Oncepad

About

Oncepad enables the secure sharing of files, passwords, API keys, or environment variables via a single-use link that self-destructs after access. All data is encrypted directly in your browser using AES-256-GCM encryption with a unique seven-word passphrase. The server stores only encrypted data temporarily in memory, never writing it to disk. Since the link contains no encryption key, it can be safely shared over email, Slack, or support tickets, while the passphrase is sent separately. No user account, cookies, analytics, or installation is required. Any unopened secrets or files automatically expire within 24 hours.
