Tobin C. Harding 2a1c9ab4b8 Remove rand-std feature from unstable 
Currently the "unstable" feature (used to guard bench mark code) turns
on the "recovery" and "rand-std" features. The "rand-std" feature is not
needed since it is unused, as can be seen by the following bench runs:

Before applying this patch:

...
test benches::bench_sign_ecdsa               ... bench:      35,454 ns/iter (+/- 1,376)
test benches::bench_verify_ecdsa             ... bench:      44,578 ns/iter (+/- 1,619)
test benches::generate                       ... bench:      26,800 ns/iter (+/- 2,352)
test ecdh::benches::bench_ecdh               ... bench:      51,195 ns/iter (+/- 1,400)
test ecdsa::recovery::benches::bench_recover ... bench:      50,174 ns/iter (+/- 1,572)
test key::benches::bench_pk_ordering         ... bench:       5,748 ns/iter (+/- 492)

test result: ok. 0 passed; 0 failed; 76 ignored; 6 measured; 0 filtered out; finished in 14.52s

After removing "rand-std" feature:
...
test benches::bench_sign_ecdsa               ... bench:      35,510 ns/iter (+/- 1,504)
test benches::bench_verify_ecdsa             ... bench:      42,483 ns/iter (+/- 5,628)
test benches::generate                       ... bench:      26,573 ns/iter (+/- 1,333)
test ecdh::benches::bench_ecdh               ... bench:      50,846 ns/iter (+/- 3,982)
test ecdsa::recovery::benches::bench_recover ... bench:      50,908 ns/iter (+/- 2,775)
test key::benches::bench_pk_ordering         ... bench:       6,002 ns/iter (+/- 463)

test result: ok. 0 passed; 0 failed; 60 ignored; 6 measured; 0 filtered out; finished in 6.52s

Build Status

Full documentation

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 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.

Githooks

To assist devs in catching errors before running CI we provide some githooks. If you do not already have locally configured githooks you can use the ones in this repository by running, in the root directory of the repository:

git config --local core.hooksPath githooks/

Alternatively add symlinks in your .git/hooks directory to any of the githooks we provide.

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.
