Adi Shamir published How to Share a Secret in november 1979. Decades later, with the boom of cryptocurrencies, Shamir secret sharing resurface. How to deal with private keys belonging to a group instead of individual such as non-profit organizations and companies… In his scientific publication Shamir presents a threshold schemes ideally suited to applications in which a group of mutually suspicious individuals with conflicting interests must cooperate. Ideally, we would like the cooperation to be based on mutual consent. Satoshi Lab Improvement Proposal n°39 or SLIP39 is the document that formalize Shamir's Secret Sharing for Mnemonic Codes, a group of easy to remember words which are widespread to back up secret keys. This application is an attempt to implement SLIP39 in Flutter, an open source framework by Google for building natively compiled, multi-platform (Linux, Web, Android, Windows, MacOs, iOs) applications from a single codebase.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install subterfuge, simply use the following command:
sudo snap install subterfuge
Browse and find snaps from the convenience of your desktop using the snap store snap.
