# File upload, pastebin, and URL shortening all in one app


File sharing, url shortener and pastebin all in one place with QR code and curl support. Uses stream based cryptography and data processing that can handle gigabytes of data with fixed memory and cpu usage. It can run on anything including PaaS like repl.it or Render and is very easy to customize.

# Why it's better than other similar apps ⚡

* works in mobile browsers, can upload file / text with ctrl+v, drag and drop, browse file or through terminal
    
* Extremely easy to set up, all you need is `go build .` or use the docker-compose.yaml and it's done
    
* Very easy for modificiations, don't like the style? pick a .css file from [here](https://github.com/dbohdan/classless-css) and replace the `static/theme.css`, don't like the layout? the html page is well commented and structured
    
* Can run on any OS or deployment platforms like repl.it, render, fly.io, etc
    
* Designed to run efficiently on any system, regardless of its CPU or memory resources
    
* Can handle gigabytes of file upload and download with fixed memory and cpu usage
    
* Encryption done right, all your data can be secured with AES & pbkdf2 for passwords
    
* Decryption is done on the fly, the encrypted data is never decrypted to the disk
    
* Short & unambiguous URL generation (with letters like ilI1 omitted) with collision detection
    
* QR code support to quickly share files to / between mobile devices
    

# URL shortener 🔗

simply paste any valid url (must start with `http://` or `https://`) to the textbox and upload

# Dont like how it looks? 🎨

pick a .css file from [here](https://github.com/dbohdan/classless-css) and replace the `static/theme.css`, or search for "classless css"

# How to build with docker 🐋

1. Download / clone this repo
    
2. Make a folder called `uploads`
    
3. Run `docker compose up`
    

# How to build without docker 📟

1. Download / clone this repo
    
2. Open terminal
    
3. Run `go build .`
    

# Settings ⚙️

You can modify the variables inside `data/settings.json`

* `fileSizeLimitMB` = limit file size (in megabytes)
    
* `textSizeLimitMB` = limit text size (in megabytes)
    
* `streamSizeLimitKB` = limit file encryption, decryption, upload & download buffer stream size (in kb) to limit memory usage
    
* `streamThrottleMS` = add throttle to the encryption, decryption, upload & download buffer to limit cpu usage
    
* `pbkdf2Iterations` = key derivation algorithm iteration, the higher the better, but 100000 should be enough
    
* `cmdUploadDefaultDurationMinute` = default file duration if you upload file through curl if duration is not specified
    

You can modify CPU/memory usage by calculating the memory usage / sec with `streamSizeLimitKB * (1000/streamThrottleMS)`, the default setting can handle 40 MB of data/second on file upload, download, encryption & decryption / second, you can tune this down if needed

# Curl upload ⬆️

`curl -F "file=@main.go" -F "duration=10" -F "pass=123" -F "burn=true" yoursite.com`  
Note that the duration, password, and burn is totally optional, you can just write `curl -F "file=@file.txt" yoursite.com` for quick upload

# Security 🔒

For maximum security, it is recommended to encrypt your file before uploading
