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 phpass
PHP Password Library
The PHP Password Library is designed to ease the tasks associated with working with passwords in PHP. It is capable of generating strong cryptographic password hashes, verifying supplied password strings against those hashes, and calculating the strength of a password string using various algorithms.
This project was inspired by Openwall's portable hashing library for PHP and PassLib for Python.
Features
- Create and verify secure password hashes with only a few lines of code.
- Supports bcrypt and PBKDF2 out of the box.
- Easily extend to support additional hashing methods.
- Additional password strength component based on well-known algorithms.
- Follows the PSR-0 standard for autoloader compatibility.
Installation
PEAR
Installing via PEAR is a simple matter of including the PEAR channel and installing the rych/PHPass package.
Composer
Composer is an easy way to manage dependencies in your PHP projects. The PHP Password Library can be found in the default Packagist repository.
After installing Composer into your project, the PHP Password Library can be installed by adding the following lines to your composer.json file and running the Composer command line tool:
Usage
Hashing passwords
The library provides the ability to generate strong cryptographic hashes of user passwords using a variety of methods. Each method may be customized as needed, and may also be combined with HMAC hashing when using the base class.
Examples
Use the default bcrypt adapter:
Use the PBKDF2 adapter:
Create and verify a password hash:
Calculating password strength
There are many different ways to calculate the relative strength of a given password, and this library supports a few of the most common. Each method returns a number which represents the estimated entropy for the given password. It's up to the developer to determine the minimum calculated entropy to accept. Combined with a sensible password policy, this can be a valuable tool in selecting strong passwords.
Examples
Calculate a password's entropy using NIST recommendations:
Calculate a password's entropy using Wolfram Alpha's algorithm:
