For testing purposes, you can use the following 32-byte secret key. Text copy the code a154eb4c759711bc2538a7cc021e9e9f17dd8aa63151c62ca28a82a4a404203d create an aes encryption function start by creating a function to handle encryption and decryption of data using symmetric cryptography . Node.js crypto node.js includes a cryptography module called crypto . Crypto provides several useful methods, such as createcipheriv() and createdecipheriv() , to specify the type of block cipher algorithm to use.

Gcm block cipher the advanced encryption singapore mobile number list standard , or aes, data protection technique uses algorithms to perform encryption. Aes supports many modes of operation . In this solution, you will use gcm (galois/counter mode) . symmetric cryptography is preferred for its speed and strength. Code create a new function named aes with the following code: javascript copy the code const crypto = require("crypto") const algorithm = { block_cipher: "aes-256-gcm", auth_tag_byte_size: 16, iv_byte_size: 12, } exports.



Create an encrypted-gather function next, create the function that will perform the sensitive operations. You will configure it as a voice webhook of the incoming phone number in a later step. This function allows the digits entered by the caller to be encrypted upon receipt and sent in this state to the final "destination" function. Code create a new function named encrypted-gather with the following code: javascript copy the code const axios = require('axios') const aes = require(runtime.
