Seed guardian: Split and reconstruct your groestlcoin BIP39 Seed using Shamir's Secret Sharing Scheme.

This software shares your BIP39 12 words seed in 15 words shares. For example, if you share your seed in 3 shares with a threshold of 2, you need 2 shares to reconstruct your seed, so you could lose one share, and somebody finding one share can't reconstruct your seed.

• Hexadecimal shares are humanized using BIP39 algorithm, so each share is encoded as a sequence of 15 words.
• Adjustable number of shares and threshold.
