akamai-filehash-helper

A Node.js module for extracting filehash values from obfuscated JavaScript code using Babel AST parsing.

Overview

This project extracts filehash values from obfuscated JavaScript files, particularly those related to Akamai sensor data. It uses Babel's Abstract Syntax Tree (AST) parser to analyze and extract the necessary data structures from complex, obfuscated code.

Original Source

This project is based on the original work from:

• Repository: glizzykingdreko/akamai-v3-sensor-data-helper

Installation

npm install akamai-filehash-helper

Or using pnpm:

pnpm install akamai-filehash-helper

Usage

import extractFileHash from 'akamai-filehash-helper';
import fs from 'fs';

// Read the obfuscated JavaScript file
const fileContent = fs.readFileSync('path/to/obfuscated-file.js', 'utf-8');

// Extract the filehash
const fileHash = extractFileHash(fileContent);

console.log('Extracted filehash:', fileHash);

API

extractFileHash(fileContent: string): number

Extracts and returns the filehash value from the provided JavaScript code.

Parameters:

• fileContent (string): The content of the obfuscated JavaScript file

Returns:

• number: The extracted filehash value

Throws:

• Error: If the expected structure is not found in the code or if required elements are missing
