Chromium Network Errors

Provides Chromium network errors found in net_error_list.h as custom error classes that can be conveniently used in Node.js, Electron apps and browsers.

The errors correspond to the error codes that are provided in Electron's did-fail-load events of the WebContents class and the webview tag.

Features

• No dependencies.
• 100% test coverage.
• ES6 build with import and export, and a CommonJS build. Your bundler can use the ES6 modules if it supports the "module" or "jsnext:main" directives in the package.json.
• Daily cron-triggered checks for updates on net_error_list.h on Travis CI to always get the most up-to-date list of errors.

Installation

npm install chromium-net-errors --save

import * as chromiumNetErrors from 'chromium-net-errors';
// or
const chromiumNetErrors = require('chromium-net-errors');

Example Use in Electron

import { app, BrowserWindow } from 'electron';
import * as chromiumNetErrors from 'chromium-net-errors';

app.on('ready', () => {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
  });

  win.webContents.on('did-fail-load', (event) => {
    try {
      const Err = chromiumNetErrors.getErrorByCode(event.errorCode);
      throw new Err();
    } catch (err) {
      if (err instanceof chromiumNetErrors.NameNotResolvedError) {
        console.error(`The name '${event.validatedURL}' could not be resolved:\n  ${err.message}`);
      } else {
        console.error(`Something went wrong while loading ${event.validatedURL}`);
      }
    }
  });

  win.loadURL('http://blablanotexist.com');
});

Usage

import * as chromiumNetErrors from 'chromium-net-errors';

Create New Errors

const err = new chromiumNetErrors.ConnectionTimedOutError();

console.log(err instanceof Error);
// true
console.log(err instanceof chromiumNetErrors.ChromiumNetError);
// true
console.log(err instanceof chromiumNetErrors.ConnectionTimedOutError);
// true

function thrower() {
  throw new chromiumNetErrors.ConnectionTimedOutError();
}

try {
  thrower();
} catch (err) {
  console.log(err instanceof Error);
  // true
  console.log(err instanceof chromiumNetErrors.ChromiumNetError);
  // true
  console.log(err instanceof chromiumNetErrors.ConnectionTimedOutError);
  // true
}

Get Error by errorCode

Get the class of an error by its errorCode.

const Err = chromiumNetErrors.getErrorByCode(-201);
const err = new Err();

console.log(err instanceof chromiumNetErrors.CertDateInvalidError);
// true

console.log(err.isCertificateError());
// true

console.log(err.type); 
// 'certificate'

console.log(err.message);
// The server responded with a certificate that, by our clock, appears to
// either not yet be valid or to have expired. This could mean:
// 
// 1. An attacker is presenting an old certificate for which they have
// managed to obtain the private key.
// 
// 2. The server is misconfigured and is not presenting a valid cert.
// 
// 3. Our clock is wrong.

Get Error by errorDescription

Get the class of an error by its errorDescription.

const Err = chromiumNetErrors.getErrorByDescription('CERT_DATE_INVALID');
const err = new Err();

console.log(err instanceof chromiumNetErrors.CertDateInvalidError);
// true

console.log(err.isCertificateError());
// true

console.log(err.type); 
// 'certificate'

console.log(err.message);
// The server responded with a certificate that, by our clock, appears to
// either not yet be valid or to have expired. This could mean:
// 
// 1. An attacker is presenting an old certificate for which they have
// managed to obtain the private key.
// 
// 2. The server is misconfigured and is not presenting a valid cert.
// 
// 3. Our clock is wrong.

Get All Errors

WrongVersionOnEarlyDataError

TLS 1.3 early data was offered, but the server responded with TLS 1.2 or earlier. This is an internal error code to account for a backwards-compatibility issue with early data and TLS 1.2. It will be received before any data is returned from the socket. The request should be retried with early data disabled.

See https://tools.ietf.org/html/rfc8446#appendix-D.3 for details.

Tls13DowngradeDetectedError

TLS 1.3 was enabled, but a lower version was negotiated and the server returned a value indicating it supported TLS 1.3. This is part of a security check in TLS 1.3, but it may also indicate the user is behind a buggy TLS-terminating proxy which implemented TLS 1.2 incorrectly. (See https://crbug.com/boringssl/226.)

const err = new Err();

CertCommonNameInvalidError

The server responded with a certificate whose common name did not match the host name. This could mean:

1. An attacker has redirected our traffic to their server and is presenting a certificate for which they know the private key.

2. The server is misconfigured and responding with the wrong cert.

3. The user is on a wireless network and is being redirected to the network's login page.

4. The OS has used a DNS search suffix and the server doesn't have a certificate for the abbreviated name in the address bar.

• Name: CertCommonNameInvalidError

const Err = chromiumNetErrors.getErrorByDescription('CERT_COMMON_NAME_INVALID');
const err = new Err();

CertDateInvalidError

The server responded with a certificate that, by our clock, appears to either not yet be valid or to have expired. This could mean:

1. An attacker is presenting an old certificate for which they have managed to obtain the private key.

2. The server is misconfigured and is not presenting a valid cert.

3. Our clock is wrong.

• Name: CertDateInvalidError
• Code: -201

const Err = chromiumNetErrors.getErrorByDescription('CERT_DATE_INVALID');
const err = new Err();

CertAuthorityInvalidError

The server responded with a certificate that is signed by an authority we don't trust. The could mean:

1. An attacker has substituted the real certificate for a cert that contains their public key and is signed by their cousin.

