使用php和java进行密码加密

$password = "user_password";
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

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

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