Security tools for everyday use. Generate cryptographically secure passwords with customizable length, character sets, and pronounceable options. Test password strength against common attack patterns (dictionary words, character entropy, brute-force estimation) and get suggestions for improvement. For hash generation and JWT decoding, see the Developer Tools category — LaiUse keeps related tools grouped by function rather than mixing security, encoding, and crypto utilities together. All security tools process data locally — your test passwords never leave your device.
Get embed code for the JWT Decoder — let visitors inspect JWT tokens on your site.
Get embed code for the Password Generator — strong passwords for your users on your site.
Get embed code for the Password Strength Tester — entropy/crack-time for your sign-up form.
Test password strength with entropy calculation and crack time estimates. All processing done locally.
