encrypted-file-system's Introduction

Encrypted File System

The goal of the project is to encrypt the file and perform read, write, and cut operations efficiently.
Efficiency in measured terms of number of read / write files and performance in terms of encrypt and decrypt functions. At the same time, the security should be intact for the files, so that any tampering of the files is noticed.

The main code is there is EFS.java and only basic functions from Utility.java are used.

Functions like CTR Mode of Encryption / Decryption with AES/ECB/NoPadding, HMAC are implemented manually.

List File

Need to log a file called list file that will contain the list of files that were scanned in a run.

This file will be referred (in the status file) by the next run, the files that were processed and can be compared and uploaded again.

Log file

Log file should have max of say 10 days and archive upto 30 days (tar.gz).

Both features should be implemented.

Config folder base location as per system (ubuntu/mac etc)

Cloud's to sync for each folder

Option for the cloud to sync and the cloud configuration name

Test case in python to generate 100k files

Python test case to generate 100k files and folders nested internally

Cloud configuration details

Each cloud will have it's own details (like token, nickname etc).
pojo and file to create and write those

Status file format

Basic things to include in the status file:
