MessageDigest in Rust

Question

I'm not really that strong in cryptography, so I'm striving to understand what this Java code exactly does:

MessageDigest md = MessageDigest.getInstance("SHA-256");
md.update("some string".getBytes("UTF-8"));
byte[] digest = md.digest();

and convert it to Rust.

So how can I do the same thing in Rust, what traits should I use? Is it http://doc.rust-lang.org/rustc/util/sha2/struct.Sha256.html or something else?

are you found a solution about this issue? I want to do the same thing.@Incerteza — Dolphin, Dec 24 '21 at 17:54

rustc::util::sha2::Sha256 is part of the Rust compiler and is not meant for external use. You should use the rust-crypto crate instead. Its sha2 module implements SHA-256.

how do I create a MessageDigest and get "digest" part of it? – Incerteza Nov 22 '14 at 12:22
