Shamir's Secret Sharing — split secrets into shares, reconstruct with a threshold

What is Shamir's Secret Sharing?

Shamir's Secret Sharing (SSS) splits a secret into N shares, where any K of those shares (the threshold) can reconstruct the original secret. Fewer than K shares reveal nothing about the secret. This implementation runs entirely in your browser — no data is ever sent to a server.

🔑 Split Secret

Divide your secret into N shares. K shares will be needed to recover it.

Total number of shares to create (2–255)
Shares needed to reconstruct the secret (2–N)
ⓘ Need 3 of 5 shares to reconstruct. Threshold K=3 provides >256-bit entropy.

🔒 Reconstruct Secret

Enter K or more shares to recover the original secret.

How many share strings you have (must be ≥ threshold)

ⓘ Enter 3 or more shares to meet threshold K=3.
