Share Simply POST a multipart form file. You can upload as many as you want and can use any field name you like: curl -F'file=@/path/to/file' -F'file2=@/path/to/file' $url All files are encrypted when stored on the server. I do not store the keys to the file. If you lose the key (the hash part of the download URL) you will not be able to download your data.
