Since we bumped the MSRV we have `to_le_bytes` available now, use it instead of `mem::transmute`. Remove code comment suggesting to do exactly this and clear clippy warning. While we are at it, use `cast` instead of `as`. |

rust-secp256k1
rust-secp256k1 is a wrapper around libsecp256k1,
a C library by Pieter Wuille for producing ECDSA signatures using the SECG curve
secp256k1. This library
- exposes type-safe Rust bindings for all
libsecp256k1functions - 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.
