Shamir Secret Sharing is a secure tool implementing Shamir's Secret Sharing (SSS), a cryptographic method that allows you to split a secret into multiple shares. Unlike encryption, SSS ensures that your secret can only be reconstructed when a predetermined number of shares are combined together. For example, if you split a secret into 5 shares with a threshold of 3, any 3 shares can reconstruct the secret, while having only 2 shares reveals nothing about the original secret. This mathematical property makes SSS ideal for securing sensitive information like cryptocurrency keys, passwords, or any confidential data that requires distributed trust. To prevent backdoors in the implementation, the app transparently displays the complete polynomial coefficients used during the secret splitting process. Each participant can independently verify their share by checking that it corresponds to a point on the polynomial where P(x) equals their share value. The complete visibility of coefficients and the degree of the polynomial matching the threshold ensures that the authority cannot manipulate the sharing process, as any tampering would be immediately detectable by participants. Key Features: • Split secrets into customizable number of shares (up to 10) • Set custom threshold for reconstruction • Verify reconstruction immediately after splitting • Copy individual shares or all at once • View polynomial coefficients for verification • Combine shares to reconstruct secret
