This method using CryptoJs library.

1. Install CryptoJs in tour project

    npm install crypto-js
   

2. Create function for encrypt

    // import CryptoJS from 'crypto-js'
   
    export const simpleEncrypt = (textWillEncrypt, strKey) => {
        // textWillEncrypt is something will encrypted
        // strKey is string key for connect encrypt and decrypt
   
        const textEcrypt = CryptoJS.AES.encrypt(textWillEncrypt, strKey).toString()
        return textEcrypt
    }
   

3. Create function for decrypt

    // import CryptoJS from 'crypto-js'
   
    export function simpleDecrypt(textWillDecrypt, strKey) {
        // textWillDecrypt is something will decrypted
        // strKey is string key for connect encrypt and decrypt (must same with function encrypt
   
        const bytes = CryptoJS.AES.decrypt(textWillDecrypt, strKey)
        const originalDecryptText = bytes.toString(CryptoJS.enc.Utf8)
        return originalDecryptText
    }
