If the default doesn't match your system, set `OPENSSL_DIR` via one of these methods: + +**vcpkg (any platform)** +```powershell +# Windows +$triplet = "x64-windows" # or x64-windows-static, arm64-windows, etc. +$env:OPENSSL_DIR = "$env:VCPKG_ROOT\installed\$triplet" + +# Linux/macOS +export OPENSSL_DIR="$VCPKG_ROOT/installed/x64-linux" # or x64-osx +``` + +**Homebrew (macOS)** +```bash +export OPENSSL_DIR="$(brew --prefix openssl@3)" +``` + +**System OpenSSL (Linux)** +```bash +export OPENSSL_DIR="/usr" # headers in /usr/include/openssl, libs in /usr/lib +# or +export OPENSSL_DIR="/usr/local" # if built from source +``` + +**Vendored (no system OpenSSL required)** +```bash +cargo check -p cose_sign1_crypto_openssl --features openssl/vendored +``` +This compiles OpenSSL from source and requires Perl + a C compiler. + +### Runtime DLL discovery (Windows) + +On Windows with dynamically-linked OpenSSL, tests need the DLLs on `PATH`: +```powershell +$env:PATH = "$env:OPENSSL_DIR\bin;$env:PATH" +``` +The `collect-coverage.ps1` script handles this automatically. + +## Orchestrator Plan Configuration + +When creating Copilot orchestrator plans for native code: + +### Environment +- **Plan-level `env`**: Set `OPENSSL_DIR` for crates that depend on OpenSSL. **Discover the path** rather than hardcoding it — use `$VCPKG_ROOT\installed\` or the appropriate system path: + ```json + "env": { "OPENSSL_DIR": "\\installed\\x64-windows" } + ``` + Replace `` with the actual vcpkg installation directory on the target machine (e.g., from `$env:VCPKG_ROOT` or `vcpkg env`). + +### Work Specs — `allowedFolders` +- **Every agent work spec** that compiles Rust code linking OpenSSL MUST include `allowedFolders` pointing to the directory that contains the OpenSSL installation, so the agent sandbox can access headers and libraries: + ```json + "work": { + "type": "agent", + "model": "claude-sonnet-4.5", + "allowedFolders": [""], + "instructions": "..." + } + ``` +- Discover `` from `$env:VCPKG_ROOT`, or from the parent of whichever directory `OPENSSL_DIR` resolves to (e.g., if `OPENSSL_DIR` is `/usr/local`, allow `/usr/local`). +- This applies to ALL jobs in plans that build `cose_sign1_crypto_openssl`, `cose_sign1_certificates`, `cose_sign1_certificates_local`, or any crate that transitively depends on OpenSSL. +- Without `allowedFolders`, the agent cannot read OpenSSL headers and compilation will fail. + +### Postchecks +- **Per-crate postchecks**: Use `cargo check -p ` (NOT `--exclude` with `-p`) +- **Workspace postchecks**: Use `cargo check --workspace --exclude cose_openssl --exclude cose_openssl_ffi` +- **Test postchecks**: Use `cargo test --workspace --exclude cose_openssl --exclude cose_openssl_ffi --no-fail-fast` +- `cose_openssl` (partner crate) requires separate OpenSSL setup — always exclude from workspace checks. diff --git a/.github/instructions/native-c-cpp.instructions.md

allocated via `CString::into_raw()`. +- Caller frees with `cose_string_free(s)` which calls `CString::from_raw()`. +- **NEVER** return `&str` or `String` across FFI — always `CString`. +- Input

It is designed +to be minimal with only `cbor_primitives` as a dependency, making it suitable +for constrained environments. + +**Important**: This library is generic over `CborProvider` and does not include +a default CBOR implementation. Callers must provide their own `CborProvider` +implementation (such as `cbor_primitives_everparse::EverParseCborProvider`) to all +encoding and decoding functions. + +## Features + +- **CoseKey trait** - Abstraction for signing/verification keys +- **CoseHeaderMap** - Protected and unprotected header handling +- **CoseSign1Message** - Parse and verify COSE_Sign1 messages +- **CoseSign1Builder** - Fluent API for creating messages +- **Sig_structure** - RFC 9052 compliant signature structure construction +- **Streaming support** - Handle large payloads without full memory load via `SizedRead` + +## Design Philosophy + +This crate intentionally has minimal dependencies: + +- Only `cbor_primitives` as a dependency (no `thiserror`, no `once_cell`) +- Manual `std::error::Error` implementations +- Uses `std::sync::OnceLock` (stable since Rust 1.70) instead of `once_cell` + +This keeps the crate dependency-free for customers who need minimal footprint. + +## Usage + +```rust +use cbor_primitives::CborProvider; +use cbor_primitives_everparse::EverParseCborProvider; +use cosesign1_primitives::{ + CoseSign1Builder, CoseSign1Message, CoseHeaderMap, CoseKey, + algorithms, +}; + +// Callers must provide a concrete CborProvider implementation +let provider = EverParseCborProvider; + +// Create protected headers +let mut protected = CoseHeaderMap::new(); +protected.set_alg(algorithms::ES256); + +// Sign a message +let message_bytes = CoseSign1Builder::new() + .protected(protected) + .sign(&provider, &signing_key, b"payload")?; + +// Parse and verify +let message = CoseSign1Message::parse(provider, &message_bytes)?; +let valid = message.verify(&verification_key, None)?; +``` + +## Key Components + +### CoseKey Trait + +The `CoseKey` trait abstracts over different key types.

