asn 1 parser in C Python

Creating an ASN.1 parser in C or Python can be a complex task, but I'll provide you with a high-level overview of how to get started and a simple code example in both C and Python to give you a basic understanding of the process.
ASN.1 (Abstract Syntax Notation One) is a standard interface description language used for defining data structures that can be serialized and deserialized in a cross-platform way. It's often used in networking protocols, security certificates (like X.509), and other applications where data interchange between different systems is crucial.
ASN.1 data is structured as a series of types, each with a unique tag and a length field. The basic structure of an ASN.1 object looks like this:
Here's a simplified example of an ASN.1 parser in C:
This C code provides a basic ASN.1 parser that can parse some simple ASN.1 structures.
Here's a simplified example of an ASN.1 parser in Python using the pyasn1 library:
In this Python example, we use the pyasn1 library to decode an ASN.1 INTEGER object. This library simplifies the process of parsing ASN.1 data in Python.
Please note that parsing more complex ASN.1 structures or implementing custom types may require additional code and handling. ASN.1 encoding can vary in complexity depending on the specific application and data being used.
