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.
A PHP Framework that allows you to encode and decode arbitrary ASN.1 structures
using the ITU-T X.690 Encoding Rules.
This encoding is very frequently used in X.509 PKI environments or the communication between heterogeneous computer systems.
The API allows you to encode ASN.1 structures to create binary data such as certificate
signing requests (CSR), X.509 certificates or certificate revocation lists (CRL).
PHPASN1 can also read BER encoded binary data into separate PHP objects that can be manipulated by the user and reencoded afterwards.
The changelog can now be found at CHANGELOG.md.
Dependencies
PHPASN1 requires at least PHP 7 and the gmp extension.
Installation
The preferred way to install this library is to rely on Composer:
Usage
Encoding ASN.1 Structures
PHPASN1 offers you a class for each of the implemented ASN.1 universal types.
The constructors should be pretty self explanatory so you should have no big trouble getting started.
All data will be encoded using DER encoding
Decoding binary data
Decoding BER encoded binary data is just as easy as encoding it:
You can use this function to make sure your data has exactly the format you are expecting.
Composer command for our command line client (download client)This client runs in each environment. You don't need a specific PHP version etc. The first 20 API calls are free.Standard composer command
