use crypto::digest::Digest;

fn main(){

    let mut hasher = Md5::new();

    let text = String::from("123456");

    hasher.input_str(&text);
    
    println!("{} => {}",text,hasher.result_str())
    
}

• sha1

use crypto::sha1::Sha1;
use crypto::digest::Digest;

fn main(){

    let mut hasher = Sha1::new();

    let text = String::from("123456");

    hasher.input_str(&text);
    
    println!("{} => {}",text,hasher.result_str())
    
}

• sha256

use crypto::sha2::Sha256;
use crypto::digest::Digest;

fn main(){

    let mut hasher = Sha256::new();

    let text = String::from("123456");

    hasher.input_str(&text);
    
    println!("{} => {}",text,hasher.result_str())
    
}

• sha512

Sha256替换成Sha512即可
