Struct challenge_bypass_ristretto::voprf::UnblindedToken

#[repr(C)]
pub struct UnblindedToken {
    pub t: TokenPreimage,
    W: CompressedRistretto,
}

An UnblindedToken is the result of unblinding a SignedToken.

While both the client and server both “know” this value, it should nevertheless not be sent between the two.

Fields

t: TokenPreimage

t is the TokenPreimage

W: CompressedRistretto

W is the unblinded signed CompressedRistretto point

\(W = Q^{1/r} = P^{k(1/r)} = T^{rk(1/r)} = T^k\)

Implementations

impl UnblindedToken

pub fn derive_verification_key<D>(&self) -> VerificationKey where
    D: Digest<OutputSize = U64> + Default, 

Derive the VerificationKey for this particular UnblindedToken

pub fn to_bytes(&self) -> [u8; 96]

Convert this UnblindedToken to a byte array.

fn bytes_length_error() -> TokenError

pub fn from_bytes(bytes: &[u8]) -> Result<UnblindedToken, TokenError>

Construct a UnblindedToken from a slice of bytes.

Trait Implementations

impl Debug for UnblindedToken

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
