Blockchain-FileStorage

This a masters research project. This project is an effort to create a better more secure method for data storage.

There are three specific aspects to the project.

1. The ledger
2. The data front
3. The data storage its self.

Server Task List:

• 1. Main system (app.js)

• 2. Communication (network.js)

  • 2.1 TCP server

• 3. Ledger handling system (ledger.js)

  • 3.1 Data inserting (called from API)

• 4. Data handling (functions.js)

  • 4.1 Data storing
  • 4.2 Data security
  • 4.3 Data Hashing
  • 4.4 Data distribution

  make connection to other Nodes listen for other nodes connection

  update nodes list

  login to any node to upload Data

  send my public key / hash

  on insert request take data then break up and encrypt the data using the users private key

  var encryptStringWithRsaPublicKey = function(toEncrypt, relativeOrAbsolutePathToPublicKey) { var absolutePath = path.resolve(relativeOrAbsolutePathToPublicKey); var publicKey = fs.readFileSync(absolutePath, "utf8"); var buffer = Buffer.from(toEncrypt); var encrypted = crypto.publicEncrypt(publicKey, buffer); return encrypted.toString("base64"); };

  var decryptStringWithRsaPrivateKey = function(toDecrypt, relativeOrAbsolutePathtoPrivateKey) { var absolutePath = path.resolve(relativeOrAbsolutePathtoPrivateKey); var privateKey = fs.readFileSync(absolutePath, "utf8"); var buffer = Buffer.from(toDecrypt, "base64"); var decrypted = crypto.privateDecrypt(privateKey, buffer); return decrypted.toString("utf8"); };

  module.exports = { encryptStringWithRsaPublicKey: encryptStringWithRsaPublicKey, decryptStringWithRsaPrivateKey: decryptStringWithRsaPrivateKey }