2. The server operator has a legitimate certificate from a CA we don't know about, but should trust.

3. The server is presenting a self-signed certificate, providing no defense against active attackers (but foiling passive attackers).

• Name: CertAuthorityInvalidError
• Code: -202
• Description: CERT_AUTHORITY_INVALID
• Type: certificate

const err = new chromiumNetErrors.CertAuthorityInvalidError();
// or
const Err = chromiumNetErrors.getErrorByCode(-202);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_AUTHORITY_INVALID');
const err = new Err();

CertContainsErrorsError

The server responded with a certificate that contains errors. This error is not recoverable.

MSDN describes this error as follows: "The SSL certificate contains errors." NOTE: It's unclear how this differs from ERR_CERT_INVALID. For consistency, use that code instead of this one from now on.

• Name: CertContainsErrorsError
• Code: -203
• Description: CERT_CONTAINS_ERRORS
• Type: certificate

const err = new chromiumNetErrors.CertContainsErrorsError();
// or
const Err = chromiumNetErrors.getErrorByCode(-203);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_CONTAINS_ERRORS');
const err = new Err();

CertNoRevocationMechanismError

The certificate has no mechanism for determining if it is revoked. In effect, this certificate cannot be revoked.

• Name: CertNoRevocationMechanismError
• Code: -204
• Description: CERT_NO_REVOCATION_MECHANISM
• Type: certificate

const err = new chromiumNetErrors.CertNoRevocationMechanismError();
// or
const Err = chromiumNetErrors.getErrorByCode(-204);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_NO_REVOCATION_MECHANISM');
const err = new Err();

CertUnableToCheckRevocationError

Revocation information for the security certificate for this site is not available. This could mean:

1. An attacker has compromised the private key in the certificate and is blocking our attempt to find out that the cert was revoked.

2. The certificate is unrevoked, but the revocation server is busy or unavailable.

• Name: CertUnableToCheckRevocationError
• Code: -205
• Description: CERT_UNABLE_TO_CHECK_REVOCATION
• Type: certificate

const err = new chromiumNetErrors.CertUnableToCheckRevocationError();
// or
const Err = chromiumNetErrors.getErrorByCode(-205);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_UNABLE_TO_CHECK_REVOCATION');
const err = new Err();

CertRevokedError

The server responded with a certificate has been revoked. We have the capability to ignore this error, but it is probably not the thing to do.

• Name: CertRevokedError
• Code: -206
• Description: CERT_REVOKED
• Type: certificate

const err = new chromiumNetErrors.CertRevokedError();
// or
const Err = chromiumNetErrors.getErrorByCode(-206);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_REVOKED');
const err = new Err();

CertInvalidError

The server responded with a certificate that is invalid. This error is not recoverable.

MSDN describes this error as follows: "The SSL certificate is invalid."

• Name: CertInvalidError
• Code: -207
• Description: CERT_INVALID
• Type: certificate

const err = new chromiumNetErrors.CertInvalidError();
// or
const Err = chromiumNetErrors.getErrorByCode(-207);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_INVALID');
const err = new Err();

CertWeakSignatureAlgorithmError

The server responded with a certificate that is signed using a weak signature algorithm.

• Name: CertWeakSignatureAlgorithmError
• Code: -208
• Description: CERT_WEAK_SIGNATURE_ALGORITHM
• Type: certificate

const err = new chromiumNetErrors.CertWeakSignatureAlgorithmError();
// or
const Err = chromiumNetErrors.getErrorByCode(-208);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_WEAK_SIGNATURE_ALGORITHM');
const err = new Err();

CertNonUniqueNameError

The host name specified in the certificate is not unique.

• Name: CertNonUniqueNameError
• Code: -210
• Description: CERT_NON_UNIQUE_NAME
• Type: certificate

const err = new chromiumNetErrors.CertNonUniqueNameError();
// or
const Err = chromiumNetErrors.getErrorByCode(-210);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_NON_UNIQUE_NAME');
const err = new Err();

CertWeakKeyError

The server responded with a certificate that contains a weak key (e.g. a too-small RSA key).

• Name: CertWeakKeyError
• Code: -211
• Description: CERT_WEAK_KEY
• Type: certificate

const err = new chromiumNetErrors.CertWeakKeyError();
// or
const Err = chromiumNetErrors.getErrorByCode(-211);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_WEAK_KEY');
const err = new Err();

CertNameConstraintViolationError

The certificate claimed DNS names that are in violation of name constraints.

• Name: CertNameConstraintViolationError
• Code: -212
• Description: CERT_NAME_CONSTRAINT_VIOLATION
• Type: certificate

const err = new chromiumNetErrors.CertNameConstraintViolationError();
// or
const Err = chromiumNetErrors.getErrorByCode(-212);
const err = new Err();
// or
const Err = chromiumNetErrors.getErrorByDescription('CERT_NAME_CONSTRAINT_VIOLATION');
const err = new Err();

CertValidityTooLongError

The certificate's validity period is too long.

• Name: CertValidityTooLongError
• Code: -213
