Project README Overview

This project involves uploading files to IPFS via Pinata, verifying them through a web interface, and interacting with Ethereum smart contracts to store verification status. Users can upload files, verify them through a modal interface, and track verification status via the blockchain and local storage. Technologies Used

IPFS (InterPlanetary File System): for decentralized file storage.
Pinata: as a Pinning Service to interact with IPFS.
Web3.js: for interacting with Ethereum blockchain.
HTML, CSS, JavaScript: for the frontend and basic styling.
CryptoJS: for hashing functions.

Setup Instructions

Clone the Repository

bash

git clone https://github.com/SurajKMUllura/Securing-academic-credentials-and-skillset-using-Blockchain-technology
cd repository

Install Dependencies

No specific dependencies mentioned, ensure you have a modern web browser and an active internet connection.

Configure Pinata API Keys

Replace pinataApiKey and pinataSecretApiKey in the code with your Pinata API keys. These keys are necessary for file pinning and retrieval.

Run the Application

Open index.html in a web browser.

Usage Uploading Files

Use the uploadFile or uploadSkillsetCertification functions to upload files to Pinata. Choose file type and provide necessary details like email and file description.

Verifying Files

Click on the verification button associated with a file to initiate verification. Answer verification questions in the modal dialog that appears.

Managing Files

View uploaded files and their verification status. Files are displayed based on the user's address.

Returns: IPFS hash of the uploaded file.

handleVerificationSubmission()

Description: Handles verification submission, interacts with Ethereum smart contracts.
Processes:
    Retrieves user answers from the modal.
    Updates verification status based on answers.
    Updates UI and sends email notification on verification completion.

fetchAllFilesData()
