JSON to Java
Generate Java DTOs and review validation-oriented API models.
Password
Create strong temporary passwords for non-production use
Choose length and character classes (upper, lower, digit, symbol) to generate copyable passwords for QA accounts, staging logins, and one-off shares.
How to use it safely
Values are generated locally via Web Crypto and are not transmitted, but still avoid pasting them into chat logs or issue trackers — drop them straight into a password manager.
For real user passwords, hash the value on the server with bcrypt or argon2 and force a user-driven rotation. Do not store the raw string produced here.
