Security Tools Collection
A free, growing library of 43+ security tools you can use directly in your browser - password and passphrase generators, hashing and encryption utilities, classic and modern ciphers, and a newer AI Security category covering API key generation, red-team payload testing, guardrail configuration, NIST-aligned model cards, PII redaction, and prompt injection testing. Everything runs client-side, with no signup and nothing stored.
About This Collection
This page brings together every tool from the Strong Random Password Generator project in one place, so you don't need to remember individual URLs. It spans five categories: password and passphrase generation, encryption and hashing, general security utilities, everyday utilities like QR and UUID generators, and a newer AI Security set built for teams working with large language models.
What's in each category
- Password: Random, memorable, and emoji password generators plus a password strength checker.
- Encryption: Modern hashing (SHA-256, SHA-512, SHA-1, MD5, HMAC) and encoding (Base64, Base58, UUEncode) alongside classic ciphers (Caesar, Vigenere, Atbash, ROT13, Affine, A1Z26, RSA) kept for education and puzzles.
- Security: 2FA setup, CAPTCHA generation, recovery codes, security questions, hashcat rules, and Diffie-Hellman key exchange simulation.
- Utilities: QR codes, UUIDs, promo codes, secure tokens, and random codes for everyday use.
- AI Security: API key generation, red-team payload creation, entropy-based seed generation, guardrail configuration, NIST model cards, password entropy calculation, PII redaction, and prompt injection test generation.
Every tool listed here is free, requires no registration, and - with the exception of a few utilities that are explicitly informational or educational - runs its core logic locally in your browser.
Why Use These Tools
Complete Anonymity
No registration, no login, no personal information required for any tool in the collection.
Mostly Client-Side
Most tools process everything in your browser. Nothing you generate or paste in is uploaded to a server.
One Place, 43+ Tools
Passwords, hashing, encryption, ciphers, and AI security utilities together instead of scattered across separate sites.
Content Security Policy
Strict CSP headers help prevent malicious scripts and protect against XSS attacks and data injection.
Built for AI Security Work
Red-team payloads, guardrail configs, NIST model cards, and prompt injection tests aimed at teams securing LLM deployments.
Full Responsiveness
Works on desktop, tablet, and mobile with an interface optimized for each screen size.

Frequently Asked Questions
1. Are these security tools really free to use?
Yes. Every tool in this collection is completely free, with no signup, subscription, or hidden premium tier. All 43+ tools are supported by the same team behind the Strong Random Password Generator.
2. Is my data safe when I use these tools?
Almost all tools in this collection process your input entirely client-side, in your browser, so nothing is uploaded to a server. Cryptographic operations use the Web Crypto API where applicable. Always check an individual tool's own notes if you're handling especially sensitive data.
3. What's the difference between the encryption and cipher tools?
Modern cryptographic tools like AES, RSA, SHA-256, and HMAC are designed for real-world security and are safe to rely on. Classical ciphers such as Caesar, Vigenere, Atbash, and ROT13 are included for education, puzzles, and historical interest only, and should never be used to protect sensitive information.
4. What are the new AI security tools for?
The AI Security category covers tools built for teams working with large language models: API key generation, red-team payload creation for adversarial testing, guardrail configuration, NIST-aligned model cards, PII redaction, and prompt injection test generation. They're meant to support security testing and documentation of systems you have permission to test - not for use against systems you don't.
5. How do I find a specific tool in this collection?
Use the search box to filter tools by name or description, or use the category buttons to browse by Password, Encryption, Security, Utilities, or AI Security.
