よくある質問

Which .env syntax is supported?

Standard dotenv: KEY=value, optional quotes (single or double), # comments, export prefix, and \n escapes inside double-quoted strings.

What triggers secret masking?

A regex against the key name: TOKEN, KEY, SECRET, PASSWORD, PASSWD, API, AUTH - case-insensitive. Never share masked output as a substitute for actual secret handling.

Does it handle multi-line values?

Multi-line values inside double-quoted strings using \n are supported. Raw multi-line values across lines aren't part of the dotenv spec.

Is my file uploaded?

No. Everything runs in your browser.
