我可以将Model的属性另存为哈希吗？

import hashlib

class Model:
    def __init__(self, attribute):
        self.attribute = attribute

    def get_hash(self):
        return hashlib.sha256(self.attribute.encode()).hexdigest()

model = Model("example_attribute")
hashed_attribute = model.get_hash()
print(hashed_attribute)

const crypto = require('crypto');

class Model {
    constructor(attribute) {
        this.attribute = attribute;
    }

    getHash() {
        return crypto.createHash('sha256').update(this.attribute).digest('hex');
    }
}

const model = new Model('example_attribute');
const hashedAttribute = model.getHash();
console.log(hashedAttribute);

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class Model {
    private String attribute;

    public Model(String attribute) {
        this.attribute = attribute;
    }

    public String getHash() {
        try {
            MessageDigest md = MessageDigest.getInstance("SHA-256");
            byte[] hash = md.digest(attribute.getBytes());
            StringBuilder sb = new StringBuilder();
            for (byte b : hash) {
                sb.append(String.format("%02x", b));
            }
            return sb.toString();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
            return null;
        }
    }
}

public class Main {
    public static void main(String[] args) {
        Model model = new Model("example_attribute");
        String hashedAttribute = model.getHash();
        System.out.println(hashedAttribute);
    }
}
