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.

Informations about the package security

Security

license build coverage

The Security library provides various function related to security such as hashing, encryption, decryption and secure random string generation.

Installation

To install this package

Hashing

Hashing Strings (Not Passwords)

The default hashing algorithm used is sha256.

To hash a string (not password)

To hash a string with a pepper (also incorrectly known as salt).

To change the hashing type

For a full list of supported algorithms

Hashing Passwords

The Security utility hashes passwords using best practices, currently this is bcrypt which is considered very secure.

To verify the password is correct

Encryption

Generating a Secure Key

To encrypt and decrypt a string you will need a key, you can generate a random secure key.

The key length must be 32 bytes (256 bits) to use with the encryption decryption functions.

Encrypting Text

To encrypt a string

Decrypting Text

To decrypt an encrypted string

Random Strings

To generate a cryptographically secure hexadecimal random string, the default length is 16. (This is an alias for hex)

Different Encodings

You can generate secure random strings with different encoding.

UID

If you need to generate a unique id, and don't need to use a UUID, then the UID method provides a more memory and disk space efficient way when working with unique ids.

If you are generating a API token or another form of string that a user might need to type in, then use Security::random or Security::uuid instead since these use lower case characters.

To generate a cryptographically secure unique id (UID) using base62 with a default length of 16.

UUID

The Security class can generate both version 4 and version 1 UUIDs.

To generate a random UUID (version 4)

For a version 1 UUID, set MAC address to true, this will try to find the MAC address on Linux systems or generate a random one.

You can also set the MAC address manually.
