Question

The operation cannot be completed because the property 'HmacSHA256' is undefined

I'm attempting to encrypt an ID for use as parameters in Vue.js using Crypto-JS, but I keep encountering the error message: Cannot read property 'HmacSHA256' of undefined. I ran into the same issue when trying ASE and MD5. What am I doing wrong? Below is my code:

//in main.js
import CryptoJS from 'crypto-js'
Vue.use(CryptoJS)

//in my component
goToEvent (singleEvent) {
  const id = this.CryptoJS.HmacSHA256(singleEvent.id, 'mySecretKey').toString(this.CryptoJS.enc.Hex)
  this.$store.commit('SET_SELECTED_EVENT', singleEvent)
  this.$router.push(`/admin/events/event/${id}`)
}

javascript vue.js cryptojs

Answer №1

To integrate encryption in your component, insert import CryptoJS from 'crypto-js' into the file. Then, apply CryptoJS.HmacSHA256(...) as shown below:

encryptData (data) {
  const encryptedData = CryptoJS.HmacSHA256(data, 'secretKey').toString(CryptoJS.enc.Hex)
  this.$store.dispatch('saveEncryptedData', encryptedData)
}

Note: Do not use Vue.use(CryptoJS) as 'crypto-js' is not a valid Vue plugin.

Alternatively, you can utilize a different Vue plugin called Vue CryptoJS. In your single file component, access the CryptoJS instance using any of the following methods:

Vue.CryptoJS
this.CryptoJS
this.$CryptoJS

Thank you so much for your assistance! I realized that I needed to convert my value to a JSON string and make some adjustments to ensure it was URL-friendly. Here is the final solution that worked for me:

import CryptoJS from 'crypto-js'

const key = 'mysecrete'

// Encryption
export function Encrypt(text) {
    const b64 = CryptoJS.AES.encrypt(JSON.stringify(text), key).toString()
    const e64 = CryptoJS.enc.Base64.parse(b64)
    return e64.toString(CryptoJS.enc.Hex)
}

// Decryption
export function Decrypt(text) {
    const reb64 = CryptoJS.enc.Hex.parse(text)
    const bytes = reb64.toString(CryptoJS.enc.Base64)
    const decrypt = CryptoJS.AES.decrypt(bytes, key)
    return decrypt.toString(CryptoJS.enc.Utf8)
}

Now I can easily import this solution into any component.
