Variable-time functions are explicitly marked as such.\n- Leverage what is possible today with const generics on `stable` rust.\n- Support `const fn` as much as possible with the goal of being able to compute\n  values at compile-time.\n- Optional heap-allocated `Boxed*` types gated under an `alloc` feature.\n\n## Security Notes\n\nThis crate has been [audited by NCC Group] with no significant\nfindings. We would like to thank [Entropy] for funding the audit.\n\nAll functions contained in the crate are designed to execute in constant\ntime unless explicitly specified otherwise (via a `*_vartime` name suffix).\n\nThis library is not suitable for use on processors with a variable-time\nmultiplication operation (e.g. short circuit on multiply-by-zero /\nmultiply-by-one, such as certain 32-bit PowerPC CPUs and some non-ARM\nmicrocontrollers).\n\n## License\n\nLicensed under either of:\n\n- [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0)\n- [MIT license](http://opensource.org/licenses/MIT)\n\nat your option.\n\n### Contribution\n\nUnless you explicitly state otherwise, any contribution intentionally submitted\nfor inclusion in the work by you, as defined in the Apache-2.0 license, shall be\ndual licensed as above, without any additional terms or conditions.\n\n[//]: # (badges)\n\n[crate-image]: https://img.shields.io/crates/v/crypto-bigint?logo=rust\n[crate-link]: https://crates.io/crates/crypto-bigint\n[docs-image]: https://docs.rs/crypto-bigint/badge.svg\n[docs-link]: https://docs.rs/crypto-bigint/\n[build-image]: https://github.com/RustCrypto/crypto-bigint/actions/workflows/crypto-bigint.yml/badge.svg?branch=master\n[build-link]: https://github.com/RustCrypto/crypto-bigint/actions/workflows/crypto-bigint.yml?query=branch:master\n[license-image]: https://img.shields.io/badge/license-Apache2.0/MIT-blue.svg\n[rustc-image]: https://img.shields.io/badge/rustc-1.85+-blue.svg\n[chat-image]: https://img.shields.io/badge/zulip-join_chat-blue.svg\n[chat-link]: https://rustcrypto.zulipchat.com/#narrow/stream/300602-crypto-bigint\n\n[//]: # (links)\n\n[RustCrypto]: https://github.com/rustcrypto\n[audited by NCC Group]: https://www.nccgroup.com/us/research-blog/public-report-entropyrust-cryptography-review/\n[Entropy]: https://entropy.xyz/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FRustCrypto%2Fcrypto-bigint","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FRustCrypto%2Fcrypto-bigint","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FRustCrypto%2Fcrypto-bigint/lists"}
