Example to Convert any Input Value in MD5 in React Native

MD5 Encoding

This is an Example to Convert any Input Value in MD5 in React Native. We will use the function md5() to convert our Input Text into MD5. You need this useful example while making your login and registration screen because we do not store the user’s password as it is; we first encode the password and then store it in the database.

Encoding password in md5 is the basic encoding and is not recommended for high-security platforms instead of that use SHA256 encoding for the password. You can also encode the password with both using MD5 and SHA256 after each other which will make the decoding of the password nearly impossible.

MD5 stands for ‘Message-Digest algorithm 5’. The MD5 algorithm is used as a cryptographic hash function or a file fingerprint. It is non-reversible and very safe for password security.

How to Encode any Text to MD5?


To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react native command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use md5() we have to install md5 package.

To install this open the terminal and jump into your project using

cd ProjectName

Run the following command

npm install md5 --save

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named md5. –save is optional, it is just to update the md5 dependency in your package.json file.

Code to Encode any Text to MD5

Now Open App.js in any code editor and replace the code with the following code


// Example to Convert any Input Value in MD5 in React Native
// https://aboutreact.com/md5-in-react-native/

// import React in our code
import React, {useState} from 'react';

// import all the components we are going to use
import {
} from 'react-native';

//import md5 to use md5()
import md5 from 'md5';

const App = () => {
  const [inputText, setInputText] = useState('');
  const [text, setText] = useState('');

  const convertMD5 = () => {
    let encodedVal = md5(inputText);

  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
        <Text style={styles.titleStyle}>
          Example to Convert any Input Value in MD5 in React Native
        <Text style={styles.textStyle}>{text}</Text>
        <Text style={styles.textStyle}>
          Please insert any value to convert in md5
            (inputText) => setInputText(inputText)
          placeholder="Enter Any Value"
          <Text style={styles.buttonTextStyle}>
            Conver to MD5
export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    justifyContent: 'center',
    padding: 10,
  titleStyle: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  textStyle: {
    textAlign: 'center',
    margin: 10,
  textInputStyle: {
    flexDirection: 'row',
    height: 40,
    marginTop: 20,
    marginLeft: 35,
    marginRight: 35,
    margin: 10,
  buttonStyle: {
    backgroundColor: '#51D8C7',
    borderWidth: 0,
    color: '#FFFFFF',
    borderColor: '#51D8C7',
    height: 40,
    alignItems: 'center',
    borderRadius: 5,
    marginLeft: 35,
    marginRight: 35,
    marginTop: 30,
  buttonTextStyle: {
    color: '#FFFFFF',
    paddingVertical: 10,
    fontSize: 16,

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios

  1. DO NOT USE AN MD5 FOR STORING PASSWORDS. Make sure you read up on the topic before taking and storing users’ passwords. SHA-256 or BCrypt are safer alternatives.
