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 crypto
crypto()
A two-way encryption method/class for PHP.
Requirements:
This function requires that your server has PHP (7.2.0+) and that you have sodium installed and enabled on your server.
Versions:

With Composer:

Why are you not using composer? You can directly download the php file and upload it to your server and include the file however it is you normally include php files.
Key Generation:
For each user of your website/service you should generate a key that is stored somewhere on your server (best to do so in a sub root directory.)
If you use a KMS, just make the necessary changes to not use local paths and rather the paths to your KMS api. That could be your own local KMS hardware or a KMS service such as what AWS and Google Cloud and other KMS providers offer.
You should wrap your call to generate a new key in a try/catch in order to handle Exception messages.
An example would be something along the lines of this, handling the Exception error messages in whatever way you prefer.
Encryption/Decryption Function Variables:
The crypto() class has three variables that need to be passed for encryption and decryption:
$keyPath= the path to an individual users cryptoKey, generated by(new crypto($keyPath))->generateKey();and stored somewhere on your server, preferably sub-root.$Content= The content that you want to encrypt or decrypt.eord= The direction of action, eitherefor encryption, ordfor decryption.
