Split Secret

The purpose of this software is to splitt a secret over multiple people. Just if a defined amount of this people meet together they can encrypt the secret and have access to it.

requirements

system

This software is developed for and on an Arch Linux system.

setup

Before executing the script it may be necessary to install the following software packages:

pacman -S gpg tar python pip python-pip
pip install numpy

commands

cleanup data

cleanup for user

To delete all data which isn't necessary for the user:

python scripts/main.py --mode cleanup --user "<<user>>"

delete all data

To delete all data execute:

python scripts/main.py --mode cleanup

delete decrypted data

To delete all decrypted data execute:

python scripts/main.py --mode cleanup --file-types decrypted

delete all encrypted data

To delete all encrypted data execute:

python scripts/main.py --mode cleanup --file-types encrypted

decrypt

decrypt automatic

To decrypt the data execute:

python scripts/main.py --mode decrypt

decrypt accumulated file

To decrypt the accumulated datafile execute:

python scripts/main.py --mode decrypt --meta

decrypt defined user

To decrypt the data for a defined user execute:

python scripts/main.py --mode decrypt --user "<<user_id>>"

addtional instructions

In the INSTRUCTIONS.md file the master encrypter can leave additional instructions.

encrypt

encrypt main data

python scripts/main.py --secret-holders-amount "<<amount>>" --quota "<<quota>>" --mode encrypt --master-password "<<master_password>>" --input-directory "<<input_directory>>"

generate encryption data

To encrypt the master-password file and to create the neccessary encrypted meta data execute:

python scripts/main.py --secret-holders-amount "<<amount>>" --quota "<<quota>>" --mode encrypt --add-user-information --master-password "<<master_password>>" --meta

generate encryption data with user info

To encrypt the master-password file and to create the neccessary encrypted meta data with additional user infos data execute:

python scripts/main.py --secret-holders-amount "3" --quota "50" --mode encrypt --add-user-information --master-password "<<master_password>>" --meta --add-user-information << EOL
