Unkn8wn69 creates 'Polyseed Secret Sharing Tool' for Monero

Unkn8wn69¹ has created an experimental Monero Polyseed Secret Sharing Tool (psst)² for air-gapped environments like Tails³:

It’s a Python CLI application that uses Shamir’s Secret Sharing Scheme to back up a Monero polyseed. [..] Check it out, and let’s discuss how we can make the Monero experience more secure!⁴

Features & roadmap overview

[x] Convert monero polyseed seed to small hexstring
[x] Generate a set of secret shares (multiple groups, master threshold etc.)
[ ] Passphrase protection
[ ] Ability to generate secret shares from arbitrary data
[ ] Codebase enhancements for simplicity and clarity
[ ] Direct integration with Trezor's shamir-mnemonic for streamlined processes

To support the development of the project, consider donating some XMR to the address listed in the Github repository⁵.

Unkn8wn69 has also recently created a Telegram bot for Trocador AnonPay, as reported⁶.

Note that the project is still in ‘experimental stage’ and the source code has not been audited. Contributions from those with cryptography and coding expertise are welcome.
