Share API Keys Safely with Developers
API keys and access tokens are as powerful as passwords, yet they're often pasted straight into tickets, chat, and email. cinderpaste lets you send API keys safely as encrypted, burn-after-reading links so they never sit in plaintext.
The risk of keys in plaintext
A leaked key can mean unauthorized charges, data exposure, or a full account takeover. Once it's in a chat log or an email thread, it's effectively permanent and searchable — exactly what an attacker wants to find.
Sending a key to a developer
Paste the key, set a short expiry, and enable burn after reading. Hand the link to the developer directly. Their browser decrypts it locally, and the moment they open it, the paste is destroyed — no copy remains on the server.
Rotate after sharing
For high-value credentials, rotate the key after it's been delivered and received. Combined with a one-time encrypted link, this keeps the window of exposure as small as possible.
