FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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.
Please rate this library. Is it a good library?

OVERVIEW

pop-crypt provides various interfaces to a assist in creating and verifying encryption hashes. The supported encryption hashes are:

pop-crypt is a component of the Pop PHP Framework.

INSTALL

Install pop-crypt using Composer.

composer require popphp/pop-crypt

BASIC USAGE

Create and verify a hash with Crypt

Using crypt is the simplest way to create an encrypted hash. It's best to use a strong, random salt for better security.

Create and verify a hash with Bcrypt

Bcrypt is considered one of the stronger methods of creating encrypted hashes. With it, you can specify the prefix and performance cost. The higher the cost, the stronger the hash. However, the higher the cost, the longer it will take to generate the hash. The cost range values are between '04' and '31'.

Again, it's best to use a strong salt for better security. In fact, it's considered a best practice to use a strong random string as the salt, which the Bcrypt class generates automatically for you if you don't specify one.

Create and verify a hash with Md5

This isn't to be confused with the basic md5() function built into PHP. It is not recommended to use that function for password hashing as it only generates a 32-character hexadecimal number and is vulnerable to dictionary attacks.

As before, it's best to use a strong salt for better security. In fact, it's considered a best practice to use a strong random string as the salt. Like Bcrypt, the Md5 class will automatically generate a random salt for you if you don't specify one.

Create and verify a hash with Sha

This isn't to be confused with the basic sha1() function built into PHP. Like md5(), it is not recommended to use that function for password hashing as it only generates a 40-character hexadecimal number and is vulnerable to dictionary attacks.

With the Sha class, you can set the bits (256 or 515) and rounds (between 1000 and 999999999), which will affect the performance and strength of the hash.

As before, it's best to use a strong salt for better security. In fact, it's considered a best practice to use a strong random string as the salt. Like Bcrypt and Md5, the Sha class will automatically generate a random salt for you if you don't specify one.

Two-way encryption hashing with Mcrypt

Mcrypt provides a way to create a two-way encryption hash, in which you can create an unreadable encrypted hash and then decrypt it later to retrieve the value of it.

You have several parameters that you can set with the Mcrypt class to help control the performance and security of the hashing. These values are set by default, or you can set them yourself:

As with the others, it's best to use a strong salt for better security. In fact, it's considered a best practice to use a strong random string as the salt. Like the others, the Mcrypt class will automatically generate a random salt for you if you don't specify one.

You can then retrieve the value of the hash by decrypting it:
