how to store data on firebase from android?

Question

This is how I store data on firebase.But can anyone suggest, how to encrypt password and save it?

   save.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String user,pass;
            user =name.getText().toString();
            pass=password.getText().toString();

            Firebase usersRef = Ref.child("user");
          //  usersRef.child("username").setValue(user);
          //  usersRef.child("password").setValue(pass);

            Map<String,String> mUser = new HashMap<String, String>();
            mUser.put("username",user);
            mUser.put("password",pass);
            usersRef.push().setValue(mUser);

        }
    });

You can use any encryption method to encrypt your password but one of the best practice for encrypting password is to use MessageDigest.

You can use below method to convert your password with MD5 and encrypt it.

public static String convertPassMd5(String pass) {
        String password = null;
        MessageDigest mdEnc;
        try {
            mdEnc = MessageDigest.getInstance("MD5");
            mdEnc.update(pass.getBytes(), 0, pass.length());
            pass = new BigInteger(1, mdEnc.digest()).toString(16);
            while (pass.length() < 32) {
                pass = "0" + pass;
            }
            password = pass;
        } catch (NoSuchAlgorithmException e1) {
            e1.printStackTrace();
        }
        return password;
    }

thank you sir .then while user logs in,how to decript the password ? – Dhanraj Naik Aug 04 '15 at 05:01
MessageDigest encryption is not reversible. You can not get the original string. Every time you need to encrypt it and have to match with the encrypted string. As password should be confidential. – Dhrumil Shah - dhuma1981 Aug 04 '15 at 05:22

Try adding a sample code along with a little explanation or documentation of the same. That makes a better answer. – Darshan Miskin May 18 '21 at 04:58
