Expand description

The blinding factor for a ValueCommitment.

Implementations§

Source§

impl ValueCommitTrapdoor

Source

pub fn random(rng: impl RngCore) -> Self

Generates a new value commitment trapdoor.

This is public for access by zcash_proofs.

Source

pub fn from_bytes(bytes: [u8; 32]) -> CtOption<Self>

Constructs ValueCommitTrapdoor from the byte representation of a scalar.

Returns a None CtOption if bytes is not a canonical representation of a Jubjub scalar.

This is a low-level API, requiring a detailed understanding of the use of value commitment trapdoors in the Zcash protocol to use correctly and securely. It is intended to be used in combination with ValueCommitment::derive.

Source

pub fn inner(&self) -> Scalar

Returns the inner Jubjub scalar representing this trapdoor.

This is public for access by zcash_proofs.
