It consists of:
A general-purpose encoding/decoding tool for any text secret:
Split any text into n shares with a configurable threshold k
Combine k or more shares to reconstruct the original
Supports up to 255 shares (GF(256) field limit)
Hex-encoded shares with one-click copy
The SSS BIP-39 Seed Phrase Encoding Tool
a purpose-built tool for protecting BIP-39 cryptocurrency wallet seed phrases.
BIP-39 validation: checks word count (12/15/18/21/24) and format
offline: live network status banner warns if you’re online
masked input: seed phrase hidden by default with show/hide toggle
a step-by-step flow: enter → configure → generate
Download shares: export all shares as a .txt file
Viewport toggle: switch between mobile and desktop layouts to preview responsiveness -> Uses crypto.getRandomValues() for cryptographically secure randomness
How it works:
Shamir’s Secret Sharing splits a secret into n pieces such that any k pieces can reconstruct it, but k − 1 or fewer reveal absolutely nothing about the original.
The scheme works by:
Treating each byte of the secret as a constant term of a random polynomial of degree k − 1
Evaluating that polynomial at n distinct points over the finite field GF(256)
Each evaluation point becomes a share
Reconstruction uses Lagrange interpolation at x = 0 to recover the constant term All arithmetic is performed in GF(2⁸) using the irreducible polynomial x⁸ + x⁴ + x³ + x + 1 (0x11b), which ensures every non-zero element has a multiplicative inverse.
