Missing AES-GCM Authentication Tag Validation and Improper Deprecation Handling

**Summary:** In Node.js' crypto module, the `createDecipheriv` states that "the `authTagLength` option defaults to 16 bytes and must be set to a different value if a different length is used." …

const {
    createCipheriv,
    createDecipheriv
} = require('crypto');

const key = 'key0123456789key';
const nonce = '123456789012';

var algo = 'aes-128-gcm';
const cipher = createCipheriv(algo, key, nonce);
const plaintext = 'This is some plaintext';

const ciphertext = cipher.update(plaintext, …