CBOR byte strings require the length to be encoded +in the header **before** the actual content bytes: + +```text +bstr header: 0x5a 0x00 0x10 0x00 0x00 (indicates 1MB of bytes follow) +bstr content: <1MB of actual payload bytes> +``` + +This creates a problem for streaming: you need to know the total length before +you can start writing the CBOR encoding. + +### Why Rust's `Read` Doesn't Include Length + +Rust's standard `Read` trait intentionally doesn't include a `len()` method because: + +- **Many streams have unknown length** - network sockets, pipes, stdin, compressed data +- **`Seek::stream_len()` mutates** - it requires `&mut self` since it seeks to end and back +- **Length is context-dependent** - a `File` knows its length via `metadata()`, but wrapping + it in `BufReader` loses that information + +### The Solution: `SizedRead` Trait + +We provide the `SizedRead` trait that combines `Read` with a required `len()` method: + +```rust +pub trait SizedRead: Read { + /// Returns the total number of bytes in this stream. + fn len(&self) -> Result; +} +``` + +### Built-in Implementations + +`SizedRead` is automatically implemented for common types: + +| Type | How Length is Determined | +|------|--------------------------| +| `std::fs::File` | `metadata().len()` | +| `std::io::Cursor` | `get_ref().as_ref().len()` | +| `&[u8]` | slice `.len()` | + +### Wrapping Unknown Streams + +For streams where you know the length externally (e.g., HTTP Content-Length header): + +```rust +use cose_sign1_primitives::{SizedReader, sized_from_reader}; + +// HTTP response with known Content-Length +let body = response.into_reader(); +let content_length = response.content_length().unwrap(); +let payload = sized_from_reader(body, content_length); +// or equivalently: +let payload = SizedReader::new(body, content_length); +``` + +### Streaming Hash Functions + +Once you have a `SizedRead`, use the streaming functions: + +```rust +use sha2::{Sha256, Digest}; +use cose_sign1_primitives::{hash_sig_structure_streaming, open_sized_file}; + +// Open a file (File implements SizedRead via metadata) +let payload = open_sized_file("large_payload.bin")?; + +// Hash the Sig_structure in 64KB chunks - never loads full payload into memory +let hasher = hash_sig_structure_streaming( + &cbor_provider, + Sha256::new(), + protected_header_bytes, + None, // external_aad + payload, +)?; + +let hash: [u8; 32] = hasher.finalize().into(); +// Now sign the hash with your key +``` + +### Convenience Functions + +| Function | Purpose | +|----------|---------| +| `open_sized_file(path)` | Open a file as `SizedRead` | +| `sized_from_reader(r, len)` | Wrap any `Read` with known length | +| `sized_from_bytes(bytes)` | Wrap `Vec` / `&[u8]` as `Cursor` | +| `hash_sig_structure_streaming(...)` | Hash Sig_structure in chunks (64KB default) | +| `hash_sig_structure_streaming_chunked(...)` | Same with custom chunk size | +| `stream_sig_structure(...)` | Write complete Sig_structure to any `Write` | + +### IntoSizedRead Trait + +For ergonomic conversions, use the `IntoSizedRead` trait: + +```rust +use cose_sign1_primitives::IntoSizedRead; +use std::fs::File; + +// File already implements SizedRead, so this is a no-op wrapper +let payload = File::open("payload.bin")?.into_sized()?; + +// Vec converts to Cursor> +let payload = my_bytes.into_sized()?;

Handles returned by this library must be freed using the corresponding `*_free` function: +//! - `cose_sign1_message_free` for message handles +//! - `cose_sign1_error_free` for error handles +//! - `cose_sign1_string_free` for string pointers +//! - `cose_headermap_free` for header map handles +//! - `cose_key_free` for key handles +//! +//! Pointers to internal data (e.g., from `cose_sign1_message_protected_bytes`) are valid +//! only as long as the parent handle is valid. +//! +//! ## Thread Safety +//! +//! All handles are thread-safe and can be used from multiple threads. However, handles +//! are not internally synchronized, so concurrent mutation requires external synchronization. +//! +//! ## Example (C) +//! +//! ```c +//! #include "cose_sign1_primitives_ffi.h" +//! +//! int verify_message(const uint8_t* data, size_t len, CoseKeyHandle* key) { +//! CoseSign1MessageHandle* msg = NULL; +//! CoseSign1ErrorHandle* err = NULL; +//! bool verified = false; +//! +//! // Parse the message +//! int rc = cose_sign1_message_parse(data, len, &msg, &err); +//! if (rc != 0) { +//! char* msg = cose_sign1_error_message(err); +//! printf("Parse error: %s\n", msg); +//! cose_sign1_string_free(msg); +//! cose_sign1_error_free(err); +//! return rc; +//! } +//! +//! // Verify (no external AAD) +//! rc = cose_sign1_message_verify(msg, key, NULL, 0, &verified, &err); +//! if (rc != 0) { +//! char* msg = cose_sign1_error_message(err); +//! printf("Verify error: %s\n", msg); +//! cose_sign1_string_free(msg); +//! cose_sign1_error_free(err); +//! cose_sign1_message_free(msg); +//! return rc; +//! } +//! +//! printf("Signature valid: %s\n", verified ? "yes" : "no"); +//! cose_sign1_message_free(msg); +//! return 0; +//! } +//! ``` + +pub mod error; +pub mod message; +pub mod provider; +pub mod types; + +use std::panic::{catch_unwind, AssertUnwindSafe};
