Add Target onion_decode

**Custom Mutator Development** - Integrate secp256k1 as a library within the custommutator directory for cryptographic operations - Implement a custom mutator that performs the following workflow: 1. Decrypt the onion...

We currently don't use automated code formatters, leading to inconsistent formatting and manual formatting effort. Should we establish one for each language? Or establish one just for the bitcoinfuzz framework...

Make differential fuzzing between secp256k1 libraries

6

I think the main libraries we should have here are those written in different programming languages. For example, we will not add Rust-secp256k1, an FFI of secp256k1 from Bitcoin Core....

Core Lightning parses an even TLV type 100 (wrong_funding) in shutdown messages that other Lightning implementations don't recognize. Since even TLV types are required to be understood by all implementations,...

Add Target onion_legacy_decode

10

I'll develop the fuzzing targets in two phases: starting with the legacy onion format, followed by the modern TLV-based onion format. ### Legacy Onion Format **Custom Mutator Development** - Integrate...

Add docker to our CI

We need to test if the Docker image is being built correctly, without errors.

Add target for Onion packet decoding

1

It may be interesting to write a fuzz target in the future that would decode one layer of the hop data and compare results between implementations... _Originally posted by @morehouse...

Add Target for BOLT12 Invoice Request Decode

This PR adds a new fuzzing target for BOLT12 offer decoding to our differential fuzzing. It implements the `deserialize_invoice_request` target and adds support for it in the `clightning` and `ldk`...
