Does Qwertygen store my code or paste content on a database?

No. The entire paste payload is encrypted in your browser using AES-256-GCM and stored within the URL hash fragment (#paste=...). We have zero servers or databases storing your pastes.

Which programming languages and syntaxes are supported?

Supported syntaxes include Plain Text, JavaScript, TypeScript, Python, JSON, HTML, CSS, Markdown, SQL, Bash, and YAML.

Can I password-protect my paste?

Yes. You can optionally enforce a custom passphrase. PBKDF2 key derivation with 100,000 rounds ensures high resistance against brute-force attacks.
