The README.md

ASN.1

Build Status Scrutinizer Code Quality Coverage Status License, (*1)

A PHP library for X.690 Abstract Syntax Notation One (ASN.1) Distinguished Encoding Rules (DER) encoding and decoding., (*2)

Requirements

  • PHP >=7.2
  • gmp
  • mbstring

Installation

This library is available on Packagist., (*3)

composer require sop/asn1

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., (*4)

To decode DER data, use fromDER static method of the expected type. To encode object to DER, use toDER instance method., (*5)

Many methods return an UnspecifiedType object, that works as an intermediate wrapper with accessor methods ensuring type safety., (*6)

All objects are immutable and method chaining is promoted for the fluency of the API. Exception shall be thrown on errors., (*7)

Code Examples

Here are some simple usage examples. Namespaces are omitted for brevity., (*8)

Encode

Encode a sequence containing a UTF-8 string, an integer and an explicitly tagged object identifier, conforming to the following ASN.1 specification:, (*9)

```asn.1 Example ::= SEQUENCE { greeting UTF8String, answer INTEGER, type [1] EXPLICIT OBJECT IDENTIFIER }, (*10)


```php
$seq = new Sequence(
    new UTF8String('Hello'),
    new Integer(42),
    new ExplicitlyTaggedType(
        1, new ObjectIdentifier('1.3.6.1.3'))
);
$der = $seq->toDER();

Decode

Decode DER encoding from above., (*11)

$seq = UnspecifiedType::fromDER($der)->asSequence();
$greeting = $seq->at(0)->asUTF8String()->string();
$answer = $seq->at(1)->asInteger()->intNumber();
$type = $seq->at(2)->asTagged()->asExplicit()->asObjectIdentifier()->oid();

Real-World Examples

See the following for more practical real-world usage examples., (*12)
