Up1234me: A client-side encrypted file host based on Up1. Basically, the random private key after # in the URL is used for encryption and decryption in the browser (javascript), this key is never sent to the server. See Up1 for details.

Changes compared to Up1

• it's for generic files, not mainly for pictures
• http basic authentication for upload and admin (mostly for single upload user)
• simpler html & js, I didn't get it :-), server golang only
• unencrypted metadata: description, expiry, viewercandelete
• a very basic administrator interface (list, delete)
• single server binary thanks to go-bindata
• upload:
  • multiple-file uploads, which are zipped in the browser
  • secret url is copied to clipboard after upload
  • upload expiry, runs every day
  • limit total storage size
• download:
  • files can be automatically downloaded if link opened
  • only images+svg are previewed in browser (automatic download is disabled for them)
  • uploads can be deleted by viewer if uploader has allowed it

Getting started

• download an executable of up1234me or build yourselves (below), then do in the same folder:
• create config.js based on config.js.example
• create http basic auth file in the server folder: htpasswd -c server.htpasswd <username>
• create server.conf based on server.conf.example and create the writable folder "storage_path"
• run (as webapp user) for example ./up1234me-linux-amd64
• use a reverse proxy for https
• go to /upload and drag'n'drop, click or paste files to add to upload list. Click "Upload!" to upload.

Build

go-bindata

This is used to make a single executable file also containing the static files under client/ (html, js, css etc.).

go get -u github.com/go-bindata/go-bindata/v3/... 
go-bindata client/...        # put static files into bindata.go

For debugging use

go-bindata -debug client/... # development: use normal files via bindata.go

cross-build

GOOS=linux GOARCH=amd64 go build -o up1234me-linux-amd64

or build and run

go build && ./up1234me
