessons I learned in programming is to not reinvent the wheel. I just want to understand what's your motivation behind this project, is it for personal curiosity/discover the protocol or something else ? Because there is already a seemingly good ASN1 compiler in C : https://github.com/vlm/asn1c
In I start to make an open source ASN.1 compiler in C from scratchI had to use it at work in a C++ environment and ended up settling on patching a copy of https://github.com/vlm/asn1c
Can't say I'd feel confident putting any of this stuff in a public service. Too complex and prone to bugs.
In A Critique of the Cap'n Proto Schema Language (2019)I've used BER encoded ASN.1 at work quite a bit, and the reason you won't see it much are pretty much:
- HORRIBLE schema format.
- Very few FOSS libraries, most of which are terrible. I used Lev Walkins asn1c[0], which I patched slightly and coupled with some semi-generic code that walks the generated data structures to emit JSON (for debugging purposes).
