Online Security and Privacy Tools for Passwords, Websites and Data Protection
CyberTools gives you practical security and privacy utilities for everyday checks: strong password generation, password strength testing, hashing, SSL inspection, website security auditing, browser privacy testing and security-related developer tasks.
Use these tools when you need a quick technical check without installing a full security suite. They are built for website owners, developers, system administrators, students, researchers and anyone who wants clearer security signals before taking the next step.
Generate Strong Passwords and Test Password Strength
Strong credentials reduce the risk of account takeover and automated guessing. Use the Password Generator to create random passwords, then test existing credentials with the Password Strength Test before using them in important accounts.
Developers can also use the Random Secret Key Generator to create high-entropy values for API keys, JWT secrets, app keys and other sensitive configuration values where predictable text should be avoided.
Hashing tools help convert text into repeatable digest values for checksums, compatibility testing, data workflows and development tasks.
Generate MD5 hash values for legacy checksums, testing and compatibility workflows.
MD5 GeneratorCreate SHA-family hashes for integrity checks, data comparison and development tasks.
SHA GeneratorCreate bcrypt hashes for password-oriented development and authentication testing.
Bcrypt GeneratorWork with several hashing algorithms from one browser-based utility.
Hash GeneratorCheck Security Headers, WAF Protection and SSL Certificates
Website security depends on more than HTTPS alone. HTTP response headers, TLS certificates, browser security policies and reputation signals all affect how browsers and users interact with a website.
Use the Security Headers Auditor to inspect browser-facing security headers, or run the Security Headers & WAF Auditor for a broader review that includes WAF indicators and configuration signals.
You can also inspect certificate details with the SSL Checker and review website safety signals with the Safe Browsing Checker.
Inspect CSP, HSTS, X-Frame-Options and other browser-facing security controls.
Security Headers AuditorRun a broader website security review and identify possible web application firewall protection.
Security Headers & WAF AuditorInspect SSL certificate details and TLS-related information for a hostname.
SSL CheckerCheck whether a website shows known browsing-safety or malware-related warnings.
Safe Browsing CheckerCreate CSP Headers and Security.txt Files
Security configuration often starts with clear policies. The CSP Header Generator helps create Content Security Policy directives that define which resources a website is allowed to load.
Website owners can use the Security.txt Generator to create a standardized disclosure file that tells security researchers where and how vulnerabilities should be reported.
Encryption, Secure Keys and Developer Security Utilities
Encryption protects information by making it unreadable without the right key. The AES-256 Encryption / Decryption Tool tool lets you work with AES-based text encryption and decryption directly from the browser.
CyberTools also includes developer-focused utilities for identifiers, SSH configuration and code protection.
Open the UUIDv4 Generator, SSH Config Generator or JavaScript Obfuscator when those tasks are part of your development workflow.
Check Browser Fingerprinting, WebRTC Leaks and DNS Privacy
Modern browsers expose technical characteristics such as screen details, rendering behavior, capabilities and network-related signals. Combined together, these details can contribute to browser fingerprinting.
Use the Browser Fingerprint Audit to examine fingerprint-related signals, the DNS Leak Tester to investigate DNS resolution behavior and the WebRTC Leak Test to check whether WebRTC may expose IP-related information.
Choose the Right Security Tool for the Job
Decide whether you are checking an account, a website, a browser, a domain or a developer secret.
Use the smallest tool that answers your question, such as a password test, SSL check, DNS leak test or header audit.
Treat the output as technical guidance. Security decisions often need context from your website, server, browser and risk level.
Common Questions About Online Security and Privacy Tools
Are these tools enough for a full security audit?
No. They are useful for focused checks, quick diagnostics and learning, but they do not replace a professional penetration test, code review or full infrastructure audit.
Can I use the password generator for real accounts?
Yes, you can generate strong random passwords and store them in a trusted password manager. Do not reuse passwords across important accounts.
What is the difference between hashing and encryption?
Hashing creates a one-way digest for comparison or integrity checks. Encryption is designed to be reversible with the correct key.
Why should I check security headers?
Security headers help browsers enforce safer behavior, such as limiting framing, controlling resource loading and improving HTTPS handling.
What can a browser privacy test show?
It can show visible browser and network signals such as fingerprinting characteristics, DNS behavior or WebRTC exposure. Results can vary by browser, VPN and network setup.
