create a md5 hash from a string in rust

To create a MD5 hash from a string in Rust, you can use the md5 crate which provides an implementation of the MD5 message digest algorithm.

First, add the following line to your Cargo.toml file to include the md5 crate as a dependency:

[dependencies]
md5 = "0.8.1"
29 chars
3 lines

Then, in your Rust code, you can use the Md5 struct from the md5 crate to create a new MD5 hash instance and update it with the string data. Finally, you can retrieve the hash value as a byte array using the finalize method.

Here's an example:

main.rs
use md5::{Digest, Md5};

fn main() {
    let input_string = "hello world";
    
    let mut hasher = Md5::new();
    hasher.update(input_string.as_bytes());
    
    let hash_result = hasher.finalize();
    
    println!("{:x}", hash_result);
}
245 chars
13 lines

This will output the MD5 hash of the "hello world" string in hexadecimal format.
