  3# What is NoPaste?
  4
  5[NoPaste](https://nopaste.ml/) is an open-source website similar to Pastebin where you can store any piece of code, and generate links for easy sharing
  6
  7However, what makes NoPaste special is that it works with **no database**, and **no back-end code**. Instead, the data is compressed and **stored entirely in the link** that you share, nowhere else!
  8
  9### Because of this design:
 10
 11-   🗑️ Your data **cannot be deleted** from NoPaste
 12-   🔞 Your data **cannot be censored**
 13-   👁️ The server hosting NoPaste (or any clone of it) **cannot read or access** your data
 14-   ⏳ Your data will be accessible **forever** (as long as you have the link)
 15-   🔀 You can access your data on **every NoPaste clone**, including [your own](https://github.com/bokub/nopaste/wiki/Deploy-your-own-version-of-NoPaste)
 16-   🔍 Google **will not index** your data, even if your link is public
 17
 18> **Note:** This project is a copy of [Topaz's paste service][topaz-example], with a reworked design and a few additional features (syntax highlighting, line numbers, offline usage, embedding...)
 19
 20## How it works
 21
 22When you click on "Generate Link", NoPaste compresses the whole text using the
 23[LZMA algorithm](https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Markov_chain_algorithm), encodes it in
 24[Base64](https://en.wikipedia.org/wiki/Base64), and puts it in the optional URL fragment, after the first `#` symbol: `nopaste.ml/#<your data goes here>`
 25
 26When you open a link, NoPaste reads, decodes, and decompresses whatever is after the `#`, and displays the result in the editor.
 27
 28This process is done entirely **in your browser**, and the web server hosting NoPaste [never has access to the fragment](https://en.wikipedia.org/wiki/Fragment_identifier)
 29
 30For example, [this is the CSS code used by NoPaste][example]
 31
 32## Other features
 33
 34### Embedded NoPaste snippets
 35
 36You can include NoPaste code snippets into your own website by clicking the _Embed_ button and using the generated HTML code.
 37
 38Here is an example of generated code and how it looks (click on the screenshot to see the interactive version)
 39
 40```html

 50
 51Feel free to edit the `height` and `width` attributes, so they suit your needs
 52
 53### Offline usage
 54
 55When you visit NoPaste for the first time, its code is saved in your browser cache. After that, every NoPaste link you open
 56will load really quick, even if your internet connexion is slow.
 57
 58What if you have no internet connexion at all? No problem, NoPaste will still work perfectly!
 59
 60### Editor features
 61
 62-   Syntax highlighting (use the language selector)
 63-   Enable / disable line wrapping (use the button next to the language selector)
 64-   Delete line (`Ctrl+D`)
 65-   Multiple cursors (`Ctrl+Click`)
 66-   Usual keyboard shortuts (`Ctrl+A`, `Ctrl+Z`, `Ctrl+Y`...)
 67
 68## Maximum sizes for links
 69
 70NoPaste is great for sharing code snippets on various platforms.
 71
 72These are the maximum link lengths on some apps and browsers.
 73
 74| App     | Max length |
 75| ------- | ---------- |
 76| Reddit  | 10,000     |

 82| Browser         | Max length                | Notes                                   |
 83| --------------- | ------------------------- | --------------------------------------- |
 84| Google Chrome   | (win) 32,779 (mac) 10,000 | Will not display, but larger links work |

 88| Android         | 8,192                     |                                         |
 89| Safari          | Lots                      |                                         |

 91## Generate NoPaste links
 92
 93NoPaste links can be created easily from your system's command line:
 94
 95```bash
 96# Linux
 97echo -n 'Hello World' | lzma | base64 -w0 | xargs -0 printf "https://nopaste.ml/#%s\n"
 98
 99# Mac
100echo -n 'Hello World' | lzma | base64 | xargs -0 printf "https://nopaste.ml/#%s\n"
101
102# Windows / WSL / Linux
103echo -n 'Hello World' | xz --format=lzma | base64 -w0 | printf "https://nopaste.ml/#%s\n" "$(cat -)"
104```
105
106## Deploy your own version of NoPaste
107
108NoPaste is just a bunch of static files, making it really easy to deploy on any kind of file server.
109
110Read [the wiki](https://github.com/bokub/nopaste/wiki/Deploy-your-own-version-of-NoPaste) to see how you can deploy your own version of NoPaste for free using Github Pages
