Data Dead Drop

Simple, secure file sharing. Data self-destroys after access.

Usage

Visit https://datadeaddrop.com to upload files, or upload files via the command line. For example using cURL:

curl https://datadeaddrop.com/upload \
  -X POST -H "Accept: application/json" \
  -F "upload[file][email protected]" -F "upload[expiry]=10" -F "upload[uses]=3"

Uploaded data will automatically be deleted after the specified number of minutes or uses. The maximum expiry is 60 minutes, and the maximum number of uses is 5. File size is limited to 1MB.

Data Dead drop will return a unique link generated using the Diceware algorithm method. Use this link to download the file in the browser or via the command line.

curl https://datadeaddrop.com/download/your-secret-key \
  -L -H "Accept: application/json" > "your-file.text"
