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 asn1

ASN.1

Build Status Scrutinizer Code Quality Coverage Status License

A PHP library for X.690 Abstract Syntax Notation One (ASN.1) Distinguished Encoding Rules (DER) encoding and decoding.

Requirements

Installation

This library is available on Packagist.

Usage

The general idea is that each ASN.1 type has its corresponding PHP class, that knows the details of encoding and decoding the specific type.

To decode DER data, use fromDER static method of the expected type. To encode object to DER, use toDER instance method.

Many methods return an UnspecifiedType object, that works as an intermediate wrapper with accessor methods ensuring type safety.

All objects are immutable and method chaining is promoted for the fluency of the API. Exception shall be thrown on errors.

Code Examples

Here are some simple usage examples. Namespaces are omitted for brevity.

Encode

Encode a sequence containing a UTF-8 string, an integer and an explicitly tagged object identifier, conforming to the following ASN.1 specification:

Decode

Decode DER encoding from above.

Real-World Examples

See the following for more practical real-world usage examples.
