Well your only answer is to also write your own asn1 parser

Just learned about Alex Gaynor's Claude-Code-assisted PR to the LLVM project implementing a new compiler optimization - his write-up: alexgaynor.net/2025/jun/20/...

My notes: simonwillison.net/2025/Jun/30/...
llvm: InstCombine: improve optimizations for ceiling division with no overflow—a PR by Alex Gaynor and Claude Code
Alex Gaynor maintains rust-asn1, and recently spotted a missing LLVM compiler optimization while hacking on it, with the assistance of Claude (Alex works for Anthropic). He describes how he confirmed ...

there's still a bit of work to do — but it's happening.

My PhD student filed his first bug report against Erlang/OTP today! github.com/erlang/otp/i...
asn1 application: problem decoding REAL 0 values · Issue #9096 · erlang/otp
Describe the bug The Erlang ASN.1 compiler generates code that crashes when it is invoked to decode REAL 0 values. To Reproduce Use file RealTest.asn1 containing the following ASN.1 encoding: RealT...

This cursed world in which I have to use the `asn1.Unmarshal` is golang package.
Did you know that golang's crypto.sign produces DER encoded signatures, but JWS (JSON Web Signatures) reject DER encoded signatures? I didn't until today

It does this for ES256 but not RS256. I noticed this when changing the algorithm from ES256 --> RS256 broke my unittest

In cryptography, there are some very popular data formats: base64, DER, ASN1, PEM. Go's parsers on *all* these data types are just too relaxed. As in, not only does it permit junk whitespace all over (base64 and PEM) it also permits literal *junk data* in ASN1, if un-bothersome.

Java ist ja schon an sich schlimm. Aber wer ASN.1 erfunden hat kann sich von mir aus echt gehackt legen...

Ich mein, die ed25519 C-Library ist ja schon nichts Schönes. Dokumentation = nicht vorhanden. Aber da muss man sich wenigstens nicht mit über 40 Jahre altem Geraffel herumschlagen.

When I started working on this one here (the prologue to Armen Smut No. 1) I got the flu.
Now with ASN1 itself I got Covid.

But I swear if I catch something again while working on ASN2, the universe is clearly trying to sabotage me 😂

There is a VS Code extension for it that requires Python on the box. Once installed, find a .json or .jsons or .proto or .xsd or .asn1 or .avsc file in the file explorer, right click and find "Convert To".
