Why use ToolsVito security tools?
Secrets never leave your device
Encryption, hashing and signing all run locally with Web Crypto — your keys and plaintext are never uploaded, logged or stored.
Standards-based
Real algorithms — bcrypt, AES-GCM, HMAC-SHA, HS/RS/ES JWT — not toy implementations. Verify as well as generate.

No accounts, no limits. Works on mobile, tablet or desktop in any modern browser.
