1//! An implementation of the RIPEMD-160 cryptographic hash.
2//!
3//! RIPEMD (RIPE Message Digest) is a family of cryptographic hash functions
4//! developed in 1992 (the original RIPEMD) and 1996 (other variants). There are
5//! five functions in the family: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256,
6//! and RIPEMD-320, of which RIPEMD-160 is the most common.

9//! ```
10//! use cryptoxide::{ripemd160::Ripemd160, digest::Digest};
11//!
12//! let mut digest = [0u8; 20];
13//! let mut context = Ripemd160::new();
14//!
15//! context.input(b"hello world");
16//! context.result(&mut digest);
17//! ```
