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 phpasn1
PHPASN1
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 7.0 and either the gmp or bcmath extension.
Support for older PHP versions (i.e. PHP 5.6) was dropped starting with v2.0.
If you must use an outdated PHP version consider using PHPASN v1.5.
For the loading of object identifier names directly from the web curl is used.
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:
If you already know exactly how your expected data should look like you can use the FG\ASN1\TemplateParser:
You can use this function to make sure your data has exactly the format you are expecting.
Navigating decoded data
All constructed classes (i.e. Sequence and Set) can be navigated by array access or using an iterator.

How do I contribute?
If you found an issue or have a question submit a github issue with detailed information.
In case you already know what caused the issue and feel in the mood to fix it, your code contributions are always welcome. Just fork the repository, implement your changes and make sure that you covered everything with tests. Afterwards submit a pull request via github and be a little patient :) I usually try to comment and/or merge as soon as possible.
