We now have a method `add_tweak` on the `SecretKey` and `PublicKey`. We can add similar methods that consumes self and return the tweaked key for the `KeyPair` and `XOnlyPublicKey` types. The justification for doing so is that a local variable that calls `tweak_add_assign` changes in meaning but the identifier remains the same, this leads to cumbersome renaming of the local variable. The tweaking done to the `KeyPair` is actually done via the xonly public key not the public key. To reflect this call the method `add_xonly_tweak`, this is similar to how it is named in secp `secp256k1_keypair_xonly_tweak_add`. |

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.
