FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package encoding_toolbox
net-tools/encoding_toolbox
Composer library providing client-side Javascript encoding/PHP-obfuscating functionnalities
This package contains an HTML page (and also required CSS and JS files) you can use to quickly :
- encode/decode data to/from base64
- compute sha256 and md5 for some data
- obfuscate/un-obfuscate sensitive strings in PHP scripts
Setup instructions
To install net-tools/encoding_toolbox package, just require it through composer : require net-tools/encoding_toolbox:^1.0.0.
You can also download the full release and copy the files in any folder (that's pure client-side code, no PHP, no autoloading, etc.) and open your browser with encoding_toolbox.html.
How to use ?
The HTML page is rather simple.
The left side provides encoding functionnalities, and the right side contains the decoding stuff. You enter (or paste) the data to encode/decode, obfuscate/unobfuscate, compute in the top textarea and you click on the desired action button. The encoded/decoded, obfuscated/un-obfuscated data will be displayed in the bottom textarea, and selected when you click on it (allowing an easy CTRL+C copy).
You will note that there's no decoding actions for sha256 and md5. If this is not obvious for you, please refer to Wikipedia or any other source about sha256 and md5 : they are hash algorithms, not crypt-algorithm that can be reversed.
Confidentiality
As this is pure client-side Javascript code, all processes run on your computer, so your sensitive data won't never 'go outside'.
Obfuscation
The obfuscate functionnality can be useful when you don't want a password (or any sensitive data) to appear clearly in a PHP script. In case your host is hacked, the PHP files could be automatically scanned for passwords. Clear passwords in source code are not a good practice.
That's why we must write passwords in another way. The easiest way would be something like $pass = base64_decode('MTIzNA=='), encoding the '1234' password. However, a base64 string can also be easily scanned in a script by an hacker automated process (looking for strings with only letters, digits, +, / and =) and immediately decoded to the password.
My obfuscation process uses base64, but also string 'crypting' functions and variable functions. I wrote 'crypting' with quotes, as the functions used are not cryptographic functions ; they just transform the original string with a simple code algorithm.
The aim is not to produce strong-crypted strings, but to write sensitive data in script with some minimal encoding that an automated process may not reverse (without guidance for an human eye, understanding the encoding process used).
Un-obfuscation
If one day you wan't to get the original data obfuscated, just copy paste the obfuscate code, and hit 'un-obfuscate'. Please be sure to copy/paste the exact data eval(base64_decode(...)).
In case one day this library or my website are not online anymore, you may copy this package on you computer. That will allow you to unobfuscate the data (remember, this is pure client-side Javascript code, you don't need a web server to run the code).
