Refkeys: A secure way for sharing secret (key).

Author & Developer: Ravin Kumar

This repository contains a tool for secret-sharing among two parties.

For example, lets say two parties A and B want to share a secret_key, such that only if they both agree than only they should be able to get the secret. Our software generates 3 individual keys, one for each party, and one for the mediator. When these keys are combined then only the secret_key can be revealed.

Advantage of our system:

• Even though the same secret is shared among G1={a,b,c} and G2={x,y,z}. The beauty of refkeys is that, even if some member of a group tries to contact other group members to generate the secret key, it can not be generated.
• Only when all parties of G1 agrees than only they can generate the secret_key.

Demonstration for generating individual keys:

import refkeys
key=refkeys.get_keys("secure_key_passed_here")
person1_key=key[0]
person2_key=key[1]
mediator_key=key[2]
## note: person1_key,person2_key,mediator_key are of type-list.

Demonstration for generating individual filekeys:

import refkeys
refkeys.get_keyfiles("secure_key_passed_here","person1_name","person2_name","mediator_name",path="./")
## note: names should be distinct, and mediator name is not mandatory.

Demonstration for generating secret key using individual keys:

import refkeys
....
secret_key=refkeys.combine_keys(person1_key,person2_key,mediator_key)
## note: person1_key,person2_key,mediator_key are of type-list.

Demonstration for generating secret key using filekeys:

import refkeys
....
secret_key=refkeys.combine_keyfiles(person1_key,person2_key,mediator_key)
## note: names should be distinct, and mediator name is not mandatory.

Installation using pip:

pip install refkeys
