Unlike other pastebins, SecureBin detects secrets before sharing

Most pastebin tools just encrypt and share. SecureBin goes further by scanning your content for sensitive data before you create the link. API keys, database credentials, private keys, and passwords are detected instantly in your browser. You see exactly what you are about to share, and you can choose to mask sensitive values before creating the encrypted link.

This detection runs entirely in your browser using pattern matching. Nothing is sent to our servers. The analysis and the encryption both happen locally. That is what zero knowledge means: we physically cannot see what you paste, what we detect, or what you share.
