Module challenge_bypass_ristretto::voprf

An implementation of a verifiable oblivious pseudorandom function

Structs

• BatchDLEQProof
  A BatchDLEQProof is a proof of the equivalence of the discrete logarithm between a common pair of points and one or more other pairs of points.
• BlindedToken
  A BlindedToken is sent to the server for signing.
• DLEQProof
  A DLEQProof is a proof of the equivalence of the discrete logarithm between two pairs of points.
• PublicKey
  A PublicKey is a committment by the server to a particular SigningKey.
• SignedToken
  A SignedToken is the result of signing a BlindedToken.
• SigningKey
  A SigningKey is used to sign a BlindedToken and verify an UnblindedToken.
• Token
  A Token consists of a randomly chosen preimage and blinding factor.
• TokenPreimage
  A TokenPreimage is a slice of bytes which can be hashed to a RistrettoPoint.
• UnblindedToken
  An UnblindedToken is the result of unblinding a SignedToken.
• VerificationKey
  The shared VerificationKey for proving / verifying the validity of an UnblindedToken.
• VerificationSignature
  A VerificationSignature which can be verified given the VerificationKey and message
