Generate passwords, hashes, checksums, and QR codes privately.
13 tools in this category
Security-related utilities include password generation and strength checks, common hash helpers, file checksums, and QR code create/decode tools. Sensitive operations use browser APIs (such as Web Crypto) when available so values can be produced locally.
These tools are helpers - not a substitute for a password manager, security audit, or professional advice. Never reuse passwords across important accounts.
Open a security utility below - generate, hash, or encode with privacy in mind.
No. Generation is local. Clear the page when finished on shared screens, and store secrets in a password manager.
No. MD5 is not appropriate for password storage. Use modern password hashing in applications; MD5 here is for non-security checksums only.
