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.
