雜七雜八的小筆記!

用Java將文字轉成符合Linux下OpenLDAP的slappasswd指令的MD5與SHA編碼!

import java.security.*;
import sun.misc.*;

public class md5
{
    public static void main(String args[]) throws NoSuchAlgorithmException
    {
    MessageDigest md = MessageDigest.getInstance("MD5");
    //MessageDigest md = MessageDigest.getInstance("SHA-1");
    
    String pw = "1234";
    md.update(pw.getBytes());
    byte[] digest = md.digest();
    String base64str = new BASE64Encoder().encodeBuffer(digest);
    System.out.println("MD5 = " + base64str);

    }
}
