Free Password & Security Tools
Security chores pop up mid‑sprint — you need a strong password, a quick hash, or to sanity‑check a token. The password generator, password strength checker, hash generator, and JWT decoder all run client‑side, so you can work safely without sending secrets anywhere.
Security Notice
All security tools process data locally in your browser. No passwords, keys, or sensitive data are transmitted over the internet. For maximum security with critical passwords, consider using offline tools or dedicated password managers.
Essential Security Tools
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
Hash Generator (MD5, SHA-1, SHA-256)
Stop downloading hash calculator software! Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes instantly for file integrity verification, checksums, and data validation. Supports multi-algorithm output, optional salting, hex/Base64 formats, and processes files up to 50MB in your browser. Perfect for developers and security professionals. Free, works offline, unlimited hashing.
Encryption & Decryption Tool
Stop exposing sensitive data! Encrypt and decrypt text instantly using industry-standard AES algorithms. Generate secure keys, protect sensitive data, and learn about cryptography. Supports AES-GCM, AES-CBC, and educational ciphers. Free, works offline, never stored.
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.
File Hash Integrity Checker

Password Security Best Practices
✅ Do These
- • Use unique passwords for every account
- • Create passwords with 12+ characters
- • Include uppercase, lowercase, numbers, and symbols
- • Use a reputable password manager
- • Enable two-factor authentication (2FA)
- • Change passwords immediately if breached
❌ Avoid These
- • Reusing passwords across multiple accounts
- • Using personal information (names, dates)
- • Simple patterns (123456, password, qwerty)
- • Storing passwords in plain text files
- • Sharing passwords via email or messaging
- • Using passwords shorter than 8 characters

Security Tools FAQ
How secure are online password generators?
Our password generator is completely secure because it runs locally in your browser. No passwords are transmitted over the internet or stored on our servers.
Can I trust these tools for sensitive passwords?
Yes, all security tools process data locally. However, for maximum security with critical passwords, consider using offline tools or dedicated password managers.
What makes a password strong?
Strong passwords are long (12+ characters), use mixed character types, avoid dictionary words, and are unique for each account. Our strength checker analyzes all these factors.
How often should I change passwords?
Change passwords immediately if there's a breach, every 90 days for high-security accounts, or annually for regular accounts. Focus on using unique, strong passwords.
Are these tools better than password managers?
These tools complement password managers. Use our generators for one-time password creation, but use a dedicated password manager for storing and managing passwords long-term.
Can I use these tools offline?
Yes, once loaded, all security tools work completely offline. This ensures maximum security since no data can be transmitted even if you wanted to.
