hullencrypt 0.0.4

A selfmade cryptolib for sharing passwords in a tree structure

HullEncrypt

Idea

HullEncrypt (base and gui) are inspired by Skeleton

GUI

The GUI is not working as of 3a7b9ea

Concept

Parent -> Node -> Child -> Child

Every node can be unlocked by it's parent, or it's password, and can unlock all of it's children this is because the childs key is generated by hashing the Parent's key and the Nodes UUID

Security

A user wich has been given an unlocked Node can't get the parents key with the knowledge of the childs key as it is hashed + salted to get the childs key, allowing for multiple Children on the same node without having security issues.

Example usage

import base
import os

root_node = base.Node(parent_key=os.urandom(16), name=b'root_node', password=b'example pass')
root_key = root_node.get_key(password=b'example pass')

# needs the root_key to create new child
user_one = base.Node(parent_key=root_key, name=b'user_one', password=b'users pass')
user_key = user_one.get_key(password=b'user pass')
root_node.children.append(user_one)

netflix = base.Node(parent_key=user_key, name=b'neftlix', content=b'Netflix password')
user_one.children.append(user_one)

del root_key
del user_key

# later for auth

passw = input("Enter your password: ").encode("utf-8")
neftlix = user_one.get_child(["neftlix"])
user_key = user_one.get_key(password=passw)
netflix_key = user_one.get_child_key(key=key, path=["netflix"])
del user_key

print(netflix.get_content(netflix_key).decode("utf-8"))
del netflix_key
