Generate cryptographically random passwords with full control over length and character sets. Every password is generated locally using your browser's Web Crypto API — nothing is ever transmitted.
Yes — generated using the Web Crypto API's cryptographically secure random number generator, not Math.random().
No. Generation happens entirely in your browser and nothing is transmitted or stored.
Generate random UUID v4 identifiers instantly, one or in bulk (up to 100 at once). Copy individually or all at once. Perfect for database keys, API testing, and unique identifiers in code. 100% client-side using crypto.randomUUID().
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files instantly. Perfect for verifying file integrity, checksums, and debugging. All hashing happens in your browser using the Web Crypto API — nothing is uploaded.
Comprehensive token tool to decode, verify, and generate JWT (JSON Web Tokens) and PASETO (Platform-Agnostic SEcurity TOkens) instantly. View header, payload, and signature sections with syntax-highlighted JSON. Generate new tokens with custom payloads. Perfect for developers debugging authentication tokens, API tokens, and bearer tokens. Features instant real-time decoding as you type, support for both JWT and PASETO token formats, token generation with custom algorithms (HS256, HS384, HS512), three-part visualization showing header/version, payload, and signature/footer separately, color-coded JSON syntax highlighting for easy reading, one-click copy to clipboard for each section, and complete client-side processing for maximum security. All token processing happens entirely in your browser - tokens are never transmitted to any server, ensuring complete privacy and security. Supports all standard JWT formats and PASETO v2/v4. Ideal for debugging authentication flows, inspecting API tokens, generating test tokens, understanding token structure, validating token claims, and learning about modern authentication. No installation or registration required.
