Expand description

Semi generic implementations to create new Hints

Required Associated Types§

Source

type HintSize: ArraySize

Byte length of a serialized Hint: public key + ciphertext + tag.

Required Methods§

Source

fn new( blinded_public_key: &BlindedPublicKey<K>, message: &Array<u8, L>, context: &[u8], csprng: &mut impl CryptoRng, ) -> Result<Self, Error>

Create a new Hint.

Source

fn from_blinding_factor_secret( blinding_factor_secret: &K::SecretKey, blinded_public_key: &BlindedPublicKey<K>, message: &Array<u8, L>, context: &[u8], ) -> Result<Self, Error>

Create a new Hint using a blinding factor secret.

Source

fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Deserialize from byte slice

§Security

Implementers must validate the deserialized blinded blinding factor and reject small-order and identity points with Error::InvalidPoint.

Source

fn to_bytes(self) -> Array<u8, Self::HintSize>

Serialize to byte array

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
