Jirafeau

Welcome to the official Jirafeau project, an Open-Source software.

Jirafeau is a "one-click-filesharing": Select your file, upload, share a link. That's it.

See jirafeau.net for a demo.

DISCLAMER

This project is a fork of the discontinued project by Jérôme Jutteau.

If you've also forked the original project, feel free to mention it in comments. Jérôme will add it there.

In this repository we are aiming to continue development of the original Jirafeau project. Feel free to contribute to this fork by participating in discussions and providing merge requests, so we can build the best version of Jirafeau together!

Main features

• One upload → one download link and one delete link
• Send any large files (thanks to the HTML5 file API → PHP post_max_size limit not relevant)
• Shows upload progress: speed, percentage and remaining upload time
• Preview content in browser (if possible)
• Optional password protection (for uploading or downloading)
• Option to require, check or generate file download passwords
• Set expiration time for downloads
• Option to self-destruct after first download
• Shortened URLs using Base64 encoding
• Maximal upload size configurable
• No database, only use basic PHP
• Simple language support with a lot of languages
• File level deduplication for storage optimization (does store duplicate files only once, but generate multiple links)
• Optional data encryption
• Small administration interface
• CLI script to remove expired files automatically with a cronjob
• Basic, adaptable "Terms Of Service" page
• Basic API
• Bash script to upload files via command line
• Themes

Jirafeau is a fork of the original project Jyraphe based on the 0.5 (stable version) with a lot of modifications.

As it's original project, Jirafeau is made in the KISS way (Keep It Simple, Stupid).

Jirafeau project won't evolve to a file manager and will focus to keep a very few dependencies.

Installation

This shows how to install Jirafeau by your own, it's quite simple but you can also use a docker image or build it yourself. Check docker folder for more information.

System requirements:

• PHP >= 7.4
• Optional, but recommended: Git >= 2.7
• No database required, no mail required

Installation steps:

• Clone the repository or download the latest release from GitLab onto your webserver
• Set owner & group according to your webserver
• A) Setup with the installation wizard (web):
  • Open your browser and go to your installed location, eg. https://example.com/jirafeau/
  • The script will redirect to you to a minimal installation wizard to set up all required options
  • All optional parameters may be set in lib/config.local.php, take a look at lib/config.original.php to see all default values
• B) Setup without the installation wizard (cli):
  • Just copy lib/config.original.php to lib/config.local.php and customize it

Troubleshooting

If you have some troubles, consider the following cases

• Check your /lib/config.local.php file and compare it with /lib/config.original.php, the configuration syntax or a parameter may have changed
• Check owner and permissions of your files
• Set debug option to true to check any warning or error

Security

var directory contains all files and links. It is randomly named to limit access but you may add better protection to prevent un-authorized access to it. You have several options:

• Configure a .htaccess
• Move var folder to a place on your server which can't be directly accessed
• Disable automatic listing on your web server config or place a index.html in var's sub-directory (this is a limited solution)

If you are using Apache, you can add the following lines to your configuration to prevent people to access to your var folder:

<LocationMatch "^/var-*">
    Require all denied
</LocationMatch>

Or you can put a .htaccess file containing this into your var folder:

Require all denied

If you are using nginx, you can add the following to your $vhost.conf:

location ~ /var-.* {
    deny all;
    return 404;
}

If you are using lighttpd, you can deny access to var folder in your configuration:

$HTTP["url"] =~ "^/var-*" {
         url.access-deny = ("")
}

You should also remove un-necessessary write access once the installation is done (ex: configuration file). An other obvious basic security is to let access users to the site by HTTPS (make sure web_root in you config.local.php is set with https).

Server side encryption

Data encryption can be activated in options. This feature makes the server encrypt data and send the decrypt key to the user (inside download URL). The decrypt key is not stored on the server so if you lose the download URL, you won't be able to retrieve file content. Encryption is configured to use XChaCha20-Poly1305. In case of security troubles on the server, attacker won't be able to access files.

By activating this feature, you have to be aware of few things:

• This is no end-to-end encryption! Although the file should be sent to server using HTTPS, the file is unencrypted on the server for a very short time. To have end-to-end encryption, you need to encrypt the file yourself.
• Data encryption has a cost (CPU) and it takes more time for downloads to complete once file sent.
• During the download, the server will decrypt on the fly (and use resource).
• This feature needs to have the Sodium PHP module.
• File de-duplication will stop to work (as we can't compare two encrypted files).
• Be sure your server does not log client's requests.
• Don't forget to enable HTTPS.

In a next step, encryption will be made by the client (in JavaScript), which will also give us end-to-end encryption.

Known issues

• There is an issue with asynchronous uploads not working in Chromium-based browsers on servers with HTTP/3 enabled. This seems to be caused by a bug in Chromium.
  This bug can be worked around by setting max_upload_chunk_size_bytes to a value of around 3000000 to 5000000 (3 to 5MB) which is default since Jirafeau version 4.7.1. Please note that you have to change this value manually if you're upgrading from a version of Jirafeau older than 4.7.1!
  Thanks to slt for reporting this and for finding a workaround.

