Security Tools

Free online security tools to generate strong passwords, encrypt text, and calculate cryptographic hashes. Our secure password generator creates high-entropy passwords with customisable length and character sets, using the Web Crypto API for true randomness. Encrypt sensitive messages with AES-GCM encryption directly in your browser—no data leaves your device, ensuring complete privacy. Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes instantly to verify file integrity and check data fingerprints. All security utilities run 100% client-side, meaning your passwords, encrypted text, and sensitive data are never transmitted to any server. These are essential tools for developers verifying API signatures, users creating secure credentials, or anyone needing safe, private cryptographic operations without third-party services.
