Implementations

impl BatchDLEQProof

fn calculate_composites<D>( blinded_tokens: &[BlindedToken], signed_tokens: &[SignedToken], public_key: &PublicKey, ) -> Result<(RistrettoPoint, RistrettoPoint), TokenError>

where D: Digest<OutputSize = U64> + Default,

pub fn new<D, T>( rng: &mut T, blinded_tokens: &[BlindedToken], signed_tokens: &[SignedToken], signing_key: &SigningKey, ) -> Result<Self, TokenError>

where D: Digest<OutputSize = U64> + Default, T: Rng + CryptoRng,

Construct a new BatchDLEQProof

pub fn verify<D>( &self, blinded_tokens: &[BlindedToken], signed_tokens: &[SignedToken], public_key: &PublicKey, ) -> Result<(), TokenError>

where D: Digest<OutputSize = U64> + Default,

Verify a BatchDLEQProof

pub fn verify_and_unblind<'a, D, I>( &self, tokens: I, blinded_tokens: &[BlindedToken], signed_tokens: &[SignedToken], public_key: &PublicKey, ) -> Result<Vec<UnblindedToken>, TokenError>

where D: Digest<OutputSize = U64> + Default, I: IntoIterator<Item = &'a Token>,

Verify the BatchDLEQProof then unblind the SignedTokens using each corresponding Token
