Password Generator
Stop using weak passwords! Generate cryptographically strong passwords instantly with custom length, character sets, and exclusion rules. Create secure passwords for accounts, API keys, and encryption. Bulk generation available. Free, works offline, never stored.
Password Strength Checker
Analyze password strength and security with comprehensive checks for common vulnerabilities, patterns, and entropy calculation. Get detailed improvement suggestions.
Password Policy Generator
Generate comprehensive password policies with compliance standards, validation rules, and implementation guides for different organizational needs
File Hash Integrity Checker
Generate, verify, and compare file hashes for integrity checking using multiple cryptographic algorithms.
JWT Generator
Stop manually crafting JWT tokens for API testing! Generate secure JSON Web Tokens (JWT) instantly with HMAC, RSA, or ECDSA signing. Add custom claims, set expiration, configure audiences and issuers. Perfect for testing authentication flows and OAuth implementations. Free, works offline, no server uploads.
Encryption Key Generator
Generate cryptographically secure encryption keys for JWT secrets, API keys, database encryption, and environment variables. Supports multiple formats and key sizes.
Hash & Integrity Tool
Unified hash generator with text/file hashing, multi-algorithm support, integrity verification, and batch processing — all client-side.
