Package pvss implements public verifiable secret sharing as introduced in "A Simple Publicly Verifiable Secret Sharing Scheme and its Application to Electronic Voting" by Berry Schoenmakers.

CoefficientsToPriPoly returns a PriPoly based on the given coefficients.

NewPriPoly creates a new secret sharing polynomial using the provided cryptographic group, the secret sharing threshold t, and the secret to be shared s.

NewPubPoly creates a new public commitment polynomial.

RecoverCommit reconstructs the secret commitment p(0) from a list of public shares using Lagrange interpolation.

RecoverPriPoly takes a list of shares and the parameters t and n to reconstruct the secret polynomial completely, i.e., all private coefficients.

RecoverPubPoly reconstructs the full public polynomial from a set of public shares using Lagrange interpolation.

RecoverSecret reconstructs the shared secret p(0) from a list of private shares using Lagrange interpolation.

PriPoly represents a secret sharing polynomial.

PriShare represents a private share.

PubPoly represents a public commitment polynomial to a secret sharing polynomial.

PubShare represents a public share.