FAQ

Can I add a new language in Jirafeau?

Of course! The best way is to create a new JSON file under lib/locales and open a merge request.

Thanks to all contributors ! :)

How do I upgrade my Jirafeau?

See change log and upgrade procedure in CHANGELOG.md.

How can I limit upload access?

There are two ways to limit upload access (but not download):

• you can set one or more passwords in order to access the upload interface, or/and
• you can configure a list of authorized IP (CIDR notation) which are allowed to access to the upload page

Check documentation of upload_password and upload_ip parameters in lib/config.original.php.

How can I automatize the cleaning of old (expired) files?

You can call the admin.php script from the command line (CLI) with the clean_expired or clean_async commands: sudo -u www-data php admin.php clean_expired.

Then the command can be placed in a cron file to automatize the process. For example:

# m h dom mon dow user  command
12 3    * * *   www-data  php /path/to/jirafeau/admin.php clean_expired
16 3    * * *   www-data  php /path/to/jirafeau/admin.php clean_async

I have some troubles with IE

If you have some strange behavior with IE, you may configure compatibility mode.

Anyway I would recommend you to use another web browser. :)

How can I change the theme?

You may change the default theme to any of the existing ones or a custom.

Open your lib/config.local.php and change setting in the style key to the name of any folder in the /media directory. If you want to change the theme for dark mode, you have to set the dark_style key in the config file.

Hint: To create a custom theme just copy the courgette folder and name your theme custom (this way it will be ignored by git and not overwritten during updates). If you want to create a custom theme for dark mode, you have to put it in a folder named dark-custom. You are invited to enhance the existing themes and send pull requests however.

I found a bug, what should I do?

Feel free to open a bug in the GitLab's issues. If you can, please copy-paste information related to bug opening provided in admin interface. Admin interface can be reached by accessing /admin.php.

How to set maximum file size?

If your browser supports the HTML5 file API, you can send files as big as you want.

For browsers not supporting the HTML5 file API, the limitation comes from PHP configuration. You have to set post_max_size and upload_max_filesize in your php configuration. Note that nginx setups may requiere to configure client_max_body_size.

If you don't want to allow unlimited upload size, you can still setup a maximal file size in Jirafeau's setting (see maximal_upload_size in your configuration)

How can I edit an option?

Documentation of all default options are located in /lib/config.original.php. If you want to change an option, just edit your /lib/config.local.php.

How can I change the Terms of Service?

The license text on the "Terms of Service" page, which is shipped with the default installation, is based on the "Open Source Initiative Terms of Service".

To change this text simply copy the file /lib/tos.original.txt, rename it to /lib/tos.local.txt and adapt it to your own needs.

If you update the installation, then only the tos.original.txt file may change eventually, not your tos.local.txt file.

How can I access the admin interface?

Just go to /admin.php.

How can I use the scripting interface (API)?

Simply go to /script.php with your web browser.

My downloads are incomplete or my uploads fails

Be sure your PHP installation is not using safe mode, it may cause timeouts.

If you're using nginx, you might need to increase client_max_body_size or remove the restriction altogether. In your nginx.conf:

http {
    # disable max upload size
    client_max_body_size 0;
    # add timeouts for very large uploads
    client_header_timeout 30m;
    client_body_timeout 30m;
}

How can I monitor the use of my Jirafeau instance?

You may use Munin and simple scripts to collect the number of files in the Jirafeau instance as well as the disk space occupied by all the files. You can consult this web page.

Why forking?

In this repository we are aiming to continue development of the original Jirafeau project. We plan to add more features and increase security from a stable version.

What can we expect in the future?

Check issues to check open bugs and incoming new stuff. :)

What about this file deduplication thing?

Jirafeau can use a very simple file level deduplication for storage optimization.

This means that if some people upload the same file several times, the file will only be stored once and a counter will be incremented.

If someone use his/her delete link or an admin cleans expired links, this will decrement the counter corresponding to the file.

When the counter falls to zero, the file is destroyed.

In order to know if a newly uploaded file already exist, Jirafeau will hash the file using MD5 by default but other methods are available (see file_hash documentation in lib/config.original.php).

This feature is disabled by default and can be enabled through the file_hash option.

What is the difference between "delete link" and "delete file and links" in admin interface?

When file deduplication feature is enabled, files with the same hash are not duplicated and a reference counter stores the number of links pointing to a single file. So:

• The button "delete link" will delete the reference to the file but might not destroy the file.
• The button "delete file and links" will delete all references pointing to the file and will destroy the file.

How to contact someone from Jirafeau?

Feel free to create an issue if you found a bug.

Can I buy you a coffee?

You can drop few bucks for Jérôme Jutteau

Many Thanks <3
