Frequently Asked Questions
What is CSPRNG and why is it important?
CSPRNG (Cryptographically Secure Pseudo-Random Number Generator) uses your operating system's entropy pool to generate truly unpredictable values. Unlike standard random functions (like Math.random()), CSPRNG meets rigorous cryptographic security standards, making it suitable for generating passwords, API keys, encryption keys, and other security-critical data. Our generators are safe for production use and security-sensitive applications.
Is Generate-Random.org really free? Are there any limits?
Yes, completely free forever with no hidden costs or premium tiers. You can generate up to 10,000 items per request through our web interface and API. There's no registration required, no credit card needed, and no usage limits. Our mission is to provide high-quality random data generation tools accessible to everyone, from individual developers to enterprise teams.
How secure are the generated passwords and keys?
Extremely secure. All passwords, API keys, encryption keys, and security tokens are generated using CSPRNG, which provides cryptographic-grade randomness suitable for production environments. Generated data is never logged, stored, or transmitted to third parties. Each generation request produces completely unique, unpredictable values. However, always use HTTPS when accessing our site and never share generated credentials insecurely.
Can I use the API for commercial projects?
Absolutely! Our free REST API is available for personal, commercial, and enterprise use without restrictions. Integrate it into your CI/CD pipelines, testing frameworks, or production applications. No authentication required for basic usage. The API supports all 50+ generators with consistent JSON responses, making integration straightforward. Check our API documentation for implementation details and code examples.
What's the difference between UUID v4 and UUID v7?
UUID v4 generates completely random identifiers with excellent uniqueness but no inherent ordering. UUID v7 includes a timestamp prefix, making them naturally sortable by creation time - perfect for database primary keys where chronological ordering improves query performance. UUID v7 is the newest standard (2022) and recommended for most modern applications, while v4 remains ideal when temporal information shouldn't be exposed.
Do you store or track the data I generate?
No, never. Generated data (passwords, keys, tokens, etc.) is created on-the-fly and immediately discarded after being sent to you. We don't log, store, or analyze any generated values. Standard web server logs may record access patterns for security and performance monitoring, but never the actual random data generated. Your privacy is our top priority - what you generate stays completely private.
Can I generate lottery numbers for all major lotteries?
Yes! We support 20+ major lotteries worldwide including Powerball, Mega Millions, EuroMillions, UK Lotto, and many more. Each generator respects the specific rules of that lottery (number ranges, bonus ball systems, etc.). While we provide truly random number selection, remember that lottery outcomes are independent - no generator can predict or influence actual lottery results.
How do I integrate the generators into my automated tests?
Use our REST API with simple HTTP GET requests. Example: curl "https://generate-random.org/api/v1/generate/passwords?length=16&count=5" returns JSON with 5 random passwords. Works with any HTTP client in any language (Python requests, JavaScript fetch, Java HttpClient, etc.). Perfect for seeding test databases with fake person data, generating test API keys, or creating mock UUIDs. See our full API documentation with code examples in multiple languages.
