Every developer has faced the problem: how to share an API key, database credential, .env file, or SSH key with a teammate without exposing it in Slack, email, or a GitHub commit. Traditional methods like copy-pasting into chat channels create permanent, searchable exposure.

VaultBridge solves this with encrypted file sharing that requires no login, no account, and automatically destroys the shared content after download. Your secrets stay secret.

Upload your .env file, API key document, or config to VaultBridge. It is encrypted with AES-256-GCM in your browser before upload. You receive a 6-digit access code that you share with your teammate via a separate channel.

Your teammate enters the code, the file is decrypted in their browser, and the vault auto-destructs. The server never sees the plaintext content, and no record of the transfer persists. This is zero-knowledge file sharing optimized for developer workflows.

For small secrets like individual API keys or short config snippets, use VaultBridge's Universal Encrypted Clipboard. Paste your secret, and it's immediately encrypted and available on any device with the access code. The data lives only in RAM — never on disk.

This is faster and more secure than any file sharing tool for quick developer secret exchange. It supports real-time sync via encrypted WebSockets with zero persistence.
