//! SHA, or Secure Hash Algorithms, are a family of cryptographic hashing algorithms published by
//! the National Institute of Standards and Technology (NIST). Hash algorithms such as those in
//! the SHA family are used to map data of an arbitrary size to a fixed-size string of bytes.
//! As cryptographic hashing algorithms, these mappings have the property of being irreversible.
//! This property makes hash algorithms like these excellent for uses such as verifying the
//! contents of a file- if you know the hash you expect beforehand, then you can verify that the
//! data you have is correct if it hashes to the same value.
//!
//! # Examples
//!
//! When dealing with data that becomes available in chunks, such as while buffering data from IO,
//! you can create a hasher that you can repeatedly update to add bytes to.
//!
//! ```rust
//! use openssl::sha;
//!
//! let mut hasher = sha::Sha256::new();
//!
//! hasher.update(b&quot;Hello, &quot;);
//! hasher.update(b&quot;world&quot;);
//!
//! let hash = hasher.finish();
//! println!(&quot;Hashed \&quot;Hello, world\&quot; to {}&quot;, hex::encode(hash));
//! ```
//!
//! On the other hand, if you already have access to all of the data you would like to hash, you
//! may prefer to use the slightly simpler method of simply calling the hash function corresponding
//! to the algorithm you want to use.
//!
//! ```rust
//! use openssl::sha::sha256;
//!
//! let hash = sha256(b&quot;your data or message&quot;);
//! println!(&quot;Hash = {}&quot;, hex::encode(hash));
//! ```
