Shamir Safe

Shamir Safe: Protect Your Crypto with Secret Sharing 🔐

Secure your cryptocurrency wallets using Shamir's Secret Sharing (SSS) — the same cryptographic standard used by banks and security professionals. Split your seed phrase, private keys, or any sensitive data into multiple encrypted shares. No single share reveals your secret.

🛡️ HOW IT WORKS: Shamir's Secret Sharing splits your secret into N shares, requiring only K shares to reconstruct it (K-of-N threshold).

Example:

• Split seed into 5 shares
• Require 3 shares to recover
• Distribute shares to trusted locations
• Lose 2 shares? Still recover your secret!
