+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## 0.10.5 (2022-09-16)
+### Added
+- Feature-gated OID support ([#405])
+
+[#405]: https://github.com/RustCrypto/hashes/pull/405

+## 0.10.4 (2022-09-02)
+### Fixed
+- MSRV issue which was not resolved by v0.10.3 ([#401])
+
+[#401]: https://github.com/RustCrypto/hashes/pull/401
+
+## 0.10.3 (2022-09-02)
+### Fixed
+- MSRV issue caused by publishing v0.10.2 using a buggy Nightly toolchain ([#399])
+
+[#399]: https://github.com/RustCrypto/hashes/pull/399
+
+## 0.10.2 (2022-08-30)
+### Changed
+- Ignore `asm` feature on unsupported targets ([#388])
+
+[#388]: https://github.com/RustCrypto/hashes/pull/388

+## 0.10.1 (2022-02-17)
+### Fixed
+- Minimal versions build ([#363])

+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and

+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,

+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the

+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+
+Pure Rust implementation of the [SHA-1 hash function][1].
+
+[Documentation][docs-link]
+
+## 🚨 Warning: Cryptographically Broken 🚨
+
+The SHA-1 hash function should be considered cryptographically broken and
+unsuitable for further use in any security critical capacity, as it is
+[practically vulnerable to chosen-prefix collisions][2].
+
+We provide this crate for legacy interoperability purposes only.
+
+## Minimum Supported Rust Version
+
+Rust **1.41** or higher.
+
+Minimum supported Rust version can be changed in the future, but it will be
+done with a minor version bump.
+
+## SemVer Policy
+
+- All on-by-default features of this library are covered by SemVer
+- MSRV is considered exempt from SemVer as noted above

+//! Pure Rust implementation of the [SHA-1][1] cryptographic hash algorithm
+//! with optional hardware-specific optimizations.
+//!
+//! # 🚨 Warning: Cryptographically Broken! 🚨
+//!
+//! The SHA-1 hash function should be considered cryptographically broken and
+//! unsuitable for further use in any security critical capacity, as it is
+//! [practically vulnerable to chosen-prefix collisions][2].
+//!
+//! We provide this crate for legacy interoperability purposes only.
+//!
+//! # Usage
+//!
+//! ```rust
+//! use hex_literal::hex;
+//! use sha1::{Sha1, Digest};
+//!
+//! // create a Sha1 object
+//! let mut hasher = Sha1::new();
+//!
+//! // process input message
+//! hasher.update(b"hello world");
+//!
+//! // acquire hash digest in the form of GenericArray,
+//! // which in this case is equivalent to [u8; 20]
+//! let result = hasher.finalize();
+//! assert_eq!(result[..], hex!("2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"));
+//! ```
+//!
+//! Also see [RustCrypto/hashes][3] readme.
+//!
+//! # Note for users of `sha1 v0.6`
+//!
+//! This crate has been transferred to the RustCrypto organization and uses
+//! implementation previously published as the `sha-1` crate. The previous
+//! zero dependencies version is now published as the [`sha1_smoll`] crate.
