Jirafeau is a fork of the original project [Jyraphe](http://home.gna.org/jyraphe/) based on the 0.5 (stable version) with a **lot** of modifications.

As it's original project, Jirafeau is made in the [KISS](http://en.wikipedia.org/wiki/KISS_principle) way (Keep It Simple, Stupid).

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

# Installation
-  [Download](https://gitlab.com/mojo42/Jirafeau/repository/archive.zip) the last version of Jirafeau from GitLab
-  Upload files on your web server
-  Don't forget to set owner of uploaded files if you need to
-  Get your web browser and go to you install location (e.g. ```http://your-web-site.org/jirafeau/```) and follow instructions
-  Some options are not configured from the minimal installation wizard, you may take a look at option documentation in ```lib/config.original.php``` and customize your ```lib/config.local.php```

Note that ```lib/config.local.php``` is auto-generated during the installation.

If you don't want to go through the installation wizard, you can just copy ```config.original.php``` to ```config.local.php``` and customize it.

# Security

```var``` directory contain 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 lineto your configuration to prevent people to access to your ```var``` folder:

```RedirectMatch 301 ^/var-.* http://my.service.jirafeau ```

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.

# Few notes about server side encryption

Data encryption can be activated in options. This feature makes the server encrypt data and send the decryt key to the user (inside download URL).
The decrypt key is not stored on the server so if you loose an url, you won't be able to retrieve file content.
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:
-  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 mcrypt php module.
-  File de-duplication will stop to work (as we can't compare two encrypted files).
-  Be sure your server do not log client's requests.
-  Don't forget to enable https.

In a next step, encryption will be made by the client (in javascript), see issue #10.

# FAQ

### Can I add a new language in Jirafeau?

Of-course ! Translations are easy to make and no technical knowledge is required.

Simply go to [Jirafeau's Weblate](https://hosted.weblate.org/projects/jirafeau/master/).

If you want to add a new language in the list, feel free to contact us or leave a comment in ticket #9.

We would like to thanks to anonymous contributors on weblate. :)

### How do I upgrade my Jirafeau?

If you have installed Jirafeau using git, it's pretty simple: just make a git pull and chown/chmod files who have the owner changed.

If you have installed Jirafeau just by uploading files on your server, you can take the [last version](https://gitlab.com/mojo42/Jirafeau/repository/archive.zip), overwrite files and chown/chmod files if needed.

After upgrading, you can compare your ```lib/config.local.php``` and ```lib/config.original.php``` to see if new configuration items are available.

If you have some troubles:
- It should probably come from your ```lib/config.local.php``` (configuration syntax may have changed). Just compare it with ```lib/config.original.php```
- Check owner/permissions of your files.

Anyway you should off-course make a backup of your current installation before doing anything. :)

### 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](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#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](https://gitlab.com/mojo42/Jirafeau/blob/master/lib/config.original.php).

### I have some troubles with IE

If you have some strange behavior with IE, you may configure [compatibility mode](http://feedback.dominknow.com/knowledgebase/articles/159097-internet-explorer-ie8-ie9-ie10-and-ie11-compat).

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

### I found a bug, what should I do?

Feel free to open a bug in the [GitLab's issues](https://gitlab.com/mojo42/Jirafeau/issues).

### How to set maximum file size?

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

For browsers who does not support HTML5 file API, the limitation come from PHP configuration.
You have to set [post_max_size](https://php.net/manual/en/ini.core.php#ini.post-max-size) and [upload_max_filesize](https://php.net/manual/en/ini.core.php#ini.upload-max-filesize) in your php configuration.

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](https://gitlab.com/mojo42/Jirafeau/blob/master/lib/config.original.php).
If you want to change an option, just edit your ```lib/config.local.php```.

### 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.

### Why forking?

The original project seems not to be continued anymore and I prefer to add more features and increase security from a stable version.

### What can we expect in the future?

Check [issues](https://gitlab.com/mojo42/Jirafeau/issues) to check open bugs and incoming new stuff. :)

### What is the Jirafeau's license?

Jirafeau is licensed under [AGPLv3](https://gitlab.com/mojo42/Jirafeau/blob/master/COPYING).

### How do I modify the TOS (terms of use)?

Just edit ```tos.php``` and configure ```$org``` and ```$contact``` variables.

### What about this file deduplication thing?

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

This mean that if some people upload several times the same file, this will only store one time the file and increment a counter.

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

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

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

As explained in the previous question, files with the same md5 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.
