Generators
Generate cryptographically secure random identifiers, hash values, and design tokens. Create UUID v4s for databases and APIs, generate MD5/SHA hashes for verification, and build custom Tailwind CSS theme configurations.

Frequently Asked Questions
Are generated UUIDs truly unique?
UUID v4 uses 122 bits of cryptographic randomness, giving 5.3 × 10³⁶ possible values. The probability of collision is astronomically small — effectively impossible in practice.
What hash algorithms are supported?
The Hash Generator supports MD5, SHA-1, SHA-256, and SHA-512. For production security use cases, prefer SHA-256 or SHA-512 — MD5 and SHA-1 are considered cryptographically weak.
Is the Tailwind Theme Generator compatible with Tailwind v3 and v4?
The generator outputs a standard color scale that is compatible with Tailwind CSS v3 (tailwind.config.js extend block). Tailwind v4 uses CSS variables directly — the color values can be adapted accordingly.
Does the UUID generator require any server calls?
No. UUIDs are generated using the browser's native crypto.randomUUID() API (with crypto.getRandomValues() as fallback). No network request is made.
