Cryptographic Failures in Adonisjs with Cockroachdb

AdonisJS applications using CockroachDB can be exposed to cryptographic failures when sensitive operations rely on weak or misconfigured primitives, and when data is handled inconsistently between the application layer and the distributed SQL layer. A cryptographic failure occurs when data that should remain confidential or tamper-proof—such as authentication tokens, API keys, or personal information—is stored, transmitted, or processed without adequate protection.

In this stack, the risk is amplified by the distributed nature of CockroachDB, where data may be replicated across nodes and regions. If an AdonisJS app encrypts data before writing to CockroachDB, but fails to manage keys securely or uses deterministic encryption, an attacker who gains read access to the database may still recover sensitive values. Conversely, if the application relies on CockroachDB’s built-in TLS for transport security but does not enforce encryption at rest for sensitive columns, data can be exposed through unauthorized direct access to storage or backups.

Another common pattern involves hashing or signing operations performed in JavaScript within AdonisJS. Developers might use Node.js’s crypto module incorrectly—such as using weak algorithms like MD5 or SHA1 for password storage, or failing to use a salt with sufficient entropy. When such hashes are stored in CockroachDB columns, they become low-effort targets for offline brute-force attacks. Real-world examples include CVE-2021-21342-like scenarios where weak hashing leads to credential compromise, or CVE-2022-24999-like exposures where insufficient randomness results in predictable tokens.

Additionally, improper key management within AdonisJS services—such as hardcoding encryption keys in environment files checked into version control—can allow attackers who compromise the application repository or logs to decrypt data stored in CockroachDB. Since CockroachDB supports full-text search and secondary indexes, unencrypted sensitive fields can be queried and exported even when TLS is enforced. The OWASP API Security Top 10 category Cryptographic Failures applies directly here, as APIs built with AdonisJS often expose endpoints that return sensitive data without verifying that payloads are encrypted in transit and at rest.

To mitigate cryptographic failures in an AdonisJS application backed by CockroachDB, implement defense-in-depth measures that cover data at rest, in transit, and during application-level processing. Below are concrete remediation steps with code examples tailored to this stack.

1. Use Strong Algorithms and Proper Key Management

Ensure that cryptographic operations use modern algorithms. For password storage, prefer bcrypt over legacy hashes. Store encryption keys outside the database and avoid hardcoding them.

// app/Helpers/EncryptionHelper.js
const bcrypt = require('bcrypt')
const crypto = require('crypto')

class EncryptionHelper {
  static async hashPassword(plainPassword) {
    const saltRounds = 12
    return await bcrypt.hash(plainPassword, saltRounds)
  }

  static verifyPassword(plainPassword, hashedPassword) {
    return await bcrypt.compare(plainPassword, hashedPassword)
  }

  static generateSecureToken() {
    return crypto.randomBytes(32).toString('hex')
  }
}

module.exports = EncryptionHelper

2. Encrypt Sensitive Fields Before Inserting into CockroachDB

Use application-level encryption for fields such as email addresses or API keys before they are persisted. This ensures that even if an attacker gains read access to CockroachDB, the data remains protected.

// start/hooks/encrypt-sensitive-data.js
const crypto = require('crypto')
const EncryptionHelper = use('App/Helpers/EncryptionHelper')

const ALGORITHM = 'aes-256-gcm'

async function encryptData(data, key) {
  const iv = crypto.randomBytes(12)
  const cipher = crypto.createCipher(ALGORITHM, key)
  cipher.setAAD(Buffer.from('adonisjs-cockroach'))
  let encrypted = cipher.update(data, 'utf8', 'hex')
  encrypted += cipher.final('hex')
  return {
    iv: iv.toString('hex'),
    encryptedData: encrypted,
    authTag: cipher.getAuthTag().toString('hex')
  }
}

// Usage in a controller
async store ({ request, response }) {
  const apiKey = request.input('api_key')
  const key = process.env.ENCRYPTION_KEY // Must be 32 bytes
  const encrypted = await encryptData(apiKey, key)

  await Database.table('users').insert({
    user_id: request.user().id,
    encrypted_api_key: JSON.stringify(encrypted)
  })

  return response.status(201).send({ stored: 'encrypted' })
}

3. Enforce TLS and Validate Certificates

Ensure that all connections to CockroachDB use TLS with strict certificate validation. In AdonisJS, configure the database connection to require TLS and provide a trusted CA certificate.

// config/database.js
module.exports = {
  connection: {
    client: 'pg',
    connection: {
      host: process.env.COCKRACKER_HOST,
      port: process.env.COCKRACKER_PORT,
      database: process.env.COCKRACKER_DB,
      user: process.env.COCKRACKER_USER,
      password: process.env.COCKRACKER_PASSWORD,
      ssl: {
        rejectUnauthorized: true,
        ca: fs.readFileSync('/path/to/ca.pem').toString()
      }
    }
  }
}

4. Audit and Monitor Access Patterns

Use CockroachDB’s built-in audit capabilities alongside AdonisJS logging to detect unusual access to sensitive tables. While this does not replace encryption, it helps identify potential breaches early.

By combining these practices, you reduce the likelihood of cryptographic failures and align the AdonisJS + CockroachDB stack with secure development best practices.
