-///
-/// Calculate a hash in one go.
-///
-/// ```
-/// use openssl::crypto::hash::{hash, MessageDigest};
-///
-/// let data = b"\x42\xF4\x97\xE0";
-/// let spec = b"\x7c\x43\x0f\x17\x8a\xef\xdf\x14\x87\xfe\xe7\x14\x4e\x96\x41\xe2";
-/// let res = hash(MessageDigest::md5(), data).unwrap();
-/// assert_eq!(res, spec);
-/// ```
-///
-/// Use the `Write` trait to supply the input in chunks.
-///
-/// ```
-/// use openssl::crypto::hash::{Hasher, MessageDigest};
-///
-/// let data = [b"\x42\xF4", b"\x97\xE0"];

-///
-/// Don't actually use MD5 and SHA-1 hashes, they're not secure anymore.
-///
-/// Don't ever hash passwords, use `crypto::pkcs5` or bcrypt/scrypt instead.
