END-TO-END ENCRYPTED • AES-256-GCM
01.

Zero Knowledge

We don't store your decryption keys. Data is encrypted client-side before upload.

02.

Ephemeral

Automated garbage collection ensures data is wiped from RAM and disk immediately.

03.

Global

Ultra-low latency delivery via our globally distributed edge network.

How It Works

1

Encrypt Locally

Your browser generates a random AES-256 key and encrypts your file or text before it ever leaves your device.

2

Upload Securely

Only the encrypted data is uploaded. The decryption key is embedded in the URL fragment and never sent to our server.

3

Share & Destruct

Share the link. The recipient's browser decrypts the data locally. After expiry, the encrypted blob is permanently destroyed.

API & CLI Guide

Upload files directly from your terminal on Linux, macOS, or Windows.

# Upload a file
curl -X POST -F "file=@/path/to/file.pdf" \
     -F "expiry=24h" \
     https://upload-temp.stream4tech.app/upload

# Upload text
curl -X POST -F "text=Your secret message" \
     -F "expiry=1h" \
     https://upload-temp.stream4tech.app/upload

# Upload with password
curl -X POST -F "file=@document.pdf" \
     -F "expiry=24h" -F "password=mySecret" \
     https://upload-temp.stream4tech.app/upload

# Download a file
curl -O -J "https://upload-temp.stream4tech.app/api/d/<short_id>"

# Download with wget
wget --content-disposition "https://upload-temp.stream4tech.app/api/d/<short_id>"
Note: CLI uploads skip client-side encryption. For zero-knowledge security, use the web interface or pre-encrypt your files with openssl or gpg before uploading via CLI.
