### rust-secp256k1
|
|
|
|
`rust-secp256k1` is a wrapper around [libsecp256k1](https://github.com/bitcoin-core/secp256k1),
|
|
a C library by Pieter Wuille for producing ECDSA signatures using the SECG curve
|
|
`secp256k1`. This library
|
|
* exposes type-safe Rust bindings for all `libsecp256k1` functions
|
|
* implements key generation
|
|
* implements deterministic nonce generation via RFC6979
|
|
* implements many unit tests, adding to those already present in `libsecp256k1`
|
|
* makes no allocations (except in unit tests) for efficiency and use in freestanding implementations
|
|
|
|
### Contributing
|
|
|
|
Contributions to this library are welcome. A few guidelines:
|
|
|
|
* Any breaking changes must have an accompanied entry in CHANGELOG.md
|
|
* No new dependencies, please.
|
|
* No crypto should be implemented in Rust, with the possible exception of hash functions. Cryptographic contributions should be directed upstream to libsecp256k1.
|
|
* This library should always compile with any combination of features on **Rust 1.41.1**.

## Fuzzing
|
|
|
|
If you want to fuzz this library, or any library which depends on it, you will
|
|
probably want to disable the actual cryptography, since fuzzers are unable to
|
|
forge signatures and therefore won't test many interesting codepaths. To instead
|
|
use a trivially-broken but fuzzer-accessible signature scheme, compile with
|
|
`--cfg=fuzzing` in your `RUSTFLAGS` variable.
|
|
|
|
Note that `cargo hfuzz` sets this config flag automatically.
