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 crypt
Crypt Component
The Crypt component provides methods for generating random numbers and strings, also, password hashing and password
hash verification and methods for encryption and decryption of strings. Internally it uses cryptographically secure methods.
Disclaimer: The library was not reviewed by a security expert.
Install the component
The best way to install the component is using Composer. This library requires that you also add a repository to your composer.json file.
For additional versions of the package, visit the Packagist page.
Using Crypt
Generate random integers
To generate a random integer you just have to pass the range to the Crypt instance:
Generate random strings
When you want to generate random string, you have several options. You can call the general generateRandomString method,
or you can call generateUserReadableString method to get a more user-readable string that doesn't contain any special
characters. There is also a method called generateHardReadableString that, among letters and numbers, uses special
characters to make the string more "harder".
Here are a few examples:
Password hashing and validation
Encrypting and decrypting strings
Crypt config
There are three different internal crypt libraries that you can choose from:
- OpenSSL - this is the default library
- Sodium - library that utilizes paragonie/halite internally for password hashing, password verification, encryption and decryption. Please note that this library is highly CPU intensive.
- Mcrypt - this is the depricated library which will be removed once we hit PHP v7.2
To switch between libraries, just set a different Bridge in your configuration:
and then in your code just call:
Custom Crypt driver
To create a custom Crypt driver, first you need to create a class that implements \Webiny\Component\Crypt\Bridge\CryptInterface.
Once you have implemented all the requested methods, you now need to change the Bridge path
inside your component configuration.
Resources
To run unit tests, you need to use the following command:
$ cd path/to/Webiny/Component/Crypt/
$ composer.phar install
$ phpunit
