Frequently Asked Questions About Online Generators & Cryptographic Tools

Which EverySolve generators use cryptographically secure randomness (CSPRNG)?

All security- and identity-critical generators—Password Generator, Strong Password Generator, Secure Token Generator, and UUID Generator—exclusively use your browser's hardware-seeded Web Crypto API (window.crypto.getRandomValues and crypto.randomUUID) with rejection sampling to eliminate modulo bias. They never use Math.random().

Are generated passwords, API tokens, QR payloads, or barcodes sent to any server?

No. Every tool in the Generators category runs 100% client-side inside your web browser memory. Passwords, passphrases, Hex/Base64URL secret keys, Wi-Fi QR credentials, and product barcode SKUs are never transmitted over the network, logged, or stored.

What is the difference between Password Generator, Strong Password Generator, and Secure Token Generator?

Password Generator creates customizable 4–128 character user passwords with optional look-alike character filtering. Strong Password Generator defaults to 24+ character cryptographic passwords (~155 bits of entropy) or memorable multi-word passphrases. Secure Token Generator outputs raw random bytes encoded as Hex, Base64, Base64URL, or Base62 with optional key prefixes (like sk_live_) for API keys and JWT signing secrets.

How does the Barcode Generator validate EAN-13, UPC-A, Code 128, and Code 39?

Barcode Generator encodes bar/space bit patterns directly into a crisp vector SVG in your browser. For EAN-13 (12 or 13 digits) and UPC-A (11 or 12 digits), it automatically calculates or verifies the GS1 Modulo-10 check digit. For Code 128B, it computes the ISO/IEC 15417 Modulo-103 checksum symbol, and for Code 39 it validates the 43-character industrial alphabet and wraps the code in start/stop (*) delimiters.

Why does Fake Data Generator use @example.com emails and 555-01XX phone numbers?

Under IETF RFC 2606, domains such as example.com, example.org, and example.net are permanently reserved for testing and documentation, and North American 555-0100 through 555-0199 numbers are reserved for fictional use. Using these guarantees that QA test runs never accidentally email or message real individuals, while synthetic test card numbers include valid Modulo-10 Luhn check digits for checkout form testing.

When should I use Lorem Ipsum Generator vs. Text Generator?

Use Lorem Ipsum Generator when you want traditional Latin placeholder text that keeps reviewers focused purely on layout grid and typography without reading the copy. Use Text Generator when you need readable English prose—such as Editorial paragraphs, SaaS & Enterprise Tech copy, or UI Microcopy states—to test realistic English word wrapping, tone, and component overflow.
