How to Use Ephemeral Private Paste

Sharing confidential credentials, API keys, database connection strings, and private passwords across team communication channels like Slack, Teams, or email poses severe security risks. Chat transcripts are permanently recorded, searchable, and susceptible to data breaches. Ephemeral Private Paste solves this problem through zero-knowledge end-to-end encryption and "Burn After Reading" technology. Using the native Web Crypto API, your secret is encrypted in your browser with AES-256-GCM. The decryption key lives strictly in the URL hash fragment (#key=...), ensuring that our servers only ever receive unreadable ciphertext.
